3D. The easiest method is with VRoid Studio, which is free software developed by Pixiv.

2D. Live2D seems to be one of the most popular choices, E-mote (emofuri) is another one though it's in Japanese. I'm pretty sure there was another 2D maker, but I can't remember what it was called.

Both: Next would probably be to build you're own from scratch using Blender, there are a lot of good tutorials on YouTube that can get help you started, and with the upcoming features 2D characters should be a lot easier to make.
