Viking Time-Traveling Hero in a Neon Comic Time Machine

Epic Viking warrior in bold comic-book style with thick black inks, bright cel shading, and halftone textures. He stands inside and exploding out of a steampunk time machine: brass riveted chassis, gears, copper piping, glowing runes, and spinning crystal dials. A swirling blue and magenta timestream portal erupts behind him with jagged energy lines and scattered stars. The Viking wears a fur cloak, leather tunic, metal gauntlets, a horned-like helmet, and a long braided beard; he wields a gleaming battle-ax, shield strapped to his back. The scene blends eras: icy fjord foreground, neon-metropolis skyline in the distance, and inset panels showing timer dials and countdown. A bold onomatopoeia like WHOOSH in a jagged speech bubble. Dynamic low-angle perspective, motion lines, high-contrast colors: electric blues, golds, reds, and icy whites. Vibe: a crossover of classic superhero art and Norse myth with time travel.
