Final Fantasy V
This game was the first to utilize Blue Magic. It also has the most Blue Magic spells of any single-player Final Fantasy game so far, with thirty. Blue Magic is learned in this game when the Blue Mage is struck with a learnable spell.

Final Fantasy VI
Blue Magic, called Lores, are Strago's specialty. Unlike Blue Mages in Final Fantasy V, Strago only has to see an enemy magic used in order to learn it. This means that in addition to enemies, Gau and Relm can teach Strago Blue Magic by using Rage and Sketch, respectively.

Final Fantasy VII
The Enemy Skill Materia functions just like the Blue Mages from Final Fantasy V. Once equipped with it, any character hit by an enemy skill will learn it. However, only that piece of Materia will keep the skill.

Final Fantasy VIII
In Final Fantasy VIII, Quistis can learn Blue Magic from special items dropped by enemies. Quistis can only use the spells with her Limit Break.

Final Fantasy IX
The character Quina Quen learns Blue Magic. S/he learns it by "eating" his/her opponents when they have less than 12.5% (1/8th) of their max HP left. Eating the enemy may teach Quina a new ability, if the enemy is one who can teach him/her one. When s/he is in Trance, s/he can use the 'Cook' ability, which means that it can eat opponents that have less than 25% (1/4th) of their max HP left.

Final Fantasy X
Blue Magic is Kimahri's Overdrive. In order for Kimahri to learn Blue Magic, he just has to perform Lancet on the enemy with the spell. Once he does, he will permanently learn it, and his Overdrive meter will fill.

Final Fantasy X-2
The Gun Mage Dressphere can learn enemy's skills from enemies via the Blue Bullet ability.

Final Fantasy XI
Blue Magic is used by the job Blue Mage. It is also a type of magic ability that players must learn or skill up in order to use effectively. Blue Magic abilities are cast off of the Blue Magic ability attribute, rather than Enhancing Magic, Enfeebling Magic, Divine Magic, Dark Magic, and Elemental Magic. Final Fantasy XI contains the most Blue Magic spells of any Final Fantasy, with over 100 spells at the Blue Mage's disposal.

Final Fantasy Tactics
There is no Blue Mage Class nor Blue Magic in Final Fantasy Tactics, however a few spells can only be learned "Blue Magic style". The spell Ultima can only be gained when it is used on Ramza or his sister Alma in Chapter 4 (or earliest Luso in Chapter 3, but only in the War of the Lions remake). A greater form of Ultima can be learned by Alma during the battle with the final boss Ultima. Any character can learn spells such as Thundaja and Firaja from having them cast on them while they are a job that learns it (i.e. a Black Magic spell can only be learned "Blue Mage style" if the target is a Black Mage), but this usually only applies to the "-aja" tier spells, and a majority of Summon spells. The last spell is the Summon Zodiac can only be learned when it is used on a Summoner during the battle with the optional boss Elidibs.

Final Fantasy Tactics Advance
Blue magic can be used by Blue Mage, a job only available to humans.

Final Fantasy Tactics A2: Grimoire of the Rift
Blue Magic returns as "Blue Magick" and is only usable by Humes.
