Executive Meddling: Starhawk was supposed to be turned evil and killed off, but the editors wouldn't let Valentino. His departure allowed Michael Gallagher (who did like the character) to keep him around and redeem him.
Fan Nickname: DnA for the creative team behind the 2008 series, Dan Abnett and Andy Lanning.
Gotgino(Guardians of the Galaxy In Name Only) for Bendis run on the series.
What Could Have Been: Jim Valentino has an entire thread here for this Trope. Essentially: Starhawk and Vance Astro would both die, the team would fight Kang and several of their groups of enemies (who would be redesigned to turn them into even more blatant Legion of Super-Heroes analogues), the Protege would turn out to be the Beyonder, and by the end of Valentino's planned run, the group would morph into a Legion of Super-Heroes type organization with a roster of over several dozen heroes.
Ascended Fanon: Vin Diesel's casting as Groot resulted from a fan-made rumor.
Colbert Bump: After appearing in the trailer, "Hooked on a Feeling" by Blue Swede sold more than 2000 downloads within 24 hours of the trailer being released - a 700% increase in sales.
