Deal a small amount of lightning damage.


Thunder is a magic spell in Final Fantasy VII Remake and "Episode INTERmission". It is granted by the Lightning Materia Lightning Materia, and is the basic Lightning Lightning-elemental spell below Thundara Thundara and Thundaga Thundaga. Thunder deals a small amount of lightning-elemental damage, but has a minimal MP cost, and a short casting time.

In the downloadable demo, Thunder is one of two magic spells that Barret Wallace can use, along with Cure Cure. Thunder is also a materia in the Fort Condor minigame in INTERmission on the following boards: Sorcerer Board II, Battalion Board I, and Grandmaster Board. The spell damages a chosen target.

Thunder costs 5 MP to cast, and can be cast by those with level 1 lightning materia equipped. The spell has many uses against low-level enemies, and can be used to both deal considerable damage, killing many early enemies, as well as pressuring and staggering more powerful enemies at low levels. Among its peers—Fire Fire, Blizzard Blizzard, and Aero Aero—the main strengths of Thunder are that it is guaranteed to hit its target, and that it can damage enemies weak to the lightning element, such as machines. In Final Fantasy VII Remake Intergrade, wind spells also always hit, however.

Thunder is outclassed by Thundara. Though its low MP cost and short cast time can make it useful in some circumstances, Thundara still hits enemies very quickly and is guaranteed to hit, meaning there is less reason to use Thunder unless short on MP. At level 3, once Thundaga is obtained, Thunder is effectively redundant.

The Thunder spell can be amplified by pairing the lightning materia with Support Materia Support Materia. Pairing it Magnify Materia Magnify Materia is particularly useful, as Thunder is guaranteed to hit all enemies, while pairing it with HP Absorption Materia HP Absorption Materia and MP Absorption Materia MP Absorption Materia can be useful to a character's sustainability. However, these materia are often best used with more powerful spells. Thunder can also be used effectively with Aerith's Arcane Ward to cause it to be cast twice.

In Episode INTERmission, Yuffie can already deal elemental magical damage without MP cost with her Elemental Ninjutsu, and so equipping her with spells is less relevant. Thunder may be more useful on Sonon Kusakabe, or when paired with magnify.
