Well backstory is easy if you have played the games (I have but not knowing which version of sora you go with could be a bit for backstory). Costumes you could go with KH 1 outfit, KH2 outfit, Dream Drop Distance Outfit, and maybe even kid sora with a wooden sword XD. Movesets you could look at ton that have been on this forum and use different ideas from them (but of course be sure to give credit). I would go into further detail but its a little bit much for me to put into one post XD. Anyway great idea let us know how it goes.
Yes please Do Klonoa!
If you play Klonoa heroes on GBA, he has weapons you wont find in his past games which would come in handy for his moveset.
Klonoa back in the PSone days was the 'only' character that acturly made me cry
Just created a teaser of what's to come. It includes three topics: why Sora should be in All-Stars, story in All-Stars and the backstory of Sora.
Please feel free to tell me what you think and/or should I stop creating this?
