My Idea :
UB Trickster [ Doppelsona ( Doppel : Double, Sona : Persona ) ]
[ Masked Pokemon ]
Dex's Entry [ Full ] :
A very dangerous UB that moves real fast and can hide itself real good. When it got caught in action, it'll act like a nice person, takes the victim to a quite place, play a trick and killed them . When someone found the victim , they are already dead with random cause, like they got frozen to death, burned, electrocuted, etc. But not all of the victims are dead. The survivor described it with a white-black mask-like face, swords-like finger at it's right hand and demonic left hand. It's also have bird-like feet and it have human-like posture. Apparently it likes to collect jewelries and treasures, making it have a thief aura. Nobody knows from which dimension it came from.
