Hatchiyack (ハッチヒャック, Haccihyakku) is a supercomputer created by the Tuffle genius Dr. Raichi. Hatchiyack is sentient, and is able to collect the hatred of those who die violent deaths, and resurrect them endlessly as Ghost Warriors.
Hatchyiack's Ghost Warriors were summoned by Raichi during his fight with Prince Vegeta.
Hatchiyack broke free from Dr. Raichi's crystal ball after Gast Carcolh destroyed it. After he appeared, he released an ear piercing sound of the collected deaths of many Ghost Warriors, causing the crowd and the participants to hold their ears shut in pain.
After Gast found his weakness, Hatchiyack was reduced to ashes and fell into pieces, most likely being dead.
It is currently unknown how powerful Hatchiyack truly is, but it is possible he is stronger than any of his ghost warriors produced (LSSJ Broly, SSJ3 Vegeta, etc).
Flight: The ability to levitate by manipulating one's own ki.
Revenger Cannon: A devastating energy wave and seemingly Hatchiyack's most powerful attack.
Originally, Hatchiyack was simply a supercomputer that was connected to multiple orbs in his original universe.
This form was the form Hatchiyack took in the most during the multiverse tournament. In this state he was used as a medium for Raichi to summon his Ghost Warriors, or to absorb more hate energy. Riachi constantly set on it throughout his appearances.
When his orb finally cracked, energized hate energy materialized a body for Hatchiyack to fight in. Here he becomes a serious match against Gast Carcolh.
