if this has been brought up im sorry. with mk8 using the unreal engine the anamalities could be sick. but have the anamality not be a finishing manuver very similar to the bloody roar series and not have dumb animals for characters.
here are some suggestions scorpion turns into an actual scorpion, reptile turns into a komodo dragon, sub zero turns into a great white shark, raiden an electric eel. there would be a morph bar that every time you do a special the bar would increase then just tap the directional pad up twice to morph. could last for 10 seconds. all animals would beable to fight and walk.
i have more if you like. tell me what you think about having an anamality as not being a finisher but like turning into the animal for a short period of time.
