In a fusion of animated styles, a character resembling Samurai Jack stands in a doorway with a group of characters from Steven Universe, including a small boy, a tall figure in a white robe, a woman in a black and red outfit, and a purple gem character, before the scene cuts to a close-up of the samurai character shouting while holding a sword, followed by a violent clash where the samurai is struck by a pink energy blast, causing the purple gem character to be thrown backward and splattered with pink blood, and finally, the exterior of a house with a bloodstain on the window.
