Ulk

Ulk is a Xenig, a type of mech. He and his chassis are one, similar to a mind being an integral part of a body. However, the personality can switch to a new chassis "body" if one is available. Ulk's current chassis looks like a pencil with an oversized eraser. Ulk's desire for a gross of yellow rubber ducks prompts him to hang around and watch the action between Cube #347, Second Federation, and Hive. He eventually gets his rubber ducks ("Let Sleeping Borg Lie, Part I-III" [BRG]).
