The Mesets resembles a human-sized crow in appearance and has the ability to fly and chase after their prey. Its behavior is similar to a common crow however, it possesses a greater intelligence than most mutations, choosing to attack its victims when they are distracted by other dangers. Its main venue of attack is to grab its victim and after reaching a certain height, drop them, which causes moderate damage. A Mesets will also try to rake opponents with its razor sharp talons. Mesets are a very rare mutation, only emerging from specific chrysalids during Jake and Sherry's search for the data files in the Edonian mountains, although Neo-Umbrella J'avo occasionally transform into them. The Mesets' head, strangely, is not avian-shaped at all, and is positioned upside down.
