Image inducers were a lazy plot device in the X-Men, specially in the late eighties or whenever Chris Claremont was at the wheel. The non-human-looking mutants (like Nightcrawler or Beast) would go out in public looking like normal humans while using them and have perfectly normal outings. Of course the image inducers failes at the first sight of an evil mutant, random happenstance, or when the story called for them to be angsty.
ANYHOW. The internet is evil. Leopold is a quite obvious amalgam of Dr. Jumba from Lilo and Stitch and the Predator. I had to dig up some image references to do the design. Guess which one yielded porn.
