Occasional science/fantasy violence throughout. It is usually presented in a highly stylized fashion and rarely results in any human injury. Many robots are blown up during these sequences. The most graphic incident involves a brief battle between a superpowered girl and a flying manta ray. She kills the manta ray by stabbing it in the head with her sword and black blood fountains out from the wound.
The only onscreen human casualty involves a man somewhat accidentally falling into a pool of lava (not graphic).
