Pokemon Trainer

No, he's not Ash.

Pokemon Trainer (called PT by his friends) is a Pokemon trainer from Kanto. You can tell because he robbed Oak rather than one of the other professors. It's unknown how many badges he has and if he has any other pokemon. His real name is yet to be revealed...

Plot
After the Ice Climbers stole Ivysaur and Squirtle, PT looked around for their pokeballs in the basement. Roy comes down into the basement and offers to help PT look in exchange for joining the team if Roy finds them.

PT accepts Roy's offer despite being coated in blood but Ivysaur and Squirtle have been missing for about a week by this point and he's getting kind of desperate.

Once Roy comes back with the Pokeballs, PT fulfils his half of the bargain and joins Roy.

History
He was born in Kanto to a mother who don't know how to parent. Because of this, her husband left her to go fight in the war and people say he got his own Gyrados to drown a huge group of enemy soldiers, but he also drowned in the process. Idiot. Anyway, at the age of 11, he robbed Professor Oak and trained his pokemon till he said 'Good enough' (But the professor later tried to mug him of his victory money as revenge). He then killed Ash and stole Ash's invitation to smash. So to make it seem like he was Ash, PT used the Magikarp of the gods to steal Ash's soul so he could use it to make himself sound like Ash. It worked great. Then Charizard went rebel and took PT, Squirtle and Ivysaur to the Cut house. And he's been there ever since...

That is until joined Roy to infiltrate the mansion.
