Omega Red is like a vampire. He needs others life force to sustain his own. Hes pretty much immortal. Youd have to lock him up in a steel coffin away from life. He has a high healing factor thats Wolverine level or better. He has excellent fighting skills and with the use of his tentacles, hes about 10-15 class.
Phermones WILL knowck out Rand and Cage and could kill them if they are exposed to if for to long. If they touch him or vise versa, he can drain their life force and kill them as well.
