For a while now the DC Animated Universe has been limited to one-off projects such as Green Lantern: First Flight and Justice League: Crisis on Two Earths, each featuring a different creative crew and voice cast. Now, for the first time since the ongoing "Dini-verse" wrapped up, one of these projects is carrying over into a direct sequel. Almost a year to the day after Superman/Batman: Public Enemies reunited Tim Daly and Kevin Conroy with their iconic roles, the two are pairing up again for Superman/Batman: Apocalypse, available on Blu-ray, DVD, and On Demand September 28th.

Like Public Enemies before it, Apocalypse adapts another story arc from the Superman/Batman comic series by Jeph Loeb, Michael Turner, and Peter Steigerwald. Ever-present DC animation stalwart Bruce Timm is yet again producing, and the script is written by Tab Murphy, who was Oscar-nominated for Gorillas in the Mist way back in 1989. If Apocalypse doesn't feature a cameo from Gorilla Grodd, that seems like a missed opportunity to me.

Apocalypse introduces Supergirl to the Batman/Superman continuity after her spaceship crashes into Gotham City Harbor. Supes is elated to have found a fellow Kryptonian (and a cousin, no less), but his excitement is soon undermined when Darkseid brainwashes Supergirl to kill Kal-El once and for all. Conroy and Daly will be joined by a solid voice cast including Andre Braugher as Darkseid, Summer Glau as Supergirl/Kara, and Ed Asner revisiting his Superman: The Animated Series role as Darkseid henchwoman Granny Goodness.

Superman/Batman: Apocalypse Two-Disc Special Edition DVD features more than 1 1/2 hours of exciting extra content, including:

• Feature film (est. 75 min)
• DC Showcase: Green Arrow (10 min)
• Sneak Peak at the Next DC Universe Animated Original Movie (10 min)
• Featurette: Supergirl: The Last Daughter of Krypton -- A comprehensive look at The Maiden of Might, from her introduction in the classic age of comics to her death in the “Crisis on Infinite Earths” crossover event to her appearance on Smallville and beyond.
• Two bonus episodes from animated television series handpicked by Bruce Timm.

Superman/Batman: Apocalypse Special Edition Blu-Ray will include more than 2 1/2 hours of intriguing bonus features, starting with all of the content available on the two-disc Special Edition DVD and adding:

• All-New Featurette: The New Gods -- This documentary covers Darkseid’s story, particularly in reference to the adaptation of Superman/Batman: Apocalypse. A primer on the wealth of material and stories contained in the New Gods series, along with a deeper understanding of why these characters -- and especially Darkseid -- are so memorable and important to the DC pantheon.
• All-New Featurette Pods
  • Orion -- The mightiest warrior on either New Genesis or Apokolips, Orion follows an almost Shakespearean arc culminating in the slaying of his father, Darkseid. This mini-featurette shines a light on this classically tragic character.
  • Mister Miracle -- This mini-featurette focuses on the greatest escape artist the universe has ever known and how he was traded in a peace effort to be raised by Darkseid, the enemy of all New Genesis.
• Two additional bonus TV series episodes handpicked by Bruce Timm.
• Digital copy on disc of the feature film.
