What is the name of an 90's comic book?

The comic book only had a couple made in the 90's. It took place in outer space. The hero was a whale like character, and the enemy was a rhino. This particular comic also had another story on the backside. That story was of robot that used to be a boxer, and was missing one of its hand or glove. I don't really remember to much about that one. It also took place in what appeared to be in the 50's or 60's..something like that. Does anybody remember the name of this comic book?
