Wow, what a great cartoon! I admit it could have been longer, but it was still amazing. This guy reminded me of King from "The Owl House". It helps that I was just watching that this morning. The animation is obviously fantastic. It seemed like this was telling a story.
It wasn't really just a fight. It was connecting the early experiences in this character's life. That isn't bad for something so short. It was more like a trailer. While it's December, this is great to watch at any time!
