The Tsik-Seru were organic vehicles used by the Yuuzhan Vong as atmospheric fighters.
The Tsik-Seru was a military variant of the Tsik vai and was heavily armored and equipped with Yaret-Kors. They could survive on planets with no oxygen or water. They were slower and less maneuverable than the Tsik-Vai since they were heavily armored.
Tsik-Seru participated in the Battle of Coruscant.
