Captain Yvette Deladrier commands the corvette *Rodger Young*, demonstrating decisive leadership and piloting prowess when her ship narrowly evades destruction from a meteor collision. She commends her bridge team, specifically praising Carmen Ibanez and Zander Barcalow as a "hell of a flight team" for their actions during the crisis. She later leads the *Rodger Young* through the invasion of Klendathu and subsequent missions, including a rescue operation on Planet P. During the Invasion of Planet P, Bug Plasma strikes the vessel, tearing it in half. Facing imminent destruction, Captain Deladrier orders the crew to abandon ship. While attempting to escape, she is fatally crushed by emergency doors, her final words an incomplete command to Ibanez and Barcalow: "Abandon ship, that's an-...". The narrative centers solely on her command role and fate during the Planet P engagement. A counterpart character in the novel source material, also named Yvette Deladrier and captaining the *Rodger Young*, survives the Planet P assault to capture the Brain Bug, diverging significantly from the anime adaptation.
