I decided to draw my take on Mammon's design based on the teaser the Helluva Boss twitter account posted a while ago: https://twitter.com/IMPmurderpros/stat…
I think I'm already gonna love this greedy aussie clown cunt. I'm super proud of how this turned out! Helluva has been such a crutch for my mental health for some reason. I can't wait to see the next episodes. ESPECIALLY more of Fizz and Ozzie (my absolute faves)!!! And I'm curious for Mammon of course as well :> It's a great show and I would recommend it to anyone who loves fucked up adult cartoons.
