Aleister Ketchum the reincarnator

Aleister was just your usual otaku that loved the pokemon franchise after seeing Ash's departure from the anime and being depressed then finishing the new pokemon game he decided he's going to revisit the game that got him into pokemon The game that to this day is his favorite no matter what any other person says He started playing pokemon fire red again and decided for old times sake he's gonna use cheats again after beating the league and catching almost all the pokemon from kanto and capturing mewtwo in a pokeball after 1562 action replays he gets off his game and decided to get something to drink Only to be attacked by truck-kun on the way after taunting and evading truck-kun and going back to his house thinking he beat the isekai God only to be crushed by a helicopter After that walking up as his character in a mix of the pokemon anime and game more specifically his fire red game But wait why does he have everything from his fire red play through and how is he related to Ash!? *rewrite*
