Sora can cast three different magic spells from his Kingdom Key Keyblade - Firaga, Thundaga, and Blizzaga - in a fixed rotating cycle in that order. Each time a spell has been cast, it will automatically shift into the next spell in the rotation; this is signified on the HUD during a match, as it will show which ability is on stand-by. Due to its fixed nature, it will mean that the player must go through the cycle if a specific spell needs to be cast (i.e. to access Thundaga, the player must perform Blizzaga and Firaga first). All three can be Reflected, Absorbed, or Pocketed.
Firaga is a large fireball that Sora will shoot straight out of the Keyblade directly in front of him. He can continuously fire them if the Special Attack button is pressed multiple times in rapid succession or held. It has the longest range of the three.
Sora will raise his Keyblade in the air, which summons three lighting bolts from above to strike the ground below in front of him (similar to Pikachu and Pichu's Thunder). It has the widest range of the three, but this can vary, as it has a much smaller area to cover if Sora performs the spell in the air compared to when on the ground. If reflected, the thunderbolt will bounce straight up.
Sora will fire ice magic from his Keyblade directly in front of him in a fan-shaped spread. As it is an ice spell, it can freeze opponents for a short period of time; however, this can only happen if the opponent is close to Sora, as if they are hit from a distance it will only do miniscule damage. It has the smallest and narrowest range of the three.
Magic is basic ability almost all characters in the Kingdom Hearts franchise can perform. Like with any JRPG, they will require the use of MP (or cards in Chain of Memories), meaning spells will be rendered unusable if a character has depleted all MP that was available to them. Like in the Final Fantasy series, basic spells can upgraded into more powerful versions once a character has gained enough power (either through hidden means, puchasing in shops, or crafting with recipes); this is signified by the addition of the "-a" (Level 2) and "-aga" (Level 3) suffixes to the spell names. Sora uses the final upgraded versions of Fire, Thunder, and Blizzard for his neutral special in Smash; they are three basic spells Sora often learns fairly early into the games' stories.
Firaga is the fully upgraded form of Fire. Its depiction has varied throughout the series; while usually a fireball that can home in on enemies, Sora instead uses it as a protective barrier around him in Kingdom Hearts II, while in 358/2 Days, Roxas fires it into the air in a wide arc where it explodes upon landing on the ground. In 0.2 Birth By Sleep -A fragmentary passage-, a far more advanced Situation Command form called Firaja can be cast by Aqua if she has performed Firaga multiple times; she will fire a much bigger and powerful fireball. In Kingdom Hearts III, another Situation Command form called Firaza is introduced, though produces a similar effect to Aqua's Firaja.
Thundaga is the fully upgraded form of Thunder. When performed, a series of lightning bolts will rain down, hitting a large group of enemies. In 0.2 Birth By Sleep -A fragmentary passage-, a far more advanced Situation Command form called Thundaja can be cast by Aqua if she has performed Thundaga multiple times; the spell calls upon far more stronger lightning bolts to strike opponents in a ring surrounding her. In Kingdom Hearts III, another Situation Command form called Thundaza is introduced, which creates a bigger lighting storm.
Blizzaga is the fully upgraded form of Blizzard. Unlike in Smash, it does not freeze opponents, as it only has Sora firing a large shard of ice at enemies in a straight line. Roxas' version differs, however, as it is homing spell that will attack a targeted enemy after a small delay. In 0.2 Birth By Sleep -A fragmentary passage-, a far more advanced Situation Command form called Blizzaja can be cast by Aqua if she has performed Blizzaga multiple times; she will fire a giant icicle with a wider radius of effect, as well as actually freeze opponents unlike Sora and Roxas'. In Kingdom Hearts III, another Situation Command form called Blizzaza is introduced, though produces a similar effect to Aqua's Blizzaja.
