Parasite

Parasite is a villain who previously fought Superman.

Powers and abilities
Parasite has the ability to absorb the abilities of others,both superhuman powers and extraordinary skills. He requires physical contact in order to absorb abilities, and this leaves the victim weak and with flu-like symptoms for some time. He can absorb multiple abilities at once and use them at the same time.

During his time with Haly's Circus, he absorbed the abilities of various performers:
 * Jack Haly
 * Carlo
 * Robin
 * Miss Martian
 * Superboy

Weaknesses
Parasite not only takes on the abilities of people but he also absorbs their particular weaknesses as well. He was defeated because he absorbed Miss Martian's weakness to fire.

Background in other media

He appeared in the DC Animated Universe (Superman: The Animated Series, Justice League and Justice League Unlimited); a successor also appeared in the episode "Epilogue". He also had minor roles in Superman/Batman: Public Enemies and All-Star Superman.
