The highest-profile comiXology holdout is no longer holding out. As teased late last week, releases from Dark Horse Comics are now available via the leading digital comics distributor -- specifically, the publisher's "full digital catalog of collections, graphic novels and manga," as specified in comiXology's announcement. Single issues of Dark Horse titles will remain available only on Dark Horse's proprietary platform, Dark Horse Digital.

Series now available on comiXology include some of the most notable titles in Dark Horse's 29-year history, including "Hellboy," "Sin City," "Buffy the Vampire Slayer," "300," "Fear Agent," "Usagi Yojimbo" and "Lone Wolf and Cub." In the press release, Dark Horse Comics President and Publisher Mike Richardson said that it was a matter of bringing the titles already on Amazon's Kindle Store over to its corporate sibling, comiXology.

"We are very excited to announce that we have reached an agreement which brings the Dark Horse catalog found in the Kindle Store to the comiXology platform," Richardson said in a statement. "For the first time, hundreds of Dark Horse graphic novels will be available to comiXology's devoted readers. The technology is stellar and we are pleased that our books will be showcased flawlessly."

comiXology first teased Dark Horse coming to its platform last Friday, with a short video featuring Hellboy and a countdown clock.
