Eduardo is a student at Public School 20 Anna Silver who was popular because he claimed to have seen pop star Taylor Swift on Yancy Street. He's in the same science class, same physical education class, and same art class as both Lunella and Zoe, and was present when Coach Hrbek accidentally activated the Omni-Wave Projector allowing the Killer-Folk and Devil Dinosaur to cross over from Earth-78411.
When the school caught on fire due to Sasha, Lily, and another girl playing with matches, after initially being frightened by Devil Dinosaur, it was Eduardo who realized that Moon Girl was allowing Ms. Dominguez's science class to use the Mutant Devil-Beast as a slide to escape the blaze. He then witnessed the subsequent battle between Hulk and Devil Dinosaur, which destroyed several responding FDNY firetrucks, as well as part of the school.
