Here's a short video showing the various animations for the Pirate character from Troublemakers. I rigged and animated it in Blender, back in 2016-2017. (The model itself was produced by someone else). It was from scratch, no rigify. The arms and legs use simple IK. The whole thing is very rudimentary, which is not surprising since I'd never d one animation before. =/ There are additional bones in the skeleton for attaching weapons in-game.
