The trailer starts in a misty landscape filled with industrial machinery and cogs turning. Workers from various game universes like Donkey Kong, Mario, and Animal Crossing are shown laboring. The iconic Super Smash Bros. logo flashes, and then two shadows appear on a wall—each adorned with a pair of cat ears.

Suddenly, a manifesto flies into frame, landing on a workbench. The workers look puzzled, but then the camera reveals the authors: Marx and Engels, reimagined as adorable trans catgirls with revolutionary attire, berets, cat ears, and tails. They flick their tails in unison as the screen splashes, “Marx & Engels Ignite the Struggle!”

Marx is dressed in a red skirt and black jacket, accessorized with a red beret and a hammer & sickle brooch. Engels wears a blue skirt and white jacket, a blue beret, and also sports a similar brooch. Both have expressive cat ears and tails.
