Can the Horsemen of the Apocalypse KO Heroes, and do their overflows still happen?

Question

Accepted Answer

Yes, Heroes can be KO'd, but the Horsemen are designed to win by filling the board with Overflows rather than by KOing Heroes. A Hero KO also advances the Apocalypse tracker, and Overflows still place their tokens and Thugs.
