Milluki Zoldyck

Milluki Zoldyck (ミルキ＝ゾルディック Miruki Zorudikku) is Killua's second eldest brother

Background
Milluki is an obese figure who possesses a strong aversion to performing any kind of physical activity. In fact, prior to the YorkShin City auctions, Milluki had not left the mansion in eight years. He seems to be a sort of otaku, since his room is covered with female figurines from various anime and computer games, as Killua asked him to hack a copy of a memory card from Ging. He was also injured during Killua's escape. Milluki is primarily in charge of torturing Killua as punishment, but doesn't have the drive to carry it out very long as it is exhausting and extreme physical exertion is needed.

After being tipped off the whereabouts of Greed Island, Milluki's excitement resulted in one of the rarer moments in which he made an outside expedition in search of the game. However, he was unable to win a copy and left in frustration.

Nen / Ability
Milluki does not seem to be able to use Nen yet, if any at all. Expert Hacker/ Programmer

Milluki is talented in hacking computer systems, He tried to reverse engineer the game Greed Island using a save data copied from a memory card left by Ging, but was not able to run it in any of his computers, which lead him to the idea to try to hack into the Hunter website but never went with it because of the risks. Inventor

He claims to have invented a micro sized bomb that can be placed on a mosquito that explodes upon being bitten for assassinations purposes, However the bomb's explosion is only as big as a fire cracker's and it's pretty much impossible for a mosquito to bite a target that you want. 糜稽
