The VG Resource

So i went and ripped character models from the Mobile game Winx Club Secret of the abyss and i noticed something wierd, one of the character models of the main cast is properly t-posed
  
However some of the other character models aren't t-posed and are instead in some sort of pose, as if they're in a idle pose....not sure why this happened or if it's something to do with the way i ripped them (the game uses unity engine so i was able to use unity studio to rip them)  this one seems to be in a near A-pose or V-pose. I'm not sure if this is how they're meant to be or not.


Edit: I tried one of the other mobile games and the models rip in a flying pose, and then one of the models is just broken and a bunch of broken, tiny specks minus a few pieces. not sure why it happens to that one specific character model but i can't seem to get it to rip with rigging and not have it do that.
