Meet the oddest superheroes ever - Baron Sarcasm, a Scrooge-like, wealthy, cantankerous elderly man living in a castle somewhere in the French countryside; his niece, the pretty, spunky Mademoiselle Mademoiselle, also a brilliant inventor, her son Gizmo, and their cousin, a gentle giant nicknamed Captain Camembert. Together, they built a rocket in their backyard shed in 1954, went exploring into outer space, and returned today, having barely aged a day, now transformed into… The Lunatic Legion! But are they the same astronauts who left half a century ago? Discover the origins of the Legion and its first adventure in two stories by writer Jean-Marc Lofficier, French artist Cyril Bouquet and Spanish-born artist David Lafuente, known for his work on Ultimate Comics: Spider-Man and The Adventures of Archer & Armstrong.
