Pokémon (post-original anime series, Domino's take)

This is my take on the Pokémon anime, starting all the way at pre-Advanced Generation era.

Changes

 * The character designs remain in the original 1997 style.
 * The core cast would still consist of Ash Ketchum, Misty Williams, Brock Harrison and Tracey Sketchit, although with some tweaks to their personalities.
 * Ash shows more maturity and intelligence in the Black and White era.
 * He wouldn't be rude towards his traveling companions.
 * Misty is rather more mature since she would act more professional towards Ash and she would be more protective towards her friends.
 * They would keep their same outfits in the original series era.
 * Same goes for May in Ruby and Sapphire and Flannery in Poetry Commotion!.
 * While newer characters like May and Dawn still join in the main cast, they wouldn't replace Misty, Brock and Tracey at all.
 * Iris and Cilan wouldn't join in the main cast, being their rivals instead.
 * Mr. Moore, Daisy, Lily and Violet become recurring characters.
 * The "Dara Da/Who's That Pokémon?" segments would still be used.
 * YTV would still air the anime in Canada rather than moving it to Teletoon.
 * 4Kids would still handle the English dub until 2017 as the entire voice cast is still kept.
 * Cartoon Network and Boomerang would still air the anime in the United States instead of moving it to Disney XD and Netflix.
 * The Black and White era would be more successful.
 * Ash, Misty, Brock, Jessie, James and Meowth would join in the Super Smash Bros. series starting with Brawl.
 * They are later joined by May and Max, Tracey, Flannery, Drew, Dawn, Kenny, Clemont, Serena, Bonnie and Wobbuffet since Ultimate, which also would've added Waluigi and Shantae in order to let them join.
 * The anime would end on the XY era with the series finale about Ash actually winning in the Pokémon League Championship, and the 20th movie was heavily tweaked as it takes a new plot and serves as a proper finale where Ash finally becomes the Ultimate Pokémon Master.
 * Sorrell and Verity have been wiped due to mainly seen as cheap copies to Brock and Misty.
 * However, Liko and Roy would still exist as new main characters in the standalone sequel series Pokémon Horizons.
