"Gatherer"

"Gatherer" was a former Matoran leader who became a Dark Hunter.

History
"Gatherer" once lived on an unknown island as a Matoran leader. Interfering with a Dark Hunter mission, he was detained and brought to Odina. There, "The Shadowed One" forcibly inducted him into the Dark Hunters.

One of his latest missions was to find out about a "mysterious third player" whose power was said to rival both the Dark Hunters and the Brotherhood of Makuta.

After Teridax's death he evacuated the Matoran Universe to Spherus Magna.

Personality
"Gatherer" was once a fair and brave as a Matoran leader, but these virtues were stripped from him after his conscription into the Dark Hunters.

Powers & Tools
With every opponent he defeated, the "Gatherer" took a piece of the foe's armor and added it to his own. He had no need for food or sleep, and could psychically command subterranean Rahi to do his bidding. He also had a wide array of weapons, including blades, an energy cannon, a Kanoka Disk Launcher, and "mind scramble" Rhotuka Spinners.
