Warner Brother's DC Universe is quickly growing and soon Aquaman, the King of Atlantis, will be joining Batman, Superman and Wonder Woman to fight crime in "Justice League" and possibly "Batman v. Superman." While Aquaman will play a role in the "Justice League" movie, it appears he'll be bringing some company along with him, his partner Mera, who will also be in "Aquaman."

According to the Hollywood Reporter, Amber Heard is in talks to play Mera in "Justice League" and "Aquaman." The former "Friday Night Lights" star would be the second actor to join "Aquaman" alongside Jason Momoa, who will play the DC Comics hero. "Furious 7" director James Wan has signed on to helm the film.

Before Mera makes her on-screen debut in "Justice League" in 2017, here are four things to know about the Aquaman heroine:

1. Aquaman's Love Interest

Mera is the wife of Aquaman in the comics and the Queen of Atlantis. Aquaman marries her shortly after he becomes King and the two of them have a son named Arthur Curry Jr., commonly referred to as "Aquababy."

2. Can Manipulate Water

In addition to having super strength, Mera has the ability to move large amounts of water and can even turn it into a solid to use against her enemies. She can also travel through different dimensions and has enhanced speed and reflexes. 

3. From Dimension Aqua

Mera was originally the Queen of Dimension Aqua. She left there and fled to Earth when a villain named Leron took control of the kingdom. Aquaman helped save both Mera and her land, but she chose to go to Atlantis instead when Leron was gone.

4. She Changes Following The Death Of Aquababy

A big storyline in the comics was the death of her and Aquaman's son. This causes her to become mentally unstable and ultimately causes a rift between the couple. Mera blames Aquaman for their son being killed by the villain Black Manta.

"Justice League" is expected to be released Nov. 17, 2017, while "Aquaman" is due out July 27, 2018.
