I suspect they had no production photos of Dr. Ball when the comic was being drawn and just winged it. Much like they used one of the background aliens for Jabba. Did they ever make a figure of Marvel Jabba?
Oh, I’m not the least bit surprised at the presence of the green bug-eye droid from the comic, especially considering, as you mentioned, how Jabba turned into a tusk-less yellow walrus in an orange imperial uniform. I just thought it was funny that Hasbro decided to repaint Vader, Tarkin and the Rebel soldier to make them more retro, but instead of copying the comic interrogation droid, they just took a ball-droid and painted it green. I’m surprised they didn’t just take a Death Star Droid and repainted that green. I would assume that is what Chaykin used as reference.
