Though the annals of history are unclear, a Seeker who became ruler of Easter Island may have used this Titan to defend against the island's enemies. The maoi statues on the island may have, in turn, been built to honor Sentinel.
LeBlanche invoked Sentinel to protect Sophie from a trap in the Crystal Caves where it worked beside Albion to stop the trap from reaching Sophie. After she reached the trapped throne, both Titans were called back to their Amulets by LeBlanche.
Sentinel was again used by LeBlanche to defend the Casterwills during the battle of the Fortress of Iron Will. After fending off numerous attacks from Silent Soldiers, it was defeated by Marduk and his Cerberus.
Sentinel's Stoneshield ability can create energy walls or spheres of various sizes. The form of this energy is dependent on who is being guarded and the situation in which this Titan is defending.
- His summoning command is 'Perfect defense.'
- Sentinel's design is based upon the famous moai statues of Easter Island.
