They start off third-rate and low-power. Then after a particularly bad fail against a Gigantamax Grimmsnarl, Tony, leader of Team Power, decided to come help them not get fired and disbanded, even letting them co-use the base.
Pikachu is the leader. He’s got the stalwart personality Pikachu have become known for.
Charmander is nervous, and often has misgivings about going into battle
Squirtle is very strange. He’s a master of interrogation regardless, though.
Bulbasaur is easily the most normal one. He keeps everyone grounded. He’s also Squirtle’s boyfriend. He doesn’t usually go on rescue missions.
They’re based on Ash’s team from the Pokémon cartoon.
