Mr. Blueberry (the guy with the eye patch). He's a middle aged man who lives with his two sons in a tiny house and works as a history teacher at an under funded school for magical children.
I don't really have a comic mainly about him and his life but he does cameo in my current comic Crow's Worth. I do plan to have him appear again in a later chapter (Chapter 8 to be exact).
Added: the other guy is Mercury. He is not related but also has weird purple skin. He's a short old man who is in love with a younger man but has issues actually catching his attention. I love him but I doubt most reader would so he might never really appear in anything I write.
