Yankee Doodle Dandy Yankee Doodle Dandy (real name John Dandy) is a DC Comics character introduced in January 1992 in Doom Patrol, Vol. 2, #51. The character was first devised for Showcase by Bob Oksner in 1964 but the art did not appear until 28 years had passed. This hero's name is based upon the song "Yankee Doodle". He is the second DC character named from the song, the first being Yankee Poodle (aka Earth-C's Rova Barkitt) who was part of the Zoo Crew encountered in New Teen Titans #16 in February 1982. John at one point steals the formula for "pseudoderm" (used in the Question's mask) from its inventor, Aristotle Rodor. Yellow Lantern Yellow Peri Yellowjacket Yo-Yo Yo-Yo is a name used by two characters in the DC Universe. Flashpoint Yo-Yo The original was a clown-like henchman of the Joker who first appeared during the Flashpoint timeline; she was created by Geoff Johns and Andy Kubert and first appeared in Flashpoint (vol. 2) #1 (2011). Chang Jie-Ru In 2011, The New 52 rebooted the DC universe. Chang Jie-Ru uses the name as a member of the Suicide Squad. He has the ability to increase and decrease his mass. When back at Belle Reve, Yo-Yo is caught up in a supervillain prison riot, tasked alongside Deadshot and El Diablo with quelling the inmate rebellion. He is ordered by Amanda Waller to retrieve King Shark from his holding cell. Yo-Yo uses his ability to slip through the bars, where an otherwise immobile King Shark devours the mass-shifter whole. King Shark lowers his head to stare blankly at Yo-Yo's blood congealing on the cell floor, perhaps feeling regret for what he has done to his fellow team member. Yo-Yo in other media The Flashpoint version of Yo-Yo appears in Justice League: The Flashpoint Paradox, voiced by Hynden Walch. Young Frankenstein Young Frankenstein is a fictional character appearing in American comic books published by DC Comics. Little is known about the origin of Young Frankenstein. At one point, Young Frankenstein was a member of the Teen Titans in-between the events of Infinite Crisis and One Year Later. A picture of him clearly shows him as a younger version of the famous Frankenstein, another DC Comics character based on the famous monster and a member of the Seven Soldiers of Victory. What the connection is between the two has yet to be explained. He
