A long time ago, before I even planned how I was doing Volume 1, I had a character envisioned at Enzo's school, Professor Watts (get it? electricity.. har har). I drew him WAY back in 2015 as a basic concept, but he was a minor character. However, he still played a role in the story, and still does in Volume 2.
Soooo... after almost 5 years, I took a crack at him a second time. I wanted him a bit stockier, have some Persian influences, and be a quirky fun loving science teacher goof (cues from the tie). He acts not as just a teacher, but a good mentor and friend of Enzo's as well. Even as a minor character, I want to treat every design as something equally important, as it helps me grow as an artist.
Anyway, here's Professor Watts. It's probably very close to the final design for the next book.
