Here’s a drawing i did a while ago. It’s Mark Grayson (Invincible) and his dad, Nolan Grayson (Omni-Man) from the comic book Invincible as if they were in the Simpsons. The idea came about from my thinking that Ned Flanders may possibly be a Viltrumite.
Oh, and here’s one of Oliver, too.
For the record, and what my two cents are worth, Invincible is the best comic book on the stands today. I highly recommend checking it out.
