A Teen Lantern (Hal Jordan), Aqualad (Arthur Curry) and Wonder Girl (Diana of Themyscira) redesign submitted to Project Rooftop.
Teen Lantern is Hal Jordan. He is the new recruit of the Green Lantern Corps and he must become the Green Lantern of Earth when Alan decides to retire. But in the meantime, he'll be trained by Alan. His costume is green and black like Alan's but the Lantern is spread all around it, like a circuit that empowers the uniform, more like the Flash's.
Aqualad it's the King of Atlantis and that's has to be part of it's costume. What he wears it like a diving suit, with an armour with two flippers, somehow similar to Alan's. However, he doesn't wear a mask because, like Flash, he doesn't feel like a hero at all: He is the king of the seven seas after all.
The same happens with Wonder Girl. He is an Amazonian princess. Like Ted's she wears a bodysuit armour with very few ornaments: the skirt or the crown.
