A firm believer in experimentation and constant learning of new techniques, Miguel’s first professional work for Marvel was the 8-issue miniseries Marvel Illustrated: The Iliad, written by Roy Thomas. That was followed by The Trojan War, also written by Thomas.
Later, Sepulveda penciled one of the Thor: God-Size Special stories, and collaborated in a couple issues of Secret Invasion: X-Men, before taking over as ongoing artist on Thunderbolts, first with Andy Diggle, and later with Jeff Parker as writers. During that time, he also did a cover for Spider-Man: The Clone Saga #2 and the short story Wolverine: Carni-Brawl. He then moved to the cosmic event The Thanos Imperative and its epilogue, the one-shot Devastation.
Miguel's first work for DC was the Superman / Batman Annual, which he followed with JLA #58, Green Lantern: War of the Green Lanterns: Aftermath, or the controversial Action Comics #900 story written by David Goyer where Superman renounces his American citizenship. After starting the New-52 Stormwatch book part of the New-52, Miguel moved to Red Lanterns with issue 10 of the book where he did a really successful run. At Dark Horse, Miguel worked on Lone Wolf 2100 or the Captain Midnight series. He's also worked for Blizzard Entertainment on their Starcraft and Hearthstone franchises.
Returning to Marvel, Miguel worked on Indestructible Hulk, the Ant-Man Movie Prelude, Captain America or most recently, Kingpin.
Miguel's most recent work has been for Blizzard, where he's worked on books like Starcraft or Hearthstone, and Starcraft: Soldiers for Dark Horse. Miguel is currently available.
