In two words? We happened. In more than two words, Apocalypse and his Horsemen got taken down by certain mutants of your acquaintance (including the New Mutants girls with Famine, way to go team!) as well as the good people of New York, Apocalypse's power apparently runs off people believing in him and so by the end, he was pretty much beaten before anyone had to lay a punch. Not that that didn't stop some. *wry* Then as Garrison said, he arrested the bastard and he's banged up in a cell for the duration.
