Yankee Doodle Dandy (comics)
Appearance
Yankee Doodle Dandy (real name John Dandy) is a DC Comics character introduced in January 1992 in Doom Patrol, Vol. 2, #51.
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.
