Pokémon Model Ripping Project

[The 100 Mega Shock!]

Hello to everyone ripping here! I know it's Final Exam time so everyone is super busy, but I have a few questions that I would appreciate to be answered.

1: Are these models technically "hacked" as they are ripped from XY/ORAS?

I don't understand what you mean by this. It's a copy of the game data converted back to a standard 3D format.

2: Which file from the download for each mon works for Maya? (if there is one)

FBX files are an Autodesk format so they produce the best results when imported.

3: Can I animate in Maya with these models?

Yes, but you will benefit from recreating proper animation controls and FK/IK setups yourself.
