The second oldest of the five Zaoldyeck brothers, he is obese and a big-time otaku. He himself states that he does in fact assassinate people, so it can be assumed that he is also trained in fighting and is stronger than the average human. Still, he is probably the weakest of the five brothers. He, along with his mother, are wounded by Killua escaping the house. Milluki excels in inventing new types of weapons. He has only left his house twice, with the second time being to York Shin City to buy Greed Island at the auction. This fails and disappointed he heads home again.
