Aqualad was a fantastic sidekick, working as a partner alongside Aquaman, but the concept didn't really hold up to the test of time. The character was often treated as a punchline for many years, even as Peter David was doing his seminal work with Aquaman.
To understand just how huge Phil Jimenez's work on Tempest was, it's important to understand the relationship behind it. Neal Pozner was a longtime creator and editor at DC, and had created Aquaman's blue camouflage costume. Phil describes Neal as his first mentor in comics, but they also became a couple. Neal was HIV positive, and Phil cared for him until his death. So when Phil Jimenez took this long standing joke of a character and revolutionized him, creating a new look that honored a design his partner had created, and then came out in the editorial page of the last issue and dedicated the series to him, it was an act of profound passion both for his partner and for the character.
It's thanks to the incredible work of Phil Jimenez that Garth became Tempest, a very powerful character deserving to be the high counselor of Atlantis and the best friend of the King.
We've done very little to his story other than to elaborate on his childhood, making the Idyllis a penal colony within Xebel where Orm has placed all magic weilders of Atlantis to shore up his own power. Rather than making Garth an outcast for his purple eyes, he's simply the voice of his people that manages to reach Arthur and become his aide, helping him free the residents of Idyllis and lead them against Orm's forces in Atlantis. This is a re-imagined version of their relationship: Garth still becomes Aqualad, still joins the original Teen Titans, but now this is all happening against the larger backdrop of the coup against Atlantis. As Arthur retakes his throne, Garth is one of the first Atlanteans to begin studying sorcery, but it's his contact with Atlan that allows him to take up his new identity as Tempest. We've added the notion that his time with the ancient sorcerer is actually a time pocket, aging him four years within a matter of moments.
We've also simplified some of the relationship interplay involving Dolphin,as having Arthur in a relationship with her before she marries Garth is just weird.
Regarding his look, there's really not a lot to fix about his costume, as Jimenez did absolutely stellar work, but thanks to Teen Titans and Young Justice animated series there's a ton of fan art to look through. We happen to be fans of the work of deviantartist Bobkitty23, who did this cool redesign for Garth. if nothing else, he has very cool hair.
