How do you rip Models

[~DrakoRero~]

So I found out how to take models and textures out of TMNT 2 Battle Nexus ( also the soundeffects, look foward to that! ), however they're not in their T-posed, what do you do to make the models in a T-pose to deem them usable, I'm a amateur at modeling .

here is Drako, he's my favorite character, ignore the link name lulz.

I'm assuming the models are missing their bones and are automatically in their game poses taken from DXripper.
yeah they are missing their bones, any solutions would be great c:.
