Dark Satellmite

Dark Satellmites are dark enemies that assist the Dark Star during the events of Mario & Luigi: Bowser's Inside Story. When fighting Mario and Luigi, they will shoot lasers at the plumbers, but can easily be dodged by jumping. Sometimes, the Dark Satellmites will jump themselves, so their attacks are dodged by not jumping. When they are defeated, they start flashing a red color. When the Dark Star attacks next, it gives a bomb to the defeated Dark Satellmite, which then jumps high in the air with it, and then lets go. Both the bomb and the Dark Satellmite fall towards the bros., who must use their hammers to hit the Satellmite back at the Dark Star, doing damage and causing its spines to retract. After two Dark Satellmite hits, the Dark Star falls to the ground for a few turns and can be damaged, making defeating the Satellmites an integral part of the battle. The bomb the Dark Satellmite drops when it falls is merely a decoy; if Mario or Luigi hammers it it will simply blow up in his face and do damage.

Dark Satellmite X
The "Dark Satellmite X" appears in the Gauntlet as an enemy assisting "Dark Star X" in Class 6. Like the Dark Star X, it has almost twice its original form's power, defense, speed, and HP. They may also heal the Dark Star X by 100 HP and give it a POW or DEF boost.
