天然!絶滅ヒーロー!! [Tennen! Zetsumetsu Hero!!]

A delightfully absurd three-issue comedy from Shinshokan that ran in 2003, 天然!絶滅ヒーロー!! offers a playful, self-aware take on the superhero genre. The series is best known for the distinctive, energetic art and humorous storytelling of its creator, though the premise itself—a hero who is, as the title suggests, both "natural" and "endangered"—provides the core of its charm. A short but memorable burst of manga madness from the early 2000s.
