The Top Ten

2Gorebyss - "Although Gorebyss is the very picture of elegance and beauty while swimming, it is also cruel. When it spots prey, this Pokémon inserts its thin mouth into the prey’s body and drains the prey of its body fluids." - Pokemon (Alpha) Sapphire
So Gorebyss can suck your fluids out of prey's bodies. Not even the most violent animal I've seen does that. O_O - NikBrusk
3Gengar - "Should you feel yourself attacked by a sudden chill, it is evidence of an approaching Gengar. There is no escaping it. Give up." - Pokemon SunGengar, known in Japan by the same name, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise.
4Spoink - "Spoink bounces around on its tail. The shock of its bouncing makes its heart pump. As a result, this Pokémon cannot afford to stop bouncing—if it stops, its heart will stop." - Pokemon (Omega) Ruby
5Mega Salamence - "Anyone standing in its path gets sliced right in two, while this Pokémon continues its flight without interruption." - Pokemon Sun
6Drifblim - "It carries people and Pokémon when it flies. But since it only drifts, it can end up anywhere." - Pokemon Pearl
I want my mommy
7Shedinja - "Shedinja’s hard body doesn’t move—not even a twitch. In fact, its body appears to be merely a hollow shell. It is believed that this Pokémon will steal the spirit of anyone peering into its hollow body from its back." - Pokemon Omega Ru
Not only is this Pokemon completely immobile to the point where it doesn't even breathe or move, but like Gorebyss, it sucks the life out of you, this time if you look at it behind its back. - NikBrusk
8Primeape - "It has been known to become so angry that it dies as a result. Its face looks peaceful in death, however." - Pokemon Sun
No explanation needed for this one either. - NikBrusk
9Honedge - "If anyone dares to grab its hilt, it wraps a blue cloth around that person's arm and drains that person's life energy completely." - Pokemon Y
10Hypno - "It carries a pendulum-like device. There once was an incident in which it took away a child it hypnotized." Pokémon FireRed
It carries a pendulum-like device. There once was an incident in which it took away a child it hypnotized, only me says this is scary.
Such a cool Pokémon, but this really creeps me out... - Entranced98
11Pangoro - "It boasts superb physical strength. Those who wish to become Pangoro's Trainer have no choice but to converse with their fists." - Pokemon Sun
Unless you evolve Pancham, you have no choice but to fight a Pangoro if you want to become its trainer. Not just a regular Pokemon battle, but an actual, physical fight. Not as disturbing as it is violent. - NikBrusk
12Kabutops - "With sharp claws, this ferocious, ancient Pokémon rips apart prey and sucks their body fluids." - Pokemon Silver
