http://www.answers.com/topic/final-fantasy-xii możemy przeczytać, że jest ich o wiele więcej:
" Summoning magic appears once more with creatures known as Espers (as in Final Fantasy VI although the name may change during translation). In order to acquire an Esper, the creature must first be defeated in battle. Afterward, one character must sign a pact with the Esper, and that character will be the only one who may summon it. Unlike any previous Final Fantasy, summon spells cause only two members of the battle party to withdraw from the battlefield and the Esper replaces them to fight concurrently with the summoner. While the Esper is present, the Summon command in the menu becomes the Dismiss command, which the player can use to send the Esper away at any time. The Esper will remain in the party for a limited time, indicated by a row of spheres that gradually disappear over the course of a minute or two. If the Esper survives until the time limit reaches zero and is not dismissed by the player, it will perform a very powerful special attack before leaving the party. The player can use curative magic and items to aid the Esper. Espers are controlled by A.I. and cannot be controlled by the player.
Espers:
Adrammelech
Belias
Chaos
Exodus
Famfrit
Hashmalim
Mateus
Queklain
Shumihaza
Ultima
Zalera
Zeromus
Zodiac
While these have patently replaced most if not all of the traditional Final Fantasy summons, Final Fantasy XII features several airships bearing familiar names, including Alexander, Shiva, Ifrit, Carbuncle, Valefor, Leviathan, Catoblepas, Remora, and Atomos. "
I jak widac nie ma tu nic o Ifricie i Veliusie.
