In 1993, Marvel's House of Ideas created 27 new characters for each of their Annuals that year. In an interview, Mark Gruenwald specifically described how these fresh, new characters were meant to thrive in the Marvel Universe, unlike poor Squirrel Girl who was created three years prior and never heard from again.
Oh how the turns have tabled...Squirrel Girl recently finished a 58 issue ongoing series (with companion graphic novel) and -- outside the mild lasting success of Genis-Vell and Adam X -- the remaining 25 characters have hardly made 58 appearances COMBINED since 1993. Just goes to show how fickle and unpredictable success can be in comic books. Squirrel Girl spent time with the new Avengers of A.I.M. and as nanny to the daughter of Luke Cage and Jessica Jones. Her plucky optimism disguises a shrewd mind that has served her in beating major villains from Doctor Doom to Thanos. Today we celebrate the unlikely staying power of Doreen Green, the Unbeatable Squirrel Girl!
