Death Cock

Death Cock was an OC that was originally created on Dragon Ball Hyper as a parody of OCs with conflicting character traits. For some fucking reason, he became an actual character on Dragon Ball Ultimate.

DBH
Cast out of Arcosian society for being too dangerous, he lives in the tundra killing all passerby.

DBU
Death Cock doesn't have much of a backstory in DBU. He simply came to Linux and became the reigning champion of an underground fighting ring. That was until he was beaten out by Brisk. For a short time, Death Cock had no more money coming in from fights, making him just some bum living on the street. For a while, he just accepted his place in irrelevancy and poverty. He was brought back as champion a couple more times, then, out of the blue, he just decided to get up and dust himself off. He left to the outskirts of Linux and became a sort of civil servant, helping strangers to atone for sins of the past.

DBH
Death Cock was described in his original submission as one that "hates everyone, including himself" and that he "kills anyone and everyone he sees, without reason, but tries not to pick fights". This has led to light theorization that Death Cock may be Bipolar, but there have been no confirmations.

DBU
Death Cock's personality becomes much more fleshed out in DBU as he becomes an actual character. He originally started out very boastful and overconfident, but when he was defeated in the ring he went through a bout of depression. This led to him becoming much more of a humbled and considerate person.

DBH
The pinnacle of min maxing. The lowest possible strength and defense without being disabled and the max ki he could have. He only knew how to shoot lasers out of his eyes.

DBU
Death Cock's stats are more equally spread between Defense and Ki. He uses ki barrage attacks that are meant to hit enemies multiple times.
