Mobile Suit Gundam: The Witch from Mercury features a female protagonist in a role typically reserved for males in the Gundam franchise, with heavy emphasis on identity elements and relationships. Some viewers may feel narrative decisions prioritize modern representation over classic story development and character growth, occasionally sacrificing dramatic tension for ideological themes.

Traditional gender norms and familial structures are subverted, with major focus on unconventional relationships and a skeptical view of established authority and parental roles. Masculinity is often downplayed, and the series appears eager to signal progressive credentials over celebrating more classic values of perseverance or heroism.

Alternative viewpoints are largely absent or given little depth, and those holding to traditional beliefs are often presented as antagonists or outmoded obstacles. The show's central themes align closely with present-day ideological narratives, with little internal debate, delivering a fairly one-sided worldview throughout.
