Top 10 Best Heroes of Olympus Characters

The Top Ten
1 Leo Valdez Leo Valdez is a major character from the book series Heroes of Olympus by Rick Riordan. He is one of the seven heroes in the Prophecy of Seven. He is a Greek demigod and is the son of Hephaestus / Vulcan, and has the ability to create and manipulate fire (pyrokinesis).

Dude is just so pretty! Why my favorite, its not a question. He is the definition of jokes. Poor guy has had a worse past than Nico himself, and still wears a smile on his face, still has the heart to make jokes. He has gone through so much, has so much courage, but in the book he is portrayed weak. I just love this man. Tbh, sometimes I wish I could be Calypso.

He is by far the funniest character in HOO. He is sarcastic and has some major laugh out loud moments, but also so insanely touching and emotional moments. The fact that he had such a hard life and still wears a smile on his face is amazing. This is one character that should never go overlooked.

So it was just sad. Leo's past was sad, and his whole "seventh-wheel" and "no girlfriends until the end but then in the end he died" thing was just sad. I ship him with Hazel since they were incredibly connected, and... how can I explain it? It was just complicated... nobody's past was as sad as his (even Nico's), and he wears a mask of laughter to hide his pain. He was hilarious, but that was just one side of him he created to hide his true feelings, and that was what made me love Leo. Just think of it. He was the only character that (Hazel doesn't count, she's a daughter of Hades... and she ends up in Elysium) ACTUALLY died and caused ACTUAL grief among a lot of people. You know, only Sammy mourned about Hazel death? I'm sure I'm gonna lose my appetite for weeks about Leo's death... a loss of an excellent character! But thankfully he revived

2 Percy Jackson Perseus "Percy" Jackson is a fictional character, the title character and narrator of Rick Riordan's Percy Jackson & the Olympians series.

Percy Jackson is amazing. Second favorite character in all the books. He is loyal until the end, and if your a friend he will love you like no other. He deserves the love he finds in Annabeth. He is also smart, but in the most underrated way ever. The whole Diet Coke scheme was ingenious. He is amazing and is my favorite title character in any book series I have ever read.

Percy is actually a pretty incredible main character, which is unfortunately kind of rare. He provides a lot of humor without being overly obnoxious, he's incredibly dedicated to his friends, and he proves just how much he really loves Annabeth by falling into Tartarus with her. My top ten favorites are (1) Percy Jackson, (2) Annabeth Chase, (3) Hazel Levesque, (4) Frank Zhang, (5) Mrs. O'Leary, (6) Buford, (7) Blackjack, (8) Ella, (9) Rachel Dare, and (10) Chiron.

Honestly, I have favorite parts in every single book of HOO about mainly him. In the Son of Neptune, I love the way he talks about Arion. And that the only thing that kept him going was just Annabeths face. In the Mark of Athena, I love his little diet coke escape plan, it had me dying. And he sneaks out with Annabeth. Love that part. In the House of Hades Percy is just so caring about Annabeth I nearly cried. And in Blood of Olympus he is just the normal Percy I love. Shame on those who don't vote him, even if he's 1st!

3 Annabeth Chase Annabeth Chase is a daughter of Athena and one of the main characters of both the Percy Jackson & the Olympians series and the Heroes of Olympus series. She's also Percy Jackson's girlfriend and has no particular powers aside from her brains and tactics.

What I really like about Annabeth in this series is that she's almost out of her element. Like, her companions can harness the power of the sea, fly, manipulate the earth, summon fire, mind-control, and shapeshift...whereas she has to rely entirely on her wits. This idea really shines through in The Mark of Athena, when she is forced to leave the protection of all other six heroes of Olympus and seek the lair of Arachne all by herself. That was incredible, and the cliffhanger was jaw-dropping. Usually I hate it when some really powerful villain gets stupidly tricked and is like, "Aww, man!" at the end. But this felt a lot more plausible and it shows how brilliant Annabeth can be, even in the worst situations.

Annabeth is such a strong character. All the rest of the seven have supernatural abilities (e.g. flying, charmspeak, shapeshifting) whereas she only has her brains. Yet I feel she is the strongest out of all of them because she uses common sense and logic to win battles, and she outsmarts the enemy rather than beating them in a battle of physical strength. For this she can be underestimated, but she always manages to come out on top. Annabeth is a highly determined and ambitious character, and she will stop at nothing to reach a goal and get what she wants. She has had a hard time trusting people at times (which is probably due to her past relationships with her family and with Luke) and often prefers to work independently. I think for this she is misunderstood by people such as Leo, who find her intimidating and stand-offish. But Annabeth feels she has to do everything herself, for fear if she allows someone else to carry out a task that they will get hurt or won't carry it out as well as she would (to be honest she probably would do the job best). Annabeth is such an under-appreciated character in so many ways. She is often viewed merely as Percy Jackson's girlfriend and labelled "the smart one" of the seven. But there is so much more depth to her character and she is by far my favourite in the series.

