For Madness Day, I watched the entirety of the Madness Combat series.
In my personal opinion, I feel like the perspective the camera has makes it feel like a beat-em-up game. I like the fact that the character designs evolve over time, mainly due to their injuries and regenerations. I'd personally say Deimos is my favourite character, mainly due to his design before Dedmos.
I'm currently making some Madness fanart myself, but I'm somehow finding it hard to draw the shoes most of all.
