then i've no idea who his father is may be his father died in war
or his father is giovanni and the giovanni of team rocket is an incomplete clone
or may be ash's father died and ash never knew who his father was and never bothered to ask
I was planning a Team Rocket fan-fiction where Giovanni is double crossed by one of Team Rocket Commander who take over the organization.
Giovanni's loyal follower brought an injured Giovanni to Delia for help .
It turn out that Both Delia and Ash's father was a good friend of Giovanni until he drift away from them.
Ash's Father is dead and it was the trigger that turn Giovanni into a Bad-guy.
Ash refuse to help Giovanni but later accept his help after The New Boss of Team Rocket tries to take over Kento.
Various character from previous anime such as Misty , Brock , Gary , Giselle , AJ , Richie etc join the fight.
After they take down the new Boss , Ash & Giovanni has a one last battle to decide the fate of Team Rocket.
During the Battle , Giovanni has flashback of his younger days when he had other dream , met Delia & Ash's Father , gone on crazy adventure with them.
There will be a scene of Giovanni & Ash's father fist dumping as Ash defeat him. Giovanni realize his dear friend still exist in Ash.
Later he is visited by the Ghost of Ash's father who tell him to move on and start a new life.
Giovanni shut down Team Rocket and goes on journey to collect information about Ground type Pokemon while hoping to find his Son someday.
Jessie & James become clueless about what to do now that Team Rocket gone But Mewoth remind them that Team Rocket will exist as long as they exist.
So They decide to build their Own Team Rocket and end the episode shouting "Team Rocket Forever"
