The Geiseric is an enemy from Final Fantasy XIII-2. It is found in Academia -400 AF-, blocking a pathway towards the northwest. To find it, the player must head to the New Town area and head east. It is near three blocked pathways represented by red Obstacle symbols on the map. Once it has been defeated, the player must close the gate in the Historia Crux and return if they wish to fight it again.
Geiseric is a different spelling of Genseric. Genseric was the 5th century king of Vandals and Alans that played a key role in the ultimate demise of the Western Roman Empire.
