We're doing a thread of OC's??? Boy, have I ever wanted a forum topic like this... unfortunately, I have like a 50+ character backlog consisting of Fanmade Fire Emblem Units, Fakemon, Fakemon Trainers, Fanmade Robot Masters, and a whole lotta other chicanery. I won't send them ALL but I'll drip feed them to you as I see fit...
For starters, let's make like Regigigas and make a Slow Start. Here is Tanuki Man. My first Robot Master, Created on June 2023 (ignore the date on the picture). Yes this is clearly based on Tanuki Mario. And we can never have a shortage of Animal Robot masters!
