Mgalekgolo (Earth-2042)

"They're all scary and angry and they like to smash things."

- Unidentified clone trooper

The Mgalekgolo is a gestalt of Lekgolo, which are a small sentient worm-like species that group together to exponentially increase their intelligence, strength, and maneuverability. Of the myriad Lekgolo collectives, the best known is the Mgalekgolo, a bipedal form that is used for heavy assault. Ironically, the Mgalekgolo is among the least common Lekgolo configurations, but due to their formidable combat capabilities they were the most commonly fielded by the Covenant and later the Confederacy of Independent Systems during the Clone Wars.
