Hardcase featured in the short lived Ultraverse along with Prime and an assortment of other characters, he had his own series as well as featuring in Ultraforce for a brief period. There was also a cartoon series in the early 90's based on the Ultraforce cartoon.
The best way to describe Hardcase is to imagine the powers of Doc Samson crossed with Captain America. Nearly invulnerable, super strong and a natural leader.
He was a member of a super team called "The Squad" before they were defeated in battle.
Hardcase also featured in the Prime Annual, teaching Prime how to be a "real Hero".
I enjoyed the Malibu titles, and while Galoob did make action figures of Ultraforce, these toys were pretty basic. I truly feel each character is worthy of the Marvel Legends treatment (Marvel now owns the rights to all Malibu characters)
Hard Case was made using a WWE Zack Ryder.
I custom painted the details and used Foamy sheets for his shoulder armor ( Why does a guy who is nearly invulnerable need armor???)
