PaniK

Player Killer of Darkness (「闇」のプレイヤーキラー Yami no Pureiā Kirā) is a player eliminator hired by the Duelist Kingdom. He appears to be a rather brutal man and as Yugi Mutou and his group arrive, Mai Kujaku (Mai Valentine) has just been defeated by him. In order to salvage the situation and return Mai's Star Chips, Dark Yugi challenges the Player Killer to a duel. Using the power of Castle of Dark Illusions, Player Killer clouds the field in darkness and hides his monsters. Yugi eventually reveals his monsters with Swords of Revealing Light. He then uses Catapult Turtle in conjunction with Gaia the Dragon Champion to damage Player Killer's castle. Although the castle remains after the assault, its flotation ring is destroyed, and as Yugi puts it, the Swords of Revealing Light are the only thing sustaining the castle's flight. After the Swords of Revealing Light expire, the castle falls to the ground, destroying of all of Player Killer's monsters and depleting the remainder of his Life Points. Player Killer then activates the flame ejectors that are in the ring, attempting to incinerate Dark Yugi. However, Dark Yugi is safe due to the power of the Millennium Puzzle and he inflicts a Mind Crush on Player Killer. In the English anime, Panik's soul is sent to the Shadow Realm. Titan, from Yu-Gi-Oh! GX!, is his counterpart. He uses a tactic based not on preventing the opponent from attacking but from targeting his card, he also claims to play the Shadow Game, like Player Killer, a "duel in shadows."
