Lark

 is a member of the hero team Auzure.

Appearance
Lark's costume is composed of a metallic silver suit over a black dress shirt. He wears a full-face mask resembling a bird's beak, consisting of two panels sweeping across the sides of his face.

Early-Ward
Lark conducted an interview with Victoria Dallon when she was applying to hero teams. He appeared to have an ulterior motive of using her to recruit Amy, causing Victoria to leave the interview.

Post-Fallen fall
Following the portal sabotage, Lark was present at the hero gathering, alongside his teammates Dido and Spell.

When Breakthrough established their hero network, Lark agreed to bring Auzure on board, but stressed the importance of money to his team.

Post-Goddess' Takeover
With Dido, he attended the hero meeting to discuss what had happened to the Navigators. He brought up Amy as a potential culprit, a possibility which was promptly shot down.

Trivia

 * The word 'lark' refers either to a type of small songbird, or to something done for amusement. Given his bird-like mask, Lark's name likely refers to the former.
