The Defenders add a new twist to the Battle Simulation Room--a Thought-Transference Cap. It transmits the wearer's imagination directly into the simulation; Kshin loves to use it to scare the other Defenders the best he can. But Ming the Merciless has found a way to tap into the Room. Using his ghastly power source, he can use his own evil thoughts and intensify them into reality! What starts out as a thrilling simulation under Kshin is taken over by Ming and turned into a terrible fight to the death in the all-too-real Haunted World. While the older Defenders fight monsters, harpies and skeleton warriors, the desperate young Defenders destroy the simulator and end the horror.
