Comics and Manga
While the God's Number of a Rubik's Cube has been determined to be 20 by computer algorithms, in DC Comics Final Crisis crossover series, it is shown that a real god can solve it in less (with the actual number being 17). The time-traveling New God Metron is depicted with a cube; and the solving of a cube utilizing a God's Number maneuver of 17 results in a flash of blinding supernatural luminosity which destroys evil minions of Darkseid in the vicinity. In the manga and anime of Tonari no Kaibutsu-kun Yoshida Haru is seen to be solving a Rubik's Cube in episode 7. However, it is not shown that he has solved the Rubik's Cube in the episode or any other episode.
