My answer:
The first game has to pull from stuff till saiyan arc
Using Powerpole, kamehame has and after image technique
With makafushigi adventure playing (would be the dragonabll main theme in this reality)
Meele pulls from everything till the end of freeza
Everything returns
Similar to zelda db would always get kid goku in games (cus dragonballs first half wouldnt be ignored)
Popular cahr that was important during most of What if db and always player 2
Is used as the villain rep because Vegeta is still too new for sakurai
has Chala head cahla Playing
Has mezase tenkaiochi Playing (or a remix of makafushigi adventure)
In Brawl The entirty of dbz Already exists:
Kid Goku and Classic Tournament Are cut A lot of people are sad about this
is added and brings hype
Goku gets spirit bomb, kuririn gets a giant kame hame ha and piccolo gets special beam canon as final Smashes
The Dbz Tournament arena is added
Smash 4 has gt to pull from
Gets brought in as the new Kid Goku
Controversial choice has a similar vibe As the whole shiek is in instread of impa situation!
And finnaly Ultimate has Super (pre morro) to pull from
Kid goku rverses back to his meele/ Classic db Design and classic tournament gets added replacing the z variant
Beerus gets added
because of his recent resaurgance freeza gets added
gets added
