Manglers are aquatic creatures from the Gears of War universe. Residing in submerged areas of the Hollows, these creatures were often used by the Locust to pull their patrol boats in the lakes and rivers surrounding Nexus. Manglers swam in large shoals, and were very aggressive. Before the Sinking of Jacinto, Manglers were only present in the Hollows. However, the sinking released large numbers of the creatures into the Serano Ocean, along with Leviathans.
