The Gelatitan is a mark in Final Fantasy XIII. It is the first of six marks that must be defeated within Taejin's Tower to ascend to the top. The Menhirrim that gives out the mission (Mission 21) is located on the tower's Second Tier. A group of Gelatitans are later fought in Mission 60, as part of the Cie'th Stone circle grouping that, once every mission in the circle has been completed, will unleash Shaolong Gui and Long Gui on the Archylte Steppe.
