Thunder Slimer

Thunder Slimer (サンダースライマー) is the sub-boss in Spark Mandrill's stage, a robot encased in a huge blob of blue slime that mainly attacks with smaller blue slime blobs that can glue X to the floor.

Under normal circumstances, Thunder Slimer can, in addition to throwing slime, shoot bolts of electricity, but if Storm Eagle had been defeated prior to the Spark Mandrill stage, that power will be lost, making the battle against it easier. Dashing and charged Buster shots can free X if he becomes glued to the floor.

After Mega Man X defeats this robot it goes berserk and starts shooting a ton of bubbles out which do not harm X.