4 Nico di Angelo Nico di Angelo is a fictional character created by Rick Riordan. He appears in Percy Jackson & The Olympians, Hero of Olympus, and parts of Trials of Apollo. As a son of Hades, the boy is a demigod. He befriended Percy and had many roles in his long time appearance including stopping Minos, fighting Titans, traveling back and forth camps and during the war with Gaea he had to transport the Athena... read more

I simply love Nico. He is so full of emotions, pain, sorrow, and, despite this, he is an important presence for the Seven with his powers and his love too throughout the whole series. He can fight everything and he always exits from every single battle - with monster or with feelings - a little bit weakened, a little bit more broken, but still there, with his grin, his tears and a lot of problems he never asked for but anyway has to deal with. Besides, even if I didn't know him, I would love him only for saying that "those who are heartless, once cared too much". A sentence which means a lot to me. If I were a character in any book, I would probably have the way of thinking of Annabeth - curious, smart, a bit brave too - but totally the heart of Nico.

Honestly, Nico is hands down my favourite character from the books. He has so much character development, we see him slowly change from the curious, enthusiastic little kid to the survivor of Tartarus. He's strong, capable, cunning and skilled but he's also relatively understanding, relatable and I love the fact that he is gay. Some people insist that it was sudden but I had realised by the end of the Last Olympian I simply could not see Nico with a girl, though I did think he was just going to stay single. He's a well thought out character who is flawed, can be horrible and is quiet, but he's great representation for introverted people, LGBTQ+ people, Italians, goth/emo people and more. Also, the fact that he's so loyal to Percy and Hazel really warms my heart and it seems to me he's just as loyal as Percy is.

5 Hazel Levesque

Hazel has a really cool background. I like the guilt that plays into her story, and how she feels responsible for everything that's happening. When she sees Leo and is like, "Aaaah! Sammy!" that was amazing. I also loved when she took Frank with her into her flashback and he entrusted his wood to her.

I never understood why people don't like her. She's amazing! She came back from the dead after SEVENTY YEARS. She was bullied and was rescued by Leo's great- grandfather, she had to move away from the one person who actually loved her, after she comes back she runs into a descendant of her old boyfriend but is still an awesome fighter!

She's a badass. She would help Leo teach me about making stuff, and help Percy teach me to fight. then we'd just crash and watch horror movies.

6 Reyna Avila Ramírez-Arellano

Reyna is such a strong independent character who is vital for the heroes of Olympus series. She is such a queen I mean not only does she have such a sad past but she grew from it. She became praetor of the twelfth legion fulminata and keeps on doing the impossible. I mean going to the ancient lands alone and surviving is amazing but traveling the Athena Parthenos to camp half blood just because it was the best chance at peace is pretty freaking heroic. Not to mention all the struggles with the wolves and her past and Orion. She had enough guts to share her past and gain a the trust of her crew ( nico and coach hedge) and taking down Orion when both the amazons and hunters of Artemis combined wasn't enough

Reyna is honestly one of my favorite characters in the series. Look at her life. Her backstory is one of my favorite ones. She had to kill her father to protect her sister. She then is imprisoned by pirates. She goes to Camp Jupiter. She has such a tough personality. She became praetor along with Jason. She loved Jason. But when she realized Piper and Jason were dating, she didn't let her grief ruin her. And, I think that she and Jason would've actually had a better relationship than Piper and Jason. She is a strong, confident person on the outside, but when you know her better, you realized how damaged she is. Like I said, she killed her father. Because she loved her sister. Then Jason goes missing, leaving her basically in charge of the camp alone. Then he comes back- BUT WAIT! He has a girlfriend. And she really loved him. But she never showed it. Think about if your life-long crush, went missing for almost a year. You are paranoid, but trying to stay calm. But then he shows up with a new girl and doesn't understand how much you cared about him. How would you feel? I would want to break down and cry my heart out, but she couldn't. Because she had to stay strong for the camp. She really deserves to be higher. She is role model to me, and she should be one to you too.

7 Calypso

I love that Rick freed her from her curse and brought leo back to her.

Kind and caring but also tough and don't-you-dare-mess-with-me.

Calypso is pretty cool! She is strong and lovable.

8 Frank Zhang

Frank is really cool, but I feel like a lot of people don't appreciate him like they should. I love the whole baby-face cuddly vibe that he gives off even though he's the son of Mars and just wants to be taken seriously. I'm sorry, but honestly Leo Valdez annoys me SO MUCH, and he's such a pain to poor Frank, tormenting him at every chance he gets. And it drove me insane when he was starting to get interested in was like, "Back off dude! Frank and Hazel were a thing WAY before you came into the picture." But it turned out all right. Oh, and one of my favorite lines EVER is "So your name's not Sammy?" I was dying laughing XD

Frank is underrated. He deserves more credit. Yes, he didn't suffer as much as other demigods such as Annabeth, Nico, or Leo, but he did so much AND his power to shapeshift is very overlooked. That power could be used for so much and he demenstrates it constantly.
Also, the fat that he did all of this while trying not to light a stick on fire is impressive! especially since he was almost always around Leo.

