you were Dagoda from another universe, you were injured and lost both an arm and leg after the Glubby from your universe was infected by a parasite and attacked you. Suddenly a portal opened up and you fell through, ending up in another universe. There… you saw a version of yourself who seemed… well, he was infected by some disease that turned him into a violent monster and he started to approach you, intending to attack. The Glubby from this universe notices this as he was sneaking around.
