An Esper of unknown origin. Makes a Shell to protect the party.Final Fantasy VI PlayStation esper section
Zona Seeker is a brown, red and black floating creature. Its body is mostly skeletal and has no legs, while it appears to also wear a cape.
Zona Seeker is a rather useful magicite for the first half of the game, as many bosses rely prominently on magic and it is quicker and more efficient to summon Zona Seeker than cast Shell on each character. In the later game it is rendered obsolete by Strago's Mighty Guard, which grants the party both Shell and Protect.
Zona Seeker teaches two important spells at fast learn rates, so party members can equip it for only a couple battles to learn them. It also teaches Shell the fastest of any esper the party can obtain for much of the game; only Alexander teaches it faster.
