Ragnarok

Ragnarok (ラグナロク) is an ability that appears in Kingdom Hearts, Kingdom Hearts Final Mix, Kingdom Hearts: Chain of Memories, Kingdom Hearts Re:Chain of Memories, Kingdom Hearts II Final Mix, Kingdom Hearts 358/2 Days and Kingdom Hearts Birth by Sleep. Ragnarok is a technique that lets the user execute a number of laser burst from the tip of their Keyblade.

Mechanics
In Kingdom Hearts and Kingdom Hearts Final Mix, when close to an airborne enemy, Sora will automatically jump up to the enemy and deliver a series of mid-air slashes. Unlike Sonic Blade or Ars Arcanum, it requires no timing to execute the finisher, Burst, although, depending on when you press the command, a certain amount of lasers will be released; however, it should be noted, the longer Sora charges for the Burst attack on air, the heavier the damage inflicts. To note, the best time to release the most amount of lasers is immediately after the circular burst of light, which shows the lasers are done charging. Aside from that, the lasers fired also have homing capabilities, which target and destroy the nearest foes in sight. Sora can move freely while the lasers home by themselves. It costs 4 AP and uses up 4 MP bars.

In Kingdom Hearts: Chain of Memories, pressing after the initial shot, can fire additional projectiles, but fewer rays are fired if pressed to soon.

In Kingdom Hearts: Re:Chain of Memories, pressing after the initial shot, can fire additional projectiles, but fewer rays are fired if pressed to soon.

In Kingdom Hearts II Final Mix it is only available while using Limit Form, using Ragnarok will trigger a Reaction Command, Burst, has to be hit at the right time for more projectiles to be fired. Hitting too early will cause fewer lasers to be fired. The most lasers will be fired if you press during the third Reaction Command opportunity.

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 conjoined together into a drilling fashion, piercing through enemy guards.

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.

Etymology
Ragnarök 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. Ragnarok is also a reoccurring Summon and weapon that appears in various games in the Final Fantasy series. It also appears as an airship and a legendary beast.
