suffering dissociative identity disorder (DID). In 1998, David killed off Banner's long-time love Betty Ross. Marvel executives used Ross' death as an opportunity to pursue the return of the Savage Hulk. David disagreed, leading to his parting ways with Marvel. Also in 1998, Marvel relaunched The Rampaging Hulk as a standard comic book rather than as a comics magazine. The Incredible Hulk was again cancelled with issue #474 of its second volume in March 1999 and was replaced with a new series, Hulk the following month, with returning writer Byrne and art by Ron Garney. New series writer Paul Jenkins developed the Hulk's multiple dissociative identities, and his run was followed by Bruce Jones with his run featuring Banner being pursued by a secret conspiracy and aided by the mysterious Mr. Blue. Jones appended his 43-issue Incredible Hulk run with the limited series Hulk/Thing: Hard Knocks #1–4 (Nov. 2004 – Feb. 2005), which Marvel published after putting the ongoing series on hiatus. Peter David, who had initially signed a contract for the six-issue Tempest Fugit limited series, returned as writer when it was decided to make that story the first five parts of the revived (vol. 3). After a four-part tie-in to the "House of M" storyline and a one-issue epilogue, David left the series once more, citing the need to do non-Hulk work for the sake of his career. Writer Greg Pak took over the series in 2006, leading the Hulk through several crossover storylines including "Planet Hulk" and "World War Hulk", which left the Hulk temporarily incapacitated and replaced as the series' title character by the demigod Hercules in the retitled The Incredible Hercules (Feb. 2008). The Hulk returned periodically in Hulk, which then starred the new Red Hulk. In September 2009, The Incredible Hulk was relaunched as The Incredible Hulk (vol. 2) #600. The series was retitled The Incredible Hulks with issue #612 (Nov. 2010) to encompass the Hulk's expanded family, and ran until issue #635 (Oct. 2011) when it was replaced with The Incredible Hulk (vol. 3) (15 issues, Dec. 2011 – Dec. 2012) written by Jason Aaron with art by Marc Silvestri. As part of Marvel's 2012 Marvel NOW! relaunch, a series called The Indestructible Hulk (Nov. 2012) debuted under the creative team of Mark Waid and Leinil Yu. This series was replaced in 2014 with The Hulk by Waid and artist Mark Bagley. A
