Aquaman Vol. 3: Manta vs. Machine
"Year of the Villain" strikes Aquaman as Black Manta and his Mecha Manta invade Amnesty Bay with one target in mind: Aqualad! It's land versus sea in a battle of titanic proportion! But which side will Jackson Hyde choose-his mentor or his father? Then, Aquaman encounters a new crisis when Mera unexpectedly goes into labor...and things don't look good for the queen of Atlantis.
Collects Aquaman #53-57 and Aquaman Annual #2.
