If you control a Fusion Monster that must be Special Summoned with "Dark Fusion", you can Special Summon this card (from your hand). You can only Special Summon "Evil HERO Dead-End Prison" once per turn this way. You can send 1 "HERO" monster from your Deck to the GY; if you Fusion Summon a "HERO" monster this turn, this face-up card can be used as a substitute for 1 material mentioned by name, but all other Fusion Materials must be correct. You can only use this effect of "Evil HERO Dead-End Prison" once per turn.
