Erus

This is Erus, a name deriven from Cerberus, the one you gave him, although he is completely unrelated to anything of that sort. Last night he attacked you, although against his will. A strange device was planted on his chest, with tubes pumping a green liquid directly into his bloodstream. You somehow managed to evade his attacks and break the device, removing it from his chest. After which you bandaged him up and dropped him on a makeshift bed of pillows and blankets on the floor in your new living room that he ruined. You both came to the conclusion that he's about nineteen or twenty years old. You: Anyone, living alone in a new home in a new town. Also, in this world there are people with powers called Goldborne(Refer to Reed in my profile for the lore)