9 Piper McLean Piper McLean is a fictional character created by Rick Riordan in The Heroes of Olympus series. She is one of the Seven of the prophecy and is the daughter of Aphrodite.

To be honest she really does a lot, she is just not portrayed as a badass, so people don't take her as seriously as she deserves. She stopped so many battles within the groups and outside. It's important to know that she takes care of the gangs emotional state, as well as helping them kill the enemies. She is a daughter of beauty, but is also super smart. This is unique and unpredictable. Anna Beth is smart because she is the daughter of Athena. Piper goes against those odds of being a typical daughter of Aphrodite and is clever and down to earth. She is also the only reason Leo stayed at wilderness and didn't run away, its because he found a sister.he found family after a long time of being alone. She also risked her own life to save nico, who she didn't even know at that point.

Piper so deserves more love. The seven wouldn't have been able to sussed without her. She's done so much and doesn't deserve the hate she gets. People say she just sits there and looks pretty and I'm like, dude, did you read the book. that is her entire internal thought the entire series. one of her main goals is to prove she's is more than her parentage. At the beginning of the story, Jason says that she was pretty and she was obviously trying to cover it up. She hates the fact that her father is famous because it makes people not take her seriously. She also hates her mother a bit for branding her and a 'child of aphrodite' because she wants to be more than that. and she succeeds. At least for me, she did. I admit at first I didn't like her that much. I felt like she was a bit boring and flat. But then I reread with the intention of not focusing on Percy, Annabeth, or Leo but focusing on the whole of the story and I realized that Piper is so much more than everyone sees her as. She may not have been the hero of 2 great wars like Percy, or always has a plan like annabeth, or can build anything like Leo, she hasn't come back from the dead like Hazel nor has she had a traumatic life like Nico, but Piper went against all the barriers of her parentage and for that, she will always be one of my favorite characters and have loads of respect

10 Jason Grace Jason Grace was the Roman demigod son of Jupiter (Roman God of the Sky) and the late actress Beryl Grace, the younger brother of Thalia Grace (whom Beryl had with Jupiter's Greek form Zeus), the former co-praetor of Camp Jupiter, the Counsellor of Cabin 1 at Camp Half-Blood, the former boyfriend of Piper McLean and one of the protagonists of the 2010-2014 Greco-Roman mythology book series The Heroes... read more

I don't think people understand that although he's "perfect" with so many characters, there had to be one of them. He's very powerful and I don't think he should be compared to Percy because that's not fair to either of them. I think people often forgot Percy was the original character, so duh he's going to be a bit more OP (overpowered) than is realistic and he also gets more focus in terms of character development since the first series is literally named after him. Jason's very Roman in that he's disciplined and respectful. Although he needed more character development I feel, he was still a good person and very skilled. I think Jason often is unfairly judged, and although I don't think he's the best character he isn't as bad as people say he is. Rest in peace Jason, you were brave and you deserve Elysium.

If I'm being honest he wasn't really my favorite at first, but now I like him a lot because of how I can relate to him. I love his idea of expanding/choosing his family and would love to do the same. I also understand why he's so "perfect". I understand what it's like to try your best not to make mistakes that others have made so that you don't end up like them. He is definitely the character that I connect with the most. People say he is a worse version of percy but I think they are looking at the wrong qualities(not saying that jason is better though. Percy>Jason). Jason has definitely not done as much as percy, but he is still brave. His sacrifice helped Apollo and Meg complete that part of there quest and without it, they would probably all be dead. He tries his best to please everyone and keep peace and I admire him for that. R.I.P. Jason.

The Contenders
11 Gleeson Hedge

Coach Hedge is hilarious. He isn't that smart, because no matter the situation the only solution is to yell 'DIE' holding a club. It adds some hilarity to some moments that have the potential to be funny but normally wouldn't. I love Coach Hedge!

Hedge should be higher up. HE's not the best but he's SO funny but also protective and understanding.

He technically counts as a main character, since he is there almost as often.

12 Festus

What can you not like about Festus. He is a BRONZE DRAGON. There is nothing not to love. Also, the whole suitcase thing…amazing. I love Festus and the human that created him.

OH MY GOD! I love metal fire breathing dragons repaired by my favorite human in hoo. Festus is just amazing.

I want a metal dragon that actually breathes fire and flies and can compact into a suitcase!

13 Mrs. O'Leary

She is friendly and awesome. I know I want her as my pet.

