Ophanimon Falldown mode vs darkrai

Who will win?

info for ophanimonhttp://digimon.wikia.com/wiki/Ophanimon

I'm not too familiar with Ophanimon's feats, but as a Mega Level digiomon she should be well above what most legendary pokemon are capable of.

Does that version of Ophanimon even have feats?

This version is from the game, don't know which one, nor have I played any of them. So this version can only be judged by her abilities.
