Brugs are small, purple insects which appear in Metroid: Other M. Although Brugs do not have many offensive capabilities on their own, when a large group of Brugs joins together under an Emperor Brug, they can form a Brug Mass to attack.
Metroid: Other MEdit
A group of Brugs and one Emperor Brug were bred on the BOTTLE SHIP, possibly for scientific purposes. While Samus and the 07th Platoon were exploring the area, they encountered the swarm, which created a Brug Mass.
Through the use of Samus's Missiles and the Platoon's Freeze Guns, the Mass became incapacitated and the Emperor destroyed. The remaining Brugs scurried away and are not seen again through the remainder of the game.
The name 'brug' seems to come from 'bug', which is a generic name for insects like the Brugs.
- Zebesian Parasites seem similar to Brugs and may or may not represent the first depiction of the species.
- Before entering the Bottle Ship Control Room, where the boss is fought, Brugs can be seen crawling around in certain rooms. Such rooms include one with a Kick Climb shaft and the room directly outside the control room.
- After the fight, when Samus exits back through the preceding corridor, some Brugs will scurry off into the vents, the last time they are ever seen.
