SCP Foundation

So what i am thinking is some kind of humanoid entity, who can open a pocket dimension. He uses this to teleport to sick/injured people and pull objects out of. It will then attempt to cure/heal it, And fail cause it doesnt know how to heal people. It will then go into a rage mode and kill the patient in anger. The back story im thinking of perhaps like a doctor in the past before modern medicine who had an anger problem tried to cure a patient of something but he failed and killed them out of anger, then he proggresively got worse and worse until it drove him crazy, then he got his powers somehow and repeats the cycle of trying to cure patients then killing them when he cant

Ehhh. Do you really need all these abilities? You've got:

• pocket dimension
• teleport injured/sick
• pull objects out of pocket dimension
• rage mode (seriously, this in itself will garner downvotes. "Rage mode" is a super-silly term, not to mention unprofessional and way, way ubiquitous in video games.)

I don't understand how the story of an angry doctor relates to getting a pocket dimension. Also, there's no such thing in modern medicine as "healing" people instantaneously, so far as I know.

Humanoids are actually pretty difficult to write successfully; if you're really set on writing one, then take a look at this handy guide.

Sounds like a mix of 049 and 106
