Spiritomb

The Second pokemon with no natural weaknesses the first was sableye. In the dex entries it is said that it was punished for all of its crime and sealed in an odd keystone, and it also said it is composed of 108 menevolent sepreate yet bound souls, its apeaerence is like a purple swirling supernatural vortex with green eyes and a black spiral for a pupil in its left eye and a nasty set of spooky teeth, around its face are green orbs that orbit around it. The head part is connected to a stone base with a fissure in it supposing it was released when the seal was broken half way but still bound to the stone.

Trivia: Certin trainers actually use this somewhat invunerable pokemon in competitve play, because it can learn hypnosis and dream eater to wipe out its opponent and regenerate itself.

This pokemon might be based on a budhist tradition which involves ringing a bell 108 times to repel 108 temptations in order to achive nirvana, or it may be based on a very rare type of spirit called a legion(multiple spirits or demons to form into one powerful entity) and a spirit called Jibakurei a ghost that is bound to a single place.

The unusual way to get spiritomb is to drop the odd keystone in the hollow tower talk to 32 people underground but people get confused by talking to the miner sprites it ment actual people who go under ground or talking to the same person 32 times(actual people players) and get back to the surface where the hollow tower is and start looking or trade with someone who already has one. Note: those of who tried to breed sableye and spiritomb, they maybe the same type it does not mean they are the same egg group.
