A Fusion Spell is a type of spell in the Megami Tensei franchise that involves the combination of two or more skills, or the powers of two or more personas, acting at the same time, resulting in the creation of unique skills that often have special effects or produce amplified versions of the skills used to form them.

Persona 2: Innocent Sin

Main article: List of Persona 2: Innocent Sin Fusion Spells

Fusion Spells in Innocent Sin are spells activated by having different party members use certain skills or types of skills in a specific order during the course of a single round of battle, which results in moves with unique effects, or moves with an output that resembles a more powerful version of the skills used to create it. Fusion Spells are only usable in battle and in order for them to succeed all participants must be alive, cast their respective skills consecutively (although enemy turns do not interrupt the process), and cannot be affected by a status effect that would prevent them from using their persona that turn. A comprehensive list of Fusion Spells found in Persona 2: Innocent Sin can be found here:

Persona 2: Eternal Punishment

Main article: List of Persona 2: Eternal Punishment Fusion Spells

Fusion Spells in Eternal Punishment function generally the same as they do in Innocent Sin, with the requirements for Fusion Spells to occur being identical, as well as the behavior of the majority of spells. Some spells, however, have adjusted or modified "ingredients" that differ from Innocent Sin. A separate list of Fusion Spells in Persona 2: Eternal Punishment can be found here:

Persona 3

Main article: List of Fusion Spells (P3FES)

Fusion Spells in Persona 3 and Persona 3 FES act as special moves with unique names that are performed by combining the power of two personas at the same time during battle. Only the protagonist is capable of utilizing fusion spells and to do so requires two compatible personas to be in the users stock, and to have one of them equipped during battle. When the requirements are met, the Fusion Spell will appear as a skill in both personas move set, only visible during battle, and can be used at any time at the cost of SP. Oftentimes, compatible personas will have a shared theme or reference other Megami Tensei material, such as the Jack Bros. When activated, an animation will play displaying the protagonists' character portrait, as well as the respective persona portraits, before the move is used. Fusion Spells typically have a wide variety of possible effects and a list of Persona 3 FES Fusion Spells can be found linked immediately above.

Persona 3 Portable:

Main article: List of Fusion Spells (P3P)

Fusion Spells are activated by single-use items that correspond to a given spell, and Fusion Spell items can be used any time by the protagonist via selecting them in the item menu exclusively during battle. Because Fusion Spells are items, the two personas typically required to cast any given Fusion Spell are not required to be in the users stock, and using them does not cost any SP. Despite this, the same animation will play as in Persona 3 and Persona 3 FES before a spell is used. Fusion Spell items can be acquired in a number of ways, such as trading gems at the Antique Shop in Paulownia Mall, or via Vision Quests in Tartarus. A list of Persona 3 Portable Fusion Spells is linked immediately above.

Persona 3 Reload:

Main article: List of Theurgies

Fusion Spells function similar to the original rendition of the game, however, both personas no longer need to be in the users stock, instead, they only need to have been registered to the compendium. Furthermore, Fusion Spells can no longer be used at any time and usually do not cost SP. Instead, Fusion Spells require the use of a full Theurgy gauge, and posses unique animations for each individual spell. A list of Theurgies is linked immediately above.

Persona 4

Fusion Spells make a slight appearance in Persona 4 as an evolved form of Follow-Up attack between two compatible party members that may occur after an All-Out Attack fails to defeat all enemies on the battlefield. Each Fusion Spell has a unique name and requires two specific party members to both be in the party at the same time, however, each Fusion Spell has the same and equal effect, serving as an extension of damage to the previous All-Out Attack. Any of the following Fusion Spells can occur under these conditions so long as both people are on the battlefield:

Twin Dragons: Chie Satonaka + Yukiko Amagi

Junes Bomber: Yosuke Hanamura + Teddie

Beauty and the Beast: Kanji Tatsumi + Naoto Shirogane

The protagonist does not share a Fusion Spell with any members of the party.
