Rhino (Marvel)

Aleksei Sytsevich aka the Rhino, was a Russian immigrant who was succumbed to radioactive testing, granting him powerful superhuman strength and durability. He was also given a suit of tough, rhinoceros-like armor and horns for even more destructive capabilities. He has combated Spider-man many times, as well as the Hulk.

Rhino later reformed from his criminal ways, but his identity was taken up by another, unnamed criminal who wore a mechanical suit and became the All New Rhino. The two Rhinos battled, and the original Rhino killed the newer one.
