I will add each character i made to this list.
For now, this is all of them that i found (i also made Megalon, Godzilla, MechaGodzilla, Renamon, Guilmon, Ahul, Bowser, Destroyah, Orga, Buzzsaw Gigan, Megaguirus, Yamata-No-Orochi, Titanosaurus and some other, but their quality is terrible (exept for Orga) and i made them from other characters not by me (but only Megaguirus, Titanosaurus and Godzilla 54 is sprite swaps), so, i won`t add them to list)
Characters made by BaganSmashBros. Credits goes to anyone who made sprites and models i used for them.
First fight - Meta Ridley and M:OM Ridley (M:OM Ridley is avaible for download, check Ridley`s page for him)
Second fight - Giga Ridley (check Ridley`s page for him, boss character with Ridley X roar that can annoy you or make your ears explode) and M:OM Samus
Third fight - Raptors
4th - T-rex and Triceratops
5th - SSBB General Griveous (has attack that may trap his opponent until he is dead that can be used by holding B button)
