Robin- Earth 2 (The New 52)

First Appearance: Earth 2 (2012) #1- The Price of Victory

Robin, aka Helena Wayne, was the daughter of Selina Kyle and Bruce Wayne, who became a vigilante and protector of Gotham City like her parents.

In the final days of the Apokolips War, Robin was asighned by her father to protect him from the Batplane as he scaled the Apokoliptian Command Tower, shooting down any Parademons that tried to kill and stop him. When Batman reaches the central control of the tower, he tells her to get away. She tries to argue saying that she needs to pick him up, but Batman reveals the full extent of his plan, that once the virus has been uploaded the tower will activate a failsafe that will blow up the entire tower. She asks him not to do it, but he tells her that he has no choice and calling her his "brave, wonderful soldier" tasks her to live for him. With a final "I love you" Batman uploads the virus and finishes the Parademons. 

Supergirl arrives seconds later and she tearfully explains that Batman, Superman and Wonder Woman were all dead. But Supergirl points out that they succeded in stopping the Parademons, who are falling out of the sky. They suddenly see a Boom Tube and fly towards it, thinking it was Steppenwolf, but realising it was someone else
and going through it, destryoing the Batplane on impact.
