So basically I decided in your "Customize character" part, there will be the choice to change races. (Races are above)

Basically I made this final boss for retro city....

Tower of dio (boss rush)

cowboy sans ( against heartale_sans )

Bigger is better right?

added HeartTale True!fresh sans

ill give out this character for those who join the game on date of release, so far this is its ultimate move, and needless to say after the time it can only be given by trade. (Fullscreen to see)

So I was just creatively scribbling for ideas and I ended up with this...

Not my best work but im proud of it :D

Tbh I think this couldn't get any worse
