Best Trios in the Percy Jackson and the Olympians and Heroes of Olympus Series

I love them, they work so well together (though Percy and Annabeth did fight sometimes). I love percabeth and this is the ORIGINAL TRIO!
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 there the original trio, but I will always stand by the original PJO team: Percy, Annabeth, Grover, Thalia, Tyson, Nico, Rachel. Heck yeah

Percy can control water, Nico can control the dead, Thalia can control lighting and there all a child of the big three gods. The perfect mach!
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.
This is so much better than the sons of the big three. Thalia is so much better than Jason.
Oh lord, I don't ever think they can get along together... but I think they will be dam powerful together

Best trio I loved their team work and I remember the last time they worked together alone when they went to collect the vial thing to save one of them that was very emotional for me cause that was their last adventure with just the three of them, the parts in book I remember the most are their adventures and the lost hero was good book not best but good tho.
This is just beautiful!
Heroes of Olympus trio!
Lost Hero trio yas

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 to tell about his dying!
Reason why this is the best trio. Leo has fire powers to fight and mechanic powers that he can 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.
Best trio in HoO. Even though the seven are awesome, I love the original team better: Percy, Annabeth, Grover, Thalia, Nico, and Rachel forever
Yes! Hazel and Frank were the only ones Leo trusted to tell that he was going to die!
They make me laugh all the time.
They are just great. Great.
I just love these guys
I just like this

the best trio, in my opinion. Nico is my favorite Rick Riordan character, out of all the series, and 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 likeable since none 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
They are like the second original trio: The daughter of the goddess of war, a son of the big three and a satyr.

This trio is very imortianal and cute... I am so sad it had to end... After Thalia became a pine tree one of them was gone and then years later Luke separated from Annabeth and then in the end of sea of monsters Thalia returned but since Luke wasn't there the trio wasn't fixed... I can't say more it's so sad...
I'm bawling. The relationship between of three of them was so pure and amazing and ugh. Dam Trio and Broken Trio forever.
The apparent "broken trio." Saw a fan art this morning and was left bawling for eighteen hours straight. Don't ask.
They always make me kind of sad... But they are obviously really great trio!

They never seem to get along, but when the three are working together, there are just so strong!
Finally two girls and one boy, I mean, in most books with trios its two boys one girl!
So funny and great
They are all so nice! Hazel and Frank accepted Percy in an instant, even before they knew him! They work great together, and are all so powerful.
Even though they didn't know him that well, they stood up for him and stuck with him no matter what. Frazel are the epitome of kindness, acceptance and sweetness.
I love this trio. It's got Percy who is awesome, Hazel who is really cool and interesting, and Frank who's just really wholesome and great
An interesting dynamic by making a Greek, unorthodox hero team up with Roman, by the book heroes.
Best girl trio and girls rule so I mean obviously this is best trio, the girl trio was better than any boy trio because the girls are more heroic, powerful, better, awesomer, brave, etc.
Girls rule. They are the queens. Need me to say more?
Girl power! Boss girls!
I agree all the way!
Love rival trio
I hat this group. Percy and annabeth left bob to die. That just broke the group.
I loved the Tartarus parts because of these kids teamwork they worked so well together.
I laughed at the Dam jokes for days omg.
I want this dam trio to win!
I like the Bobs
Love the bob's
Guys if they one 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
Kill Dad. I like it.
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!
Three of my favorites
I loved their part to be honest when the three of them went into the underground pool thing was great teamwork I liked that part.
They were good trio those girl inseparable.
Book two trio
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 knew Percy's weakness.
