a trapeze, a reference to the death of Grayson's acrobat parents being the catalyst for him becoming Robin. Further connections to the Batman mythos include two references in the episode "The Apprentice, Pt. II", when Robin responds to a suggestion by the villain Slade that he "might be like a father to [him]" with "I already have a father" (which transitions to a shot of flying bats) and a fight scene on the rooftop of a building labeled Wayne Enterprises. The Teen Titans Go! episode "Permanent Record" would satirize the mystery of Robin's identity by explicitly giving his name as "Robin v.3: Tim Drake" (the third Robin), with "Dick Grayson" and "Jason Todd" (the second Robin) being written over. Subsequent episodes, however, establish him as Dick Grayson through vague flashbacks to his boyhood at Haley Circus. In the comics, Starfire and Raven are the real names of their respective characters. While the show does not specify this with the latter, the former acknowledges "Starfire" as the English translation of her name in the season 5 episode "Go!" and her native name, Koriand'r, is used in the season 3 episode "Betrothed". The comic versions of these characters, however, also use the civilian aliases Kory Anders and Rachel Roth, which are not used on the show. The policy of not mentioning the characters' secret identities would be broken in the season 5 premiere "Homecoming" when Elasti-Girl refers to Beast Boy by his real name, Garfield. Cyborg's real name in the comics, Victor Stone, is referenced in the season 3 premiere "Deception" when he uses "Stone" as an undercover alias, although the series does not identify this as his real name. Production Soundtrack The series is known for featuring both an English and Japanese version of its title theme song, created by Andy Sturmer and performed by the Japanese band Puffy AmiYumi. The title theme used in the regions where the show was broadcast varied; some would play only one version, while Japan - and the English language video editions - would use both, according to the respective episode's plot theme: The English lyrics for more serious stories, the Japanese version for more comedic tones. The first-season episode "Mad Mod" also featured another song by Puffy AmiYumi, "K2G". In the feature-length film Trouble in Tokyo, a literal translation of the Japanese song, whose actual lyrics differ greatly from its English counterpart, is performed
