Superfriends

Supergirl leads a team that operates in National City, of Earth-38. It protects National City from anyone who means to cause it harm, especially aliens. Kara Danvers/Supergirl is the leader of this team, which consists of Querl Dox/Brainiac 5, Hank Henshaw/J'onn J'onzz, and Alex Danvers. Supergirl's team also works with the D.E.O., which is the team's biggest ally. It was nicknamed "Superfriends" by Winn.

Year One: Becoming Supergirl
After Kara saved Flight 237 and revealed herself to the world, she wanted to use her powers to help people. She then revealed her true identity to her best friend, Winn Schott, who eagerly agreed to help her and keep her secret. He helped make her suit, find her crimes to fight, and even gave her some advice.

The team was expanded when James Olsen told Kara that he knew that she was Supergirl and that her cousin, Clark Kent/Superman wanted him to help her. Her team was then expanded more when she became allies and a member of the D.E.O., earning the help of Hank Henshaw/J'onn J'onzz, Alex Danvers, and numerous other D.E.O. members.

Cat Grant became an ally of Supergirl's team after the latter saved Cat, and the two became close friends.

Year Two: Alien Amnesty Act/Daxamite invasion
The daxamite Mon-El who crash-landed on Earth, became a member of Supergirl's team after he earned both Supergirl and the D.E.O.'s trust. He started training with Supergirl and became an agent of the D.E.O. before he eventually started going on some missions with Supergirl.

When Alex's relationship with detective Maggie Sawyer started getting serious, Maggie revealed that she had figured out that Kara and Supergirl were the same people. She then became a member of the team.

When James Olsen became the vigilante known as Guardian, he, along with his own team, became allies of Supergirl's team.

During the Daxamite invasion, Kara was forced to release lead into the atmosphere to force all of the Daxamites to leave. In an effort to save Mon-El, Kara sent him into away into space.
