Bullwhip is a supervillain who is able to extract metal whips from his wrists. He got these powers by enlisting the aid of Dr. Corso. Bullwhip seemingly wasn't satisfied enough with the weapons. So, he and his gang kidnapped Dr. Corso's wife April and blackmailed him into making upgrades to his wrists. However, Batman got involved and the gang overpowered Terry the first time. After stalking them to their hideout, Batman and Dr. Corso find out the April wasn't kidnapped, but there willingly. Dr. Corso freaked out and fled. After Batman disabled all his teammates, Bullwhip returned to Dr. Corso asking him to upgrade his wrists again and "don't hold back". Dr. Corso took his drill out and Bullwhip's words literally and proceeded to work on his wrists. Bullwhip's ultimate fate is unknown.
- His Marvel Comics counterpart is Omega Red.
