Joker's Death (ジョーカーデス, Jōkā Desu?, lit. Joker Death), also known as Joker Doom and Death Joker, is a recurring ability in the series. It is commonly associated with the Slots ability, being the most undesirable effect in most cases as it instantly kills the party and ignores immunity to Death.
Joker's Death is one of two ultimate abilities of Setzer's Slot command. The combination is the most undesirable effect in Slot, instantly killing all allies while ignoring immunity to Death. The combination is the strongest ability, being able to instantly kill all enemies while ignoring immunity to Death, although a handful of formations prevents 7-7-7. Ironically, Strago can learn Level 5 Death by seeing either versions of Joker's Death.

Death Joker is a possible result of Cait Sith's Slot Limit Break by matching Face/Face/Bar. It is the worst ability to get from the Limit Break, as it instantly kills all allies while ignoring immunity to Instant Death. However, if the battle is a Side Attack, it will only target one side of the party, thus avoiding an instant Game Over if at least one character is alive on the other side.
