Big Boy #20

In "La Cité des trois cauchemars," a Nazi submarine awakens in the present, having journeyed through time to three different eras—each a nightmare of its own making. As the crew confronts the echoes of their past, they face a choice that could redefine their fate, but not before the weight of history catches up to them.

In "Canon infernal," a mysterious moon-dweller convinces a group of men to build a massive cannon, claiming it’s necessary to return him to the moon. As the machine takes shape, the truth unravels: the being is not from the sky, but a mole-man whose real aim is to be launched deep into the Earth. When the cannon fires, the men seal the hole behind him, cutting off his only way back.
