Percy is the strongest Because he has many powers: hydrokinesis, limited cryokinesis, limited areokinesis( hurricanes and storms ),heat resistance, also able to control poisons and maybe even other liquids, his unpredictable sword fighting is better than Piper, Hazel,Annabeth, and Leo( who doesn't even use a sword or a dagger which Annabeth and Piper uses) and Frank Cause Frank uses the Bow and arrow, and doesn't really uses a sword but in The house of hades he did for a while but not for a long time. Percy's sword fighting is probably better than Jason's sword fighting cause Percy has been defeated monster in very small groups like 3 to 5 people, But Jason has been defeated monsters in big groups. Also people keep saying that Percy needs a water source to be stronger than other people like Frank, but it's not exactly true, as of The House of Hades, Percy can probably control blood in people's bodies cause Blood is partially water so if Frank turns in an animal he can concentrate on him and can kill him by controlling blood in his body (if he can control blood which is very possible as is partially water), that's how he can control poison cause it's partially water and also he can bring the " ocean" to him but will make him extremely weak and very tired as he did it in the Battle of the Labyrinth, as he made the volcano explode.Also percy can have power boots if he is in water and the water can heal almost any wound or poison, he can also solify water  so he can make a strong shield or walk on water if he concentrates and he is also very strong for example is held the sky in the Titan's Curse, and many other thing he did in the past...Also people say that it depends where Percy is for example if he is near the ocean or there's water he wins if he is on land it depends like if he is close to the river or stream or controlling liquids for example blood Maybe even  Juice ( as it is Half water with juice concentrate and sugar ) or any other type of liquids like may frozen water or icy water(if it's melting ) so on land It's limited. In the air He is totally useless unless if Jason and Percy are making storms together ( as u know that storms have water) but if they are not together he is totally useless since Percy can't control storms in the air without water. He can win with sword fighting, also it's said that Percy can make earthquakes as Poseidon is the earth shaker we don't know.Jason is almost as strong as percy but He gets to tired and percy can heal and get power boots from water and Jason can't But the only disadvantage it that Jason can fly but percy Cant So  I say that Percy is the strongest following Jason, than Frank, than Leo than Hazel Than Piper than Annabeth.
