Agira is a ceratopsian dinosaur-like Kaiju from episodes 32 and 46 of Ultraseven as one of the titular Ultra's Capsule Kaiju.

Agira made his debut appearance fighting against the monster Rigger, as Dan could not transform at the time and the UG could not damage him. Agira managed to do well against the monster for the first half of the battle, but Rigger's tail proved to be too much for Agira to handle. As a result, Dan called Agira back before anymore harm could be done and went on to defeat Rigger himself as Ultraseven.

Agira was used again against the Alien Salome's weapon, the Imitation Ultraseven. However, there was nothing much that Agira could do against the copy of his master. Agira was easily beaten down by Imitation Ultraseven, who beat him down and hurled the monster into a valley where he eventually returned to his capsule, defeated. Since then, Agira would be greatly remembered by Ultraseven as a heroic monster.
