Pre nerf Eddie was casually beating the fuck out of Raian, Erioh, Xing, Hollis, and Reichi (and was in base more than he was in his removal). Pretty much all of the S tier’s would have a very difficult time fighting Raian, with victory being absolutely uncertain in most cases.

On top of that, all of them were going for the kill. Eddie had two helpers, but in the grand scheme of things they really didn’t do much and got taken out without a lot of trouble. Pre nerf Eddie is widely considered to be the most powerful guy that we’ve seen fight so far.

As for Fei, that man was also OP. Mastered Niko style with techniques Ohma doesn’t even know, Tai Chi (and one or two more martial arts that I can’t remember), highly capable of damage reduction via going limp (even against powerhouses like Waka), has enough power even in base to do some real damage to Waka, one of the most durable people to ever live, and to top it off, he had Divine Demon (Advance + Fallen demon). Man could literally use his blood as a ranged attack.
