Assimilator Mech

The Assimilator is a recurring entity that appears in Boss Battalion, its first official appearance being the Omega Fortress when it was in Alpha.

Appearance
The Assimilator usually takes on the form of a massive bipedal robot with a single green eye in the shape of an arrowhead.

Omega Fortress
In the Omega Fortress Alpha fight, the Assimilator can be seen with its knees inverted in a stabilizing position made to offset recoil.

Here, it wields a pair of railguns similar to those found on the NMS Shalan.

Sword
By beating Lucy during the Mother's Day Weekend event, you will recieve the Assimilator mech in the form of a sword resembling the Team Fortress 2 Eyelander.
