Eighteight wears dark purple colored armor, which has a hoop feature at the end of her helmet. Compared to her two brothers, Eighteight is smaller in stature and mainly wields laser guns, instead of weaponry attached to her suit. Notably, her x-shaped eye holes are pink, the same as Sixsix's eye holes in Omniverse.
Little is known about Eighteight's personality, except that she does not like being told that she resembles her two brothers.
According to Thunderpig, Eighteight tends to make witty remarks.
Powers and Abilities
A Sotoraggian bounty hunter, Eighteight is equipped with a large arsenal. This includes twin laser guns, a power sword, a jetpack. and appears to have similar nanotech enhancements akin to her younger brother Sevenseven; able to morph her hand into an energy buzz saw.
Physically, she is strong enough to resist Gravattack's gravity manipulation (albeit with some difficulty). In addition, she is highly agile and skilled in hand-to-hand combat, being able to fight on par with Rook.
In Vilgax Must Croak, Eighteight was hired by the Incurseans, along with Sixsix and Sevenseven, to kill Vilgax. Ultimately, the three of them and Attea were defeated by Vilgax when they were finally able to confront him directly. However, they were able to escape before the Plumbers arrived.
In Cough It Up, she, along with her siblings, was hired by Psyphon to get him a precious item that had been stolen from him. They found Argit, who possessed the item, and fought for it with Ben, Rook and Spanner. She clashed with Rook, later fleeing when Sevenseven managed to capture Argit. At the Black Hole, she suggested using her energy buzz saw on Argit after learning the latter had swallowed the item. At the end of the episode, she was banned from Undertown.
