"Silence"

Silence was a gift from Roodaka prior to the war with the Brotherhood of Makuta. What he was before and where she found him, no one knows, but it is certain that her Rhotuka is responsible for his appearance.

Silence was a highly skilled and talented operative who specialized in the quick, clean (and, above all, quiet) abduction of Toa, Turaga, Matoran, Brotherhood of Makuta members, or anyone else who could possibly pose a threat to the Dark Hunters. He moved like a shadow, slipping into even the most heavily guarded fortresses and vigilantly protected islands and emerging with his victims just as easily. Even when he was on Odina, no one knew just where he was for sure...

Powers and Abilities
Silence had the natural ability to create a field around himself that completely deadened all sound, allowing him to move silently. The field extended just less than a Bio around his body, an exact field radius of three feet, allowing him to grab and subdue targets without their screams being heard. He had a double-edged blade mounted on his forearms and carried a Kanoka Launcher equipped with freeze disks. His armor was also surprisingly heavy for one who favors stealth.
