true, but bishop has mentioned that the xmen were like legendary heroes so they were talked about enough, maybe not as deep as techniques but he would know of them and their skill
thats beside the point though, if bishop cant absorb either of their energies i still think he has a chance, havoks power isnt absolute and wont knock anyone out so easily, cyclops power is concussive but i dont think bishop would go down with one blast
if bishop cant absorb havoks power can he absorb cyclops power
