Superman/Batman: Apocalypse

After a spaceship splashes down in Gotham City Harbor, Batman and Superman encounter a mysterious Kryptonian with powers as great as those of the Man of Steel. The Kryptonian is soon revealed to be Kara, cousin of Superman, who takes her under his wing to educate her about the ways of Earth. However, the villainous Darkseid has other plans. Seeing an opportunity to finally defeat Superman, Darkseid abducts and gains control of Kara, utilizing the powerful Kryptonian to do his bidding. It’s up to Batman and Superman to save Kara, but they’ll have to take the fight to Darkseid within his hostile world – where unknown, deadly threats lurk around every corner, including a brainwashed Kryptonian able to match Superman blow-for-blow.
