tries to stop MegaGon before the train crashes, but Daishi possesses the oil-filled cars himself and crashes them into MegaGon, sending him into a mindless rage. As Jiro faces him with Equus, he starts questioning the true nature of the beasts.

A quartet of comedic rock stars called "Mountain Horse" suddenly gain superhuman powers after listening to a rock concert they opened for. The powers themselves are not very strong, but enough that they get noticed by Fuurouta of the Superhuman Bureau, and an agent named Fugimoto. After overhearing Fugimoto's plan to sell chocolate with a secret anti-superhuman chemical inside, the group decides to infiltrate the warehouse and destroy the chocolate before it gets distributed, though they have to fight against a giant security robot and even a rivalsuperhuman rock band. After one of them gets killed in the fight, the band successfully destroys the chocolate, and keeps one sample as insurance against Fugimoto. Despite Fuurouta and Jiro's offer the remaining band members decide not to join the Superhuman Bureau, and instead continue going on stage as a comedy group.
