The sentinels are round shaped Mechas. They use a kind of green light to locate the intruder.
In Rayman Legends, sentinels appear as hostile mechas. Their viewfinder emits green light, until an intruder comes into contact with it, the light will turn red and Mecha send a deadly laser to its target. They appear in both subsea installations at water depths. Some sentinels are mobile, which makes them more difficult to avoid them. Others are in poor condition, they emit flashes of light, but it can be reactivated at any time.
- The viewfinder of the sentinels reminds approximately that of the Grolgoth.
