Bio: Cactus was a cactus-like creature designed by Dominus and consisting entirely of pulp. Over a dozen different Cacti were known to have existed at one point, but many of them were destroyed by the Avengers. Each Cactus could fire needles from its body, and regrow severed limbs. At least one Cactus was later incarcerated at the Vault. The Avengers never considered Cactus a serious threat, kidding it with the line "stick around."
