Silver Age Seattle
The youngest of the Blackstones
Aquamarine is even younger than Copper, and has yet to even join the team as he has not yet reached age 20, when the family accepts a metahuman member into the a team. Still, he is engaging in training at this time, and he appears to be a promising member. With the ability to transform his body into water in any state — steam, liquid, or ice — he has potential to be one of the more powerful members of the team when he does join. He’s eager to please his family, and looks up to Iron with a sense of awe.
He was not a member of Alchemy, and is earger to test himself in battle.
