Cupze will not hesitate to kill someone, but is always eager to know them first. He loves adventures too. He can seem intimidating on the outside, but knowing him better, he can act a bit silly. He can easily flatter you, as well.
When he was young, his Elder Kettle adopted him and his brother: Mugaoz. They were then joined in a gang, but soon Mugaoz was kidnapped by the enemy gang. They then turned into enemies, fighting eachother but never killing eachother.
