Forsaken

Forsaken, also known as Goner and Forsaken Null , is a recurring ability in the series. It is often the ultimate attack of Kefka when in god form.

Final Fantasy VI
Forsaken is an enemy ability used by Kefka in the final battle of the game in the original versions, and also by Omega Weapon in the Advance and iOS/Android versions. It is Kefka's most powerful attack, with a spell power of 220, and deals unblockable non-elemental magic damage to the entire party at the cost of 20 MP. When charging up the attack, Kefka will say, depending on the version, "The end comes... beyond chaos..." or "The end draws near...", followed by an icon depicting his laughing head, and then the screen will quake.

Dissidia Final Fantasy
Forsaken, called Forsaken Null in battle, is a HP Attack for Kefka. Both the ground and aerial versions are learned at level 38 for 300 AP, requires 40 CP to equip (20 if mastered), have Ranged High priority, and can induce Wall Rush. Forsaken can track the opponent and can be released at any time while charging it, but Kefka is unable to move while using the ability.

Kefka will also use Forsaken as part of his EX Burst, which activates when the button sequence is inputted incorrectly.

Dissidia 012 Final Fantasy
Forsaken returns as a HP Attack for Kefka, now called Forsaken Null everywhere. Both the ground and aerial versions are still learned at level 38, still have Ranged High priority, still induces Wall Rush, and still tracks the opponent. However, Kefka can now move while using the move, the ground version costs 130 AP to master while the aerial version now costs 150 AP to master, and both abilities now costs 30 CP to equip (13 when mastered).

Forsaken also returns as part of Kefka's EX Burst, and is performed exactly as in the previous game.

Final Fantasy Dimensions

Etymology
Forsaken means to be abandoned or deserted. In addition, Goner is a slang term meaning someone is about to die (ie, "he's a goner.")
