SCP-5031 is a non-sapient quasi-humanoid creature of unknown origin. When directly observed, SCP-5031 will temporarily cease to exist until the viewer stops observing the space that SCP-5031 formerly occupied. Traces of its existence (e.g. scratch marks, blood trails) continue to exist when SCP-5031 does not. 

He likes cooking and music.

Can sometimes be mean if he doesn't hear the person playing their favorite song, sometimes swearing and calling them a virgin or any other vulgar words.
Can be nice..Sometimes. 

Can be mean, can be nice, depending on the music
