Romulus is a Marvel Comics supervillain. He is originally said to be the leader of the Lupine, a human looking species who, through convergent evolution, would have evolved from canine instead of primates. He is a shadowy character whose origin and motives remain a mystery. He is shown to have orchestrated most major events in the life of Wolverine, manipulating and controlling him for most of his life. After several years of being shown only in shadows, he made his first full appearance in the 39th issue of Wolverine: Origins.

Romulus is first seen in several flashbacks that Wolverine experiences, later explained by Wild Child to have been induced by Romulus himself. He is shown leading the Lupines in prehistoric and barbaric times, being an emperor in Ancient Rome , as well as being the main force behind Weapon X.

In present day, Romulus restored Feral and Thornn's feline look after their depowerment, augmented Wild Child's powers greatly, and erased all humanity from Sabretooth, causing the latter's death at the hands of Wolverine. The exact reasons for these acts remain unknown.

Romulus was also the one who took Daken from his dead mother's womb and raised him as a ruthless killer. Nick Fury revealed to Wolverine that Romulus has been manipulating people from his family's bloodline for centuries, and that he plans for Daken to become the next-generation Weapon X. This was achieved through The Tinkerer, who bonded the metal from the Muramasa blade to Daken's inner claws. Daken hinted he complied with the process because of his own agenda. Romulus told Daken to kill all the Weapon X experiments that gave them a healing factor with his Muramasa claws. He killed every one except Deadpool.

Romulus has not been a contender in any CBUB matches.
