The Bat Sentinel C-Cu is a large sentinel robot designed to fend off invaders within the Batcave: Outer Caverns.
The sentinel is the second boss encountered alongside the Bat Sentinel DP-5 in the Batcave: Outer Caverns raid.
- Brother Eye and Brainiac have taken over the Batcave's mainframe and, along with it, the substantial automated defense and security forces. Both heroes and villains battle against Earth's real enemy in this 8-player raid.
Throughout the fight, they will bombard the raid with area effect damage - players should beware the moving markers on the ground and actively dodge them.
The sentinels will initially be vulnerable one at a time, each using different attacks. They will periodically trade places, the active one being vulnerable and the passive one circling the arena using AE attacks.
The blue sentinel will be up first. He is the more dangerous of the two. Those in melee should be wary of its Sonic Burst - if caught up in them it means near-certain K.O. This attack is telegraphed with a warning and the Lethal Attack marker (similarly to Mr. Freeze in Arkham) and has a relatively short range.
The red one (Sentinel C-CU) doesn't have any outstanding attacks, but the AE damage will be more concentrated - players should avoid the marked areas on the ground.
When one of the sentinels is brough down to 20% HP, the passive one will join the fight, forcing the raid to deal with them both at the same time, but will stop the AE bombardment. Raiders should focus on bringing down the weaker one first.
