Brake is a holographic entity leading the alien group Dark Spinner, his consciousness transferred into the computer system of the Giant UFO Mother Ship "Ō" after losing his original physical form during a catastrophic pole shift on his home planet, Dark. Existing as a distinctive purple hologram, this condition fuels his intense desire to return home, driving his actions.

He radiates significant pride and a notably short temper, demanding success from subordinates and reacting harshly to their failures. In stark contrast, he shows unconditional affection towards his daughter, Chamber, readily forgiving her mistakes and expressing deep sympathy for her struggles. This highlights his character: merciless towards underlings like Clutch and Oiler, yet deeply protective and loving towards family.

Strategically, Brake directs Dark Spinner to harvest Earth Energy, essential for conversion into Dark Energy to sustain his species. After repeated failures, he initiates a high-risk plan, landing the Mother Ship directly on Earth at Garand Canyon. This location houses ancient ruins with systems capable of mass energy absorption, justifying the danger. During the operation, he personally confronts Earth Granner forces, specifically Granner R and Granner K, leveraging the Mother Ship's combat systems. Despite formidable power, he is defeated, resulting in the loss of nearly all accumulated Earth Energy.

A trace amount of preserved energy prevents the Mother Ship's destruction. This minor success prompts him and his group to celebrate with a Christmas feast, a moment of respite. His leadership continues to focus on reclaiming Earth Energy, underscoring his unwavering commitment to restoring Dark.
