Ragnarok

Ragnarok (ラグナロク), known as "Infinity" in Kingdom Hearts HD 2.5 ReMIX, is a special technique introduced in . It allows the user to fire a cluster of energy bullets from the tip of their Keyblade.

Mechanics
In Kingdom Hearts, Ragnarok is a Special Ability. When close to an airborne enemy, selecting the Ragnarok command will cause Sora to automatically jump up to the enemy and deliver an aerial attack combo, after which he will hover while charging energy. Unlike Sonic Blade or Ars Arcanum, it requires no timing to execute the finisher, Impact; however, the longer Sora charges before using Impact, the more projectiles are fired and the heavier the damage, with the optimal time being immediately after the Keyblade releases a circular burst of light. The projectiles home in on enemies after being fired, while Sora can move freely. Waiting too long to use Impact causes the energy to dissipate without releasing the projectiles. It costs 4 to equip and 3 MP to use. Sora is invincible during the initial weapon combo, but when Sora is charging the projectiles, he is left vulnerable to damage.

In Kingdom Hearts: Chain of Memories, Ragnarok is an attack sleight. Pressing, in Kingdom Hearts Re:Chain of Memories, fires the projectiles sooner, although there is no difference in damage. Waiting too long causes Sora to fire the projectiles automatically. Sora can also fly around and adjust his position to aim better if need be. In Re:Chain of Memories, the rays home in on enemies, and letting it charge until the burst of light appears launches the most rays, and Sora takes to the air higher and slower than other incarnations of the attack, and can only aim left and right in the remake. The initial weapon combo from the Kingdom Hearts version of Ragnarok is not executed in both versions. The card combination for Ragnarok is:

In Kingdom Hearts II Final Mix, Infinity is an action ability available while in Limit Form, either from the Limit menu or by pressing in the Shortcut menu. Using Infinity will trigger an aerial attack combo, followed by Sora charging energy while in the air. Executing one of the Reaction Commands that appear, Shoot, Impact, or Giga Impact, will fire the charged projectiles. Waiting until Giga Impact before pressing will fire the most rays. The projectiles home in on enemies. Ragnarok costs 80 MP to use.

In Kingdom Hearts 358/2 Days, Ragnarok is Sora's Limit Break. The Final Limit version fires larger, faster shots that lose their homing ability but are propelled together in a drilling formation, piercing through enemy guards. For both, allowing it to charge before pressing will fire a larger number of projectiles.

In Kingdom Hearts Birth by Sleep, Ragnarok is a Shotlock that has a maximum level of 4 and max lock of 16. Once the attack has begun, the player can perform extra attacks by pressing at the right time to fire additional projectiles.

In Kingdom Hearts 3D: Dream Drop Distance, Ragnarok is a Dual Attack that allows Sora and the Spirits to launch a devastating salvo of light at the enemy.

Etymology
is an event in Norse mythology that is similar to the Apocalypse. It is an event that is set off by the death of the god Balder, which was orchestrated by Loki. The Ragnarok was a final clash of all the major entities of Norse mythology. This caused all of the human spirits up in Valhalla to come down for the final battle. This bloody encounter ebbs with the destruction of the universe and Balder along with a little handful of entities that are put in the bodies of children and only contain memories of the world before Ragnarok. Those entities would become mortal.

is also a recurring Summon and weapon that appears in various games in the     series. It also appears as     and.

Trivia

 * In the first game, when Ragnarok is fired just after enemies are cleared in a room, the projectiles will fly and lock on to a specific spot often out of Sora's reach, as opposed to scattering in random directions.
