Primo is the eldest brother, not much to say about him lol. Secondo is the second to oldest brother. Technically a grumpy old man but he can be chill and fun to be around at times. Terzo is th second to youngest brother. He's really suggestive with things and straightforward, short and simple but funny. Copia is youngest. Rats, autism, and video games are three main words for Copia. All once singers in a band, but all take initiative in being in the satanic church.
