Mixamo

Mixamo is Adobe's free web service for animating 3D characters: upload a humanoid mesh and its Auto-Rigger builds a full skeleton and skin weights in seconds, then apply hundreds of motion-captured animations (walk, run, dance, fight, and more) from its library. Exports as FBX or OBJ for direct import into Blender, Maya, or Unity, and the popular Blender Mixamo add-on can even push rigged, animated characters straight into a scene. Free with any Adobe ID, no Creative Cloud subscription required.
