Tentolancer

Tentolancer is the sub-boss of the mid-stage (the airship) of Mega Man Zero 2.

Its shaped as a large ladybug robot and its one of the primary weapons of Neo Arcadia, evidenced by the fact that they are mass produced (Fefnir's stage) and they are used for large air strikes (mid-stage).

Weaponry
They are equiped with plasma guns (bullets) and they also have the capability of using missiles, and several explosive charges.

At some point, they can be remote controlled or are capable of creating own objectives, since one of them attacks Zero indiviually.

They are also capable of transporting troops, although this seems irregular, due to the fact that they travel at fast speeds and have flat tops.
