Nuclear (核熱, kaku netsu)?, also known as Nuke is one of the elemental affinities in the series. This element only appears in Megami Ibunroku Persona, Persona 2 duology and Persona 5.
In Megami Ibunroku Persona, the line of Frei spells target 1 enemy except for Freidyne, which deals area damage like other -dyne spells. The equivalents of "Mafrei" spells are instead represented by "Megido" spells due to the lack of the non-elemental Almighty Skills.
In Persona 5, damage inflicted by Nuclear skills increases if the target is suffering Burn (inflicted by Fire Skills, replacement of Poison), Freeze, or Shock.

Nova Kaiser from Persona 2: Innocent Sin is incorrectly stated in-game to deal Nuclear + Light damage, but it actually deals Almighty + Light damage. Its Eternal Punishment counterpart, Nova Cyther, does indeed deal Nuclear damage.
