"Aquaman's Royal Ride" from Aquaman: Sword of Atlantis #46 (DC, 2006) by Kurt Busiek, Karl Kesel and Phil Winslade
Rick Veitch's Aquaman vol.6 would be responsible for giving him a hand made of water and various mystical abilities. The series changed hands several times, from Veitch to Ostander to Pfeiffer to Arcudi, but its more interesting addition, I thought, was Sub Diego. See, one of the things that made Aquaman difficult to write for is that he had no American "contextualizing city". Atlantis is this magical place with an alien culture, and scarcely the equivalent of Metropolis or Gotham. Sub Diego was a part of San Diego that fell into the sea, and whose inhabitants for some reason were given the ability to breathe water. Suddenly, Aquaman had his own American town to protect. It's an interesting notion that carried over to Sword of Atlantis, the book's new name as of its 40th issue. We're now One Year Later than the Infinite Crisis in which Aquaman presumably died. We have a new Aquaman, Arthur Joseph Curry, whose connection to the previous Aquaman was initially a mystery. Haven't read it yet, but it's on my list. Vol.6 ran under that title until issue 57 and the end of 2007.
