Yes, it is at 0,0,0 and it is animated. As I said, if you’re looking at mixamo characters (alpha/beta/zeta/whatever), you’re looking at the wrong place.
It is mixamo fuse character. Mixamo fuse is character generator. The bone chain goes like this root->pelvis->spine_01->spine_02->spine_03, etc.
The only problem is that its motion does not transfer during retargeting process. At all.
