The monster Rafflesia uses the Charm ability. Charm forces an ally to attack other members. This is one instance where physically attacking the victim does not remove the status. The boss Chadarnook uses this ability as well.
An inverse of this spell is Love Token where the victim does not fight for the opposing side, but instead uses Cover on them. In the Advance version Charm was changed to Entice.
Charm is the fundamental ability that temporarily tames a monster to the caster's side for Beastmasters in Final Fantasy XI. It is also the name of a status effect used primarily by a select few enemy notorious monsters. Beastmaster's charm ability can only work against certain natural creatures (generally animals, Goetia, and avians) but Bards have a version of charm, albeit weak, in a high level spell called Virelai.
Charm also describes a status effect that can be placed on a player character and is available only to a very limited number of creatures including certain very high level Orcs, Merrow, and Poroggo - albeit in the case of Poroggo the normal status effect will not appear as a charm but instead as a costume, but the player will nevertheless fight on behalf of the frog-man.
Charm can only affect units that are of the opposite sex as the caster. Both genders may also affect monsters with charm. Physically attacking the victim clears the status. Thieves use the ability Steal Heart to inflict charm with moderate chance of success. Assassins Celia and Lettie use Allure to charm a male party member, with possibly 100% or less chance of success. Invitation makes enemies fight for you and after the battle, join you, regardless of their sex was a skill of an Orator was changed to Entice in the War of the Lions port.
