The Monoeyes (モノアイ Monoai) are the second mission mid-bosses in Metal Slug 3.

Information

The Monoeyes are a 15-meter tall, humanoid aliens and the enigmatic guardians of the Monoeye UFO. They're named for the large eye that seems to be their sole facial feature. They attack at anyone who dares to get too close to the UFO.

Like most members of the Martian forces, Monoeye abilities appear to be mental in nature. In the Monoeyes' case, they appear to posses teleportation, telekinesis, pyrokinesis, and psychological communication.

Monoeyes possess vast knowledge, and offer it to those who they deem worthy.

Boss Synopsis

Found at the end of Mission 2, the searchlights on the site will burst, and then six Monoeyes materialize around the meteorite. They will then levitate around it while firing light sphere aimed at the player, in fixed intervals, depending on the speed that they are rotating.

The Monoeyes are weak to the zombie player's Vomit Laser. With good positioning, this will finish them off in two lasers.

Once all Monoeyes retreat, the Monoeye UFO bursts out from the meteorite and starts to attack.

Variants

Trivia
