Top 10 Best Trios in the Percy Jackson and the Olympians and Heroes of Olympus Series
Rick Riordan didn't just give us monsters and prophecies. He gave us squads. Tight-knit, chaotic, ride-or-die groups that had each other's backs through labyrinths, lightning storms, and literal trips to the Underworld. And when you look back on the biggest battles and best moments, it's often these trios that made them unforgettable.Every trio has its own flavor. Some are balanced like a perfect team build in a game with brains, brawn, and comic relief all in sync. Others are total disasters in motion yet somehow still get the job done. You've got friendships that grew out of loyalty, partnerships forced by circumstance, and sometimes just a bunch of kids tossed together by the gods who decided it was their problem to solve. And they usually did. Sort of.
You get to decide which trio deserves top honors. Maybe you're all about that original Camp Half-Blood energy. Maybe you love the more complicated and darker dynamics that show up later in the story. No judgment here. Just vote for the ones you think were the most entertaining, most heroic, or maybe just the most fun to root for.

They are the original trio. The first trio. Percy, Annabeth, and Grover are the originals, so you can't beat them!
The first trio. The original trio. Percy, Annabeth, and Grover are the originals, so you can't beat them!
Sure, they're the original trio, but I will always stand by the original PJO team: Percy, Annabeth, Grover, Thalia, Tyson, Nico, and Rachel. Heck yeah.

JESUS! I probably shouldn't be saying that because Jesus is Christian, but DANG! This trio would be unstoppable. Also, I absolutely love these characters, especially Percy and Nico. This picture is also really cool. I don't know what Thalia is doing.
Percy can control water, Nico can control the dead, Thalia can control lighting, and they're all children of the Big Three gods. The perfect match!
This is so much better than the sons of the big three. Thalia is so much better than Jason.

I know that a ton of people will probably hate me for saying this, but I kind of wish this trio had stayed together and Annabeth hadn't joined Grover and Percy.
And yes, if they hadn't been a trio at first, Percabeth never would have happened, and it's impossible to imagine Percy without Annabeth as his girlfriend. But it also feels kind of incomplete because this trio was just thrown away and replaced with Grover, Percy, and Annabeth.
If only both trios could have existed, but then I think Luke and Percy might have gotten into fights over Annabeth. Overall, this is the OG trio, and I love it.

The best trio, in my opinion. Nico is my favorite Rick Riordan character out of all the series. His and Reyna's relationship was so well developed that if Nico liked girls and Will was off the table, I feel like they could have been a perfect couple. (Coming from the biggest Solangelo shipper of ALL TIME, this is meaningful.)
I found these characters more likable since, in my opinion, nobody was insufferable, and all of them were fairly strong.
Their quest was a huge success, and I love Reyna and Nico working together as a powerful team. Plus, furry goat war machine Coach Hedge? What's not to like?

Best trio! I loved their teamwork, and I remember the last time they worked together alone when they went to collect the vial to save one of them. That was very emotional for me because it was their last adventure with just the three of them.
The parts in the book I remember the most are their adventures. The Lost Hero was a good book. Not the best, but good.
First trio in Heroes of Olympus and the first people in The Lost Hero. So, yeah, nice trio. And there is a love story in there, so heck yeah, got my vote.

Reasons why this is the best trio: Leo has fire powers to fight and mechanic skills that allow him to make almost anything. Hazel can detect traps and give cursed gems. Frank... do I have to say more? Well, Frank has animal-changing powers. Happy?
Sure, they fight, but this is the best trio ever! Hazel and Frank are so nice. Even though they only knew Leo for the quest, he trusted them enough to tell them about his dying!
Best trio in HoO. Even though the seven are awesome, I love the original team better: Percy, Annabeth, Grover, Thalia, Nico, and Rachel forever.
I LOVE their dynamic. It's sometimes rocky, but put together, they are all such powerful heroes.
So funny. I laugh at them all the time. They just have those good vibes.
They make me laugh all the time.
Alright, these people are the best. They worked awesomely together, sacrificed themselves, and never gave up. Also, HILARIOUS. It redefines the word. I couldn't sleep at night because I couldn't stop laughing. Ultimate sarcasm.
OKAY, so this should be in the top 5 at least, for sure. Personally, top 3 definitely. The Son of Neptune trio had more bonding and friendship than the Hazel-Leo love triangle, for sure.
It sucks that it wasn't majorly addressed later, but you can still see Frank and Percy's friendship later on. (Also, there are so many great undiscovered friendships in those books.)

They never seem to get along, but when the three are working together, they are just so strong!
Finally, two girls and one boy. I mean, in most books with trios, it's two boys and one girl!
Best girl trio! Girls rule, so I mean obviously this is the best trio. The girl trio was better than any boy trio because the girls are more heroic, powerful, better, awesome, brave, etc.
I haven't read the book with Hazel yet, but I support any team where Annabeth and Piper pair up. They make such a good team.
Girls rule. They are the queens. Need me to say more?
The Newcomers
They were a good trio. Those girls are inseparable.
Well, uh... they all made bad choices but sacrificed themselves in the end. Luke: Duh, he almost destroyed the world. Silena: passed information to Luke (spy). Ethan: joined up with Kronos and knew Percy's weakness.
I was left crying for days after The Last Olympian because of how sad their deaths were.
They are a good team. Although it is a little awkward since Percy has a crush on both girls.
I loved the Tartarus parts because of these kids' teamwork. They worked so well together.
Guys, if they wanted to kill every monster, demigod, and mortal, they could. Without breaking a sweat.
Love the name. So true. But most of the time, they would be flirting with mortal women.
The Dam Trio is the best. It is constantly brought back.
I laughed at the Dam jokes for days.
The sons of the Big Three! They all work well together. Percy can control liquid, Nico can summon dead spirits to help them fight, and Jason can fly and control the weather to give them the advantage.
I just felt like Jason without Piper isn't actually bad, and the three grouped together is, well, you know what I mean.
The best three demigods ever in a trio!
I loved their part, to be honest. When the three of them went into the underground pool thing, it was great teamwork. I liked that part.
Yes, I love that trio! All are great people and huntresses of Artemis. BTW, my favorite goddess.
No. I hate this one. Just no. Apollo, Meg, and a villain? I hate it. And no, I'm not sorry.
I mean, why isn't this in the top? Nico is so sarcastic and blunt. Percy is just so sassy and sarcastic.
Leo is awesome. He is super funny. I am so on Team Leo!!
