Keith Ian Giffen was an American comic book illustrator and writer. He is possibly best-known for his long runs illustrating, and later writing the Legion of Super-Heroes title in the 1980s and 1990s. He also created the alien mercenary character Lobo (with Roger Slifer), and the irreverent "want-to-be" hero, Ambush Bug. Giffen is known for having an unorthodox writing style, often using characters in ways not seen before. His dialogue is usually characterized by a biting wit that is seen as much less zany than dialogue provided by longtime collaborators DeMatteis and Robert Loren Fleming. That approach has brought him both criticism and admiration, as perhaps best illustrated by the mixed (although commercially successful) response to his work in DC Comics' Justice League International (1987-1992). He also plotted and was breakdown artist for an Aquaman limited series and one-shot special in 1989 with writer Robert Loren Fleming and artist Curt Swan for DC Comics. Giffen's first published work was "The Sword and The Star", a black-and-white series featured in Marvel Preview, with writer Bill Mantlo. He has worked on titles (owned by several different companies) including Woodgod, All Star Comics, Doctor Fate, Drax the Destroyer, Heckler, Nick Fury's Howling Commandos, Reign of the Zodiac, Suicide Squad, Trencher (to be re-released in a collected edition by Boom! Studios)., T.H.U.N.D.E.R. Agents, and Vext. He was also responsible for the English adaptation of the Battle Royale and Ikki Tousen manga, as well as creating "I Luv Halloween" for Tokyopop. He also worked for Dark Horse from 1994-95 on their Comics Greatest World/Dark Horse Heroes line, as the writer of two short lived series, Division 13 and co-author, with Lovern Kindzierski, of Agents of Law. For Valiant Comics, Giffen wrote XO-Manowar, Magnus, Robot Fighter, Punx and the final issue of Solar, Man of the Atom. He took a break from the comic industry for several years, working on storyboards for television and film, including shows such as The Real Ghostbusters and Ed, Edd 'n' Eddy. He is also the lead writer for Marvel Comics' Annihilation event, having written the one-shot prologue, the lead-in stories in Thanos and Drax, the Silver Surfer as well as the main six issues mini-series. He also wrote the Star-Lord mini-series for the follow-up story Annihilation: Conquest. He currently writes Doom Patrol for DC, and is also completing an abandoned Grant Morrison plot in The Authority: the Lost Year for Wildstorm.

Kurt Busiek is an American comic book writer notable for his work on the Marvels limited series, his own title Astro City, and his four-year run on Avengers. Busiek did not read comics as a youngster, as his parents disapproved of them. He began to read them regularly around the age of 14, when he picked up a copy of Daredevil #120. This was the first part of a continuity-heavy four-part story arc; Busiek was drawn to the copious history and cross-connections with other series. Throughout high school and college, he and future writer Scott McCloud practiced making comics. During this time, Busiek also had many letters published in comic book letter columns, and originated the theory that the Phoenix was a separate being who had impersonated Jean Grey, and that therefore Grey had not died—a premise which made its way from freelancer to freelancer, and which was eventually used in the comics. During the last semester of his senior year, Busiek submitted some sample scripts to editor Dick Giordano at DC Comics. None of them sold, but they did get him invitations to pitch other material to DC editors, which led to his first professional work, a back-up story in Green Lantern #162 (Mar. 1983). Busiek has worked on a number of different titles in his career, including Arrowsmith, The Avengers, Icon, Iron Man, The Liberty Project, Ninjak, The Power Company, Red Tornado, Shockrockets, Superman: Secret Identity, Thunderbolts, Untold Tales of Spider-Man, JLA, and the award-winning Marvels and the Homage Comics title Kurt Busiek's Astro City. In 1997, Busiek began a stint as writer of Avengers alongside artist George Pérez. Pérez departed from the series in 2000, but Busiek continued as writer for two more years, collaborating with artists Alan Davis, Kieron Dwyer and others. Busiek's tenure culminated with the "Kang Dynasty" storyline. In 2003, Busiek re-teamed with Perez to create the JLA/Avengers limited series. In 2003, Busiek began a new Conan series for Dark Horse Comics, which he wrote for four years. In December 2005 Busiek signed a two-year exclusive contract with DC Comics. During DC's Infinite Crisis event, he teamed with Geoff Johns on a "One Year Later" eight-part story arc (called Up, Up and Away) that encompassed both Superman titles. In addition, he began writing the DC title Aquaman: Sword of Atlantis from issues 40-49. Busiek was the writer of Superman for two years, before followed by James Robinson starting from Superman #677. Busiek wrote a 52-issue weekly DC miniseries called Trinity, starring Batman, Superman and Wonder Woman. Each issue (except for issue #1) featured a 12-page main story by Busiek, with art by Mark Bagley, and a ten-page backup story co-written by Busiek and Fabian Nicieza, with art from various artists, including Tom Derenick, Mike Norton and Scott McDaniel. Busiek's work has won him numerous awards in the comics industry, including the Harvey Award for Best Writer in 1998 and the Eisner Award for Best Writer in 1999. In 1994, with Marvels, he won Best Finite Series/Limited Series Eisner Award and the Best Continuing or Limited Series Harvey Award; as well as the Harvey Award for Best Single Issue or Story (for Marvels #4) in 1995. In 1996, with Astro City, Busiek won both the Eisner and Harvey awards for Best New Series. He won the Best Single Issue/Single Story Eisner three years in a row from 1996–1998, as well as in 2004. Busiek won the Best Continuing Series Eisner Award in 1997–1998, as well as the Best Serialized Story award in 1998. In addition, Astro City was awarded the 1996 Best Single Issue or Story Harvey Award, and the 1998 Harvey Award for Best Continuing or Limited Series. Busiek was given the 1998 and 1999 Comics Buyer's Guide Awards for Favorite Writer, with additional nominations in 1997 and every year from 2000 to 2004. He has also received numerous Squiddy Awards, having been selected as favorite writer four years in a row from 1995 to 1998,
