Aquaman bio:

Make all the sushi jokes, YouTube spoofs, and SNL sketches you want, Aquaman’s been an icon for over seventy years. The King of the Seven Seas. Reluctant ruler of Atlantis. A man who holds his own against heroes like Superman and Wonder Woman. He’s so recognizable that when officials speak about the perils of sea pollution, they’ll whip out Aquaman references to sound hip.

Cast out from Atlantis as a baby, Arthur Curry grew up on land, thinking himself a normal human. But when he matured, Atlantis returned, claiming him as their rightful king. Caught between a surface world constantly ravaging the sea and Atlanteans looking to lash out in revolt, he’s committed to protecting the entire globe. 
 

Aquaman is the king of all things aqua. He can breathe underwater, swim at tremendous speeds, and telepathically communicate with sea life. Being able to withstand ocean depths, he gets bonus points on land with his superhuman strength, enhanced senses, and nearly impenetrable skin. And although his courage and decisive nature have proven him a true heir to Atlantis’s throne, the continual conflict between land and sea makes him a citizen of both—and at home in neither.

Robin bio:

Every kid wants to be Batman, but do you have a lifetime of training? A billion-dollar fortune? The dream gets dashed pretty quickly. So OK, maybe you can’t be Batman… but that doesn’t mean you can’t be adopted by him. 

And just like that, Robin the Boy Wonder made the kid sidekick an icon. 

Acrobat Dick Grayson was the youngest member of his parents’ death-defying circus act. But after their cold-blooded murder, Dick vowed revenge. Seeing a genuine piece of himself in the boy, Batman took him in—and gave him a better outlet for his anger. Becoming Batman’s protégé, Robin is an expert fighter and astounding acrobat—with the toughest example in the world to live up to. But the Boy Wonder’s true strength may lie in not being Batman—and providing a beacon of hope and family throughout the Dark Knight’s grim crusade.

But as Dick matures into his own entity—eventually becoming the masked crime fighter Nightwing—Robin proves more than just an identity, but a mantle passed to the most worthy. From the troubled Jason Todd to the overachieving Tim Drake, the mask is now worn by Bruce Wayne’s own son Damian—a rebellious troublemaker who’s been trained by assassins since birth. With a lethal skill set and a marginal sense of mercy, Robin no longer needs Batman to protect him from criminals.
