they won when mindless hulk shattered his shell and a bunch of people entered his "perceptive reality" stage of development, though IIRC, they had a narrow time window to get that done before he grew stronger.
of course, none of them were close to the P5 in power and onslaught's shenanigans only reached the threat level they did because of his ursupation of franklin's powers.
Originally posted by yaadaveyaaabsorbing them is a feat? nate grey was quite incompetent at that point and franklin was a scared child. psionically dominating them doesnt mean he was actually more powerful than either at first.
did u read those comics u did absorb franklin which in it self is a feat and nate... he took out two very strong heralds if onslaught were actaully allowed to win he would have crushed everyone hes just the bad guy hes not allowed
