Tritium

Tritium is a benched member of Advance Guard, who has a power with a disastrous side effect.

Personality
Victoria describes her as quiet, reserved, and totally ill-suited for the more gung-ho attitude of her team.

Appearance
When using her power, Tritium appears as a dim silvery silhouette.

Abilities and Powers
Tritium is an Alexandria package cape. She has enough super strength to hold back a punch from a Titan or to punch through a building, she is ostensibly invincible, and she is capable of flight. However, her abilities come with the unfortunate side effect of being radioactive. The harder she fights, the more radioactivity she builds around herself, although she is immune to its effects. She labels her punches as 'Nuke punches' as a result.

Background
Tritium was not aware of the side effects of her abilities, and unfortunately killed many people around her with her radioactive nature, including her family, friends, pets and coworkers. As a result she was benched for the most part, and included in important missions.

Post-Ice Break
Tritium joined the fight against the Titans, but was unceremoniously killed by an attack from the Impaler Titan.
