Cutie marks appear when ponies discover their special abilities. In the case of my adaptation of Attack on Titan that is realistic in terms of character design. So I chose everyone to become a horse based on a real-life breed. No pegasus or unicorns, just horses.
Where there should be a cutie mark, it will be replaced with the unit's symbol. It is based on shaving the horse's hair to create a pattern that can be done realistically.
I think I just like it when a formidable, but soft inside and tired of his burden, a bearded guy suddenly meets a curly-haired gentleman who makes him happy with his cute stupid trinkets and the same cute, stupid words
