Barite Lastar

Barite Lastar (パーティラスター) is the wall-walking enemy in Mega Man X2 and Mega Man Xtreme that shoots 3-way lasers. It appears in Flame Stag's, Bubble Crab's, and a few of the X-Hunters stages.

Once Mega Man X is spotted, it will walk around to find a proper position, spin its front cannon then shoot a 3-way laser shot.

It is susceptible to all weapons except for the Crystal Hunter, and the X-Buster itself is able to destroy them easily. However, due to their common positioning within narrow walls, the Silk Shot is also good weapon choice against them.
