Batman teamed with Nightwing and Oracle to pursue the case, while other super intelligent gorillas that questioned Grimm's loyalties tailed him, and local mob boss Roland Desmond hired Lady Vic to help him pursue other intentions toward Grimm-- likely involving his massive simian heart. The matter resolved with Grimm's cargo ship sunk and ther gorilla in Blockbuster's clutches, in a story by Chuck Dixon, Graham Nolan, & Mark Pennington.
Batman continued, "Meanwhile, Atlantis is attacked by the gorilla sub The Kong under Admiral Trafalgo-- in an attempt to steal a mystic crystal called The Eye of Poseidon to power their morphic resonance array." The Martian Manhunter had determined this through a mental scan, and sent "Aqua-Ape" to rout the gorilla forces. Several of the Sea-Monkey King's confidants, like Tempest and Vulko, where transformed into gorillas loyal to Trafalgo, forcing The Prime Ape of the Seven Seas into combat. Unaffected heroines Mera and Dolphin helped steer Tempest and occasionally Aquaman back toward the side of humanity. Eventually, Aquaman overloaded the Eye of Poseidon, not only restoring the Atlanteans' humanity, but even causing members of the ape forces to go human. The Kong retreated, but Aquaman pursued, in a story by John Ostrander, Mark Bright, & Dick Giordano. Batman quotes written by Len Kaminski.
