An all-terrain dino tank.

— Description, Sonic the Hedgehog Encyclo-speed-ia

The Triceratank[1] (トリケラタンク[2] Torikeratanku?) is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, triceratops-based Badnik model serving Dr. Eggman and Eggman Nega.


Like their name implies, the Triceratanks resemble a cross between a triceratops and a tank, with the head and body of a triceratops and black and gray treads with blue wheel caps in place of legs. They are also short and pink with pink eyes.


In Sonic Rush Adventure, the Triceratanks appear as enemies. They are encountered in Plant Kingdom, Hidden Island 6, and Hidden Island 7.

In gameplay, the Triceratanks trundle back and forth on the ground within the spot they are stationed at. When they notice the playable character however, they will try charging into them in order to cause damage with their impact. However, the Triceratanks are easily destroyed with any attack.

Powers and abilities

The Triceratanks possess sharp horns that they can use to skewer their enemies.
