Nightmare (ナイトメア) is a character from the anime and manga of Bobobo-bo Bo-bobo. He resides in Hallelujah Land.
Nightmare is a man with orange armor, two spaced buck teeth, and two horns on the sides of his head. As the Guardian of the "Little Kids Area" of Hallelujah Land, he fights by taking advantage of being the only adult within his area. This comes in handy, as Bo-bobo and his group have been turned into little kids thanks to the arenas power; this also cancels out their fist abilities!
Despite this, Bo-bobo fights back anyways, and ambushes the villain with a shark in a sandbox and a bottomless pit. Afterwards, Nightmare is lured into a pipe maze, where Bo-bobo attacks him with a flame thrower, Don Patch attacks him with two pistols, and is blown up by a grenade! Despite all of this, Nightmare survives, and unleashes his most powerful ability, "Death Nightmare"; the ability to make his victims' worst nightmares come to life,... if you call them nightmares that is. Tennosuke's was being tortured by tofu, Don Patch's was being surrounded by seven beautiful women wearing bunny suits, and Bo-Bobo's was playing basketball with a bunch of kangaroos.
Finally Bo-bobo decides that a fusion is needed to defeat the boss, and he and Don Patch try to create BoboPatch. However, due to the fact that they are small children, BoboPatch comes out poorly drawn. Nightmare makes the fatal mistake of underestimating his new foe, and BoboPatch winds up defeating him with only one attack.
