Teen Titans: Trouble in Tokyo - Easter Eggs & Hidden Details
Easter Eggs
During a chase scene, two characters who are clear look-alikes of Kaneda and Yamagata from the iconic 1988 anime film "Akira" make a brief cameo appearance.
This is a direct homage to "Akira," one of the most influential anime films of all time. Given that the visual style of "Teen Titans" was heavily influenced by anime, this reference serves as a nod from the creators to one of their inspirations. The motorcycle chase itself is also reminiscent of sequences from "Akira."
A blob-like monster that attacks Raven bears a strong resemblance to the character No-Face from the Studio Ghibli film "Spirited Away."
This is another tribute to a classic and highly acclaimed Japanese animated film, showcasing the creators' appreciation for the works of Hayao Miyazaki and Studio Ghibli.
Beast Boy wants to visit the Wakamono Shuppan publishing company.
While not a direct crossover, this is a reference to the world of manga publishing, which is a cornerstone of Japanese pop culture. Beast Boy's desire to visit highlights his otaku-like personality. Ironically, the final battle takes place in a similar, abandoned comic book factory.
