Marvel Knights Animation will expand its lineup of motion comics in April with an adaptation of Inhumans, the 1998-99 series by Paul Jenkins and Jae Lee.

It will be the eighth title produced by Shout! Factory since 2009, joining the likes of Spider-Woman: Agent of S.W.O.R.D., Iron Man: Extremis, Black Panther and, most recently, Astonishing X-Men: Unstoppable. The Inhumans DVD will be available beginning April 23 for $14.97.

Debuting in November 1998, the Eisner Award-winning series follows the race of genetic outsiders as Black Bolt and the rest of the Royal Family attempt to repel attacks on their island kingdom of Attilan from without and within. Inhumans ran for just 12 issues.

While a 15-year-old series -- rather than, say, something from the Avengers or Iron Man stables -- may seem an unusual choice to receive the motion-comic treatment, it's probably worth noting that Marvel Studios is gearing up for Phase Three of its cinematic universe, one that will include some of the company's more offbeat properties, like Ant-Man and Doctor Strange. An Inhumans movie was confirmed in October 2011 as part of the studio's agenda, and the third phase that begins in 2015 seems as likely a home for the project as any.

See the official synopsis for Marvel Knights Animation's Inhumans below:

The Inhumans have always been one of Marvel's most enduring oddities. A race of genetic outsiders, they live secluded in their island kingdom of Attilan, preferring not to mix with the outside world. Even stranger, their genetic mutations are self-endowed; each Inhuman, as a coming-of-age ritual, endures exposure to the Terrigen Mists, a strange substance that imparts unearthly powers--some extraordinary, some monstrous.

But now the kingdom of Attilan is under attack from without and within. Can the Royal Family, led by Black Bolt, repel the foreign invaders who blast at their outer defenses, as well as the internal threat of Black Bolt's insane brother, Maximus the Mad?

This popular series takes a classic Marvel cast of characters, and infuses it with a modern sensibility that includes international politics and an awareness of class systems. Dark and grimly compelling, the "Inhumans" is one story that won't be forgotten any time soon.
