Onslaught is like Proffessor X power fused with Magneto body (I think I read chunks of the storyline) He was very big and powerful. it took a ton of heros (Xmen, FF, avengers) to kill him. Parrallax was Hal Jorden. He went insane when his home town and it's people where killed by Mongul and Cyborg Superman. He stole all the Green Lantern power and became this super evil super powerful GL dude calling himself Parrallax. Parrallax and Onlaught are like super powerful guys. I 'm going with Onslaught because it took more to take him down. Though I hope Onslaught comes back someday. Stranger events have happened. 😆 😆
we are forgetting that onslaught also had the full power of nate grey and some power of franklin richards{both of whome he absorbed into himself} and parallex didnt just recreate the universe just like that, he created a whole plan that would lead to the recreation of the universe.
also whoever thinks that onslaught is a pushover compared to parallex is sadly mistaken
u al fall to see one thing. onslaught is a telepath, probably the most powerfull telepath ever, and yes paralax is very strong, but his mind is rather unstable, and onslaught could win this withour throwing a punch.
paralax did destroy the DCU, but i doubt that there is a telepath as strong as onslaught in DC
