"Suicide Squad" The Black Vault

Amanda Waller sends the Suicide Squad to retrieve a mysterious cosmic item held in a heavily guarded prison beneath the Laptev Sea. The object turns out to be a portal to the Phantom Zone, and inside it the team finds a deranged General Zod, who has been trapped there long enough to lose his grip on sanity. Freeing the metahuman hacker known as Hack along the way, the Squad has to fight through the portal's guardians, the Annihilation Brigade, to get the item back to Belle Reve.
