Chaotic PKs

Chaotic PKs are the most notorious and skilled Player Killers in The World R:2. These PKers are placed on a special blacklist and other players can attempt to kill them for bounties. During his PK Tournament Sakaki recruited several of the Chaotic PKs and set them against Team Haseo in the first round. However Haseo was able to defeat them and continued on in the tournament.

The Blacklist
The numbers list what order they will show up in the blacklists. Anything other than a number shows that the PK shows up in a non-blacklist event.

.hack//LINK
Chaotic PKs return in .hack//Link as a group of villains. The group is led by .hack//SIGN villain, Kaochin, who was obsessed by lady Subaru's appearance matching hers. Most of the PKs that fight alongside Kaochin are PKs that appeared in .hack//G.U. as Chaotic PKs themselves. The team comprises Cervantes, Gerango, Ibaku, and Pokotan.

Gabi appears as a Chaotic PK as well, but doesn't seem to be in league with Kaochin, whether he and Kaochin are allies or enemies has yet to be revealed.