Giant dog biscuits

How dare you! Ms.O'Leary is absolutely cool! Really,a friendly hellhound? That's just so COOL!

14 Thalia Grace

She is so powerful and cool. She could totally take down anyone in her path and is so loyal. She literally got turned into a tree because she chose to protect her friends.

#1 favorite character. She awesome and you can't deny it. She is super badass and one of the best fighters not to mention that she's lieutenant of the hunters of Artemis. Thalia's also so noble, she died to save her friends. How much better can you get? Rick needs to give her way more attention. She deserves her own book if you ask me.

Thalia is fierce,fun and great in battle. She is the daughter of Zeus and the sister of Jason. She joined the hunters of Artemis and is my favorite character ever! You go girl!

15 Blackjack

Blackjack is always there for Percy when he needs him. He even warmed up to Nico, who smelled like death, eventually.

Blackjack may annoy Percy but he's never let him down and will push himself to his limits and beyond to help him.

Oh Yeah! Anyone who thinks that Blackjack is not Awesome is Dead!

16 Luke

At the beginning of the pjo series, he was one of, if not my favorite character. And then he had to go and break my 10 year old heart. Even though he made some tremendous and unforgivable mistakes, he is one of the best characters. He was a good person who was neglected. He didn't deserve what hand he got dealt, and I pity him. After he died, I was like 'good riddance' but know thinking back on it, he was one of the best characters. I ship him with Thalia all the way.

I mean... He sucked. Then you found out about him and how can you not absolutely love him. He realised how wrong he was and thought he'd save the world and die as an apology.

I really don't understand why everyone hates him. He has good reasons cus its not like the Olympians are good parents. I personally like Luke as a character. Not my favourite but I still like him as a villain

17 Tyson

Tyson is just really sweet in my opinion. He's just so lovable.

Tyson is by far the most lovable character in pjo. He is so sweet and innocent and would do anything for his friends. I love him

Do I really need to say anything?

18 Bob

Bob I said an emotional character who does anything for friends and even when he realizes what had happened he still stays with them and saves Percy and Annabeth's life.

Bob is cool and awesome! It was sad that he sacrificed himself.

Oh Bob. That amazing titan. He deserved more. I love him.

19 Zoe Nightshade

She is sort of mean at first but so loyal. She died for Artemis and trained her Hunters well. Also the dam scene in one of the books is hilarious!

She wasn't in heros of Olympus only in Percy Jackson and the olympians

I don't think she should've died but at least it was to defeat Atlas

20 Small Bob

Small Bob is awesome. I love Bob too of course but Small Bob that little bit more

Best cat ever! Small Bob and Festus are the best.

Small Bob is better than everyone.

21 Will Solace

My friends and I were shipping each other with PJ HoO characters and I got shipped with Will. I love Will, and I don't like the people in the fandom that make him gay and like Nico.

The best boyfriend Nico could ever wish for! He is literally amazing!

He makes Nico happy, he's a ball of sunshine. What's not to like?

22 Chiron

Yeah but Chiron is super cool!?!? I mean like,seriously,if it wasn't for him Annabeth wouldn't have really been able to learn how to really wield her awesome fighting skills she already had!

He is a strong brave and always knows the right words to say.

Chiron is strong and brave and knows what words to choose.

23 Grover Underwood

Grover is probably the most loyal character in all of Pjo. I know some people may be thinking, 'what? No way' but hear me out. Grover risked his life for Percy. Multiple times. He was also the moral compass of the trio. Percy was the hero flat out, Annabeth was the know it all(I love Annabeth by the way), but Grover was the hard one to pin point. Grover was the moral compass, the lovable nerdy dorky character and the understated hero all at once. I also give him major props because he had to look at that pine tree(Thalia) every single friggin day, knowing he was a major reason of why she was there in the first place. I feel like I connect the most to Grover and am most like Grover than any other character. He blames himself for virtually everything and always feels like he has to apologize. I love Grover and I am happy he got what he wanted in the end.

The whole first series, and Percy's survival would not have been possible with our Grover Underwood! The protector of nature and Percy should never be forgotten!

24 Rachel Elizabeth Dare

She is so under-appreciated! Rachel gave up dating to become the oracle, guided Percy and Annabeth through the labrinyth without even fully knowing what's going on, saved Percy from the empousa

She is feisty and can give out prophecies. She also had a crush on Percy - aside from and Annabeth and yet Rachel and Annabeth get along fine in The Lost Hero. Not only that but they both search for Percy together.

I don't understand this. Rachel is amazing. We hate her for having a crush on Percy, which is stupid. We all had a crush on Percy. Rachel just happened to be the closest to actually getting with him and potentially ruining Percabeth, so we hate her. We need to just freaking let it go. She became the freaking Oracle, which was super dangerous. Stop hating on her. She is totally amazing.
