Here’s Dr. Hans Sans Panzer, 17 years before the events of the comic strip. He’s one of the most accomplished scientists in history. He was also part of an all-star team with Ella Pawman and Madison Waltz. Dr. HSP studied toon physics… but the answers he got drove him mad.
As of right now, this past version of Dr. HSP has cameo'd in JPS, Comic #49 and #50
