Negative Man (Larry Trainer)
1963
for 1963 in Comic Characters by Debut Year
Suggested by emeraldshinigami
This is going off the debut of comic book characters. In the cases of characters who were introduced in other media originally and added to the comics canon later along (ex: Harley Quinn) it'll go by actual debut year.
