Pratch was originally a murderer who got electrocuted and somehow woke up in Scratch. He forever lives in pain while also causing pain to others. The vessel he's in gives him super strength and world manipulation powers. He can also change his face to anything imaginable. He hates Tera the most.
I used Red's (the godzilla NES creepypasta guy) face as inspiration unrelated note here but Pratch absolutely rocks the piano. also scratch is his own purgatory considering he murders people (bad, right?) Chris Prat(ch)
