Nathan, Luke, and Hannah didn't get along at first. The first person that Nathan met between the two was Luke, him and Luke were friends ever since Nathan started to live with his father, Nathan and Luke didn't get along at first, both  fought a lot as kids, but as time passed, the two grew to become closer, becoming the best of friends. Going in many missions together as the new Robin and Superboy, the two always had each other backs, Nathan defending Luke and vise Versa.

During a mission, Robin and Superboy, who is indeed Nathan and Luke, were surrounded by female warriors. Nathan and Luke were holding their own against these female warriors, even defeating most of them, but they all suddenly stopped fighting and stood back after hearing the voice of a female.

Nathan and Luke were prepared to fight this enemy, believing it was probably the leader or someone equally as dangerous, both serious about it. What they saw wasn't what they expected, it was just a little girl, probably younger than them, definitely shorter. They both were confused, Luke chuckling and laughing of course and Nathan just arching his eyebrow.

They looked at each other, then back at the girl, telling her to run away before she gets hurt, but of course...it didn't go well for the two of them. Both of them were beaten pretty easily, they both were confused, how come they couldn't this little girl, she was about to kill them both with the slam of her blade, then a voice came out screaming for her to stop, and that's what she did, finding out the person who told her to stop was Donna Troy.

During the Circe invasion on Earth, Luke and Nathan helped Hannah battle the bestiamorphs working together as a trio as they defeated a general of this army of beasts. Once the two were separated from Hannah, they informed Donna and Cassandra to find her, and so they did.

After that battle, she left, returning to themyscira, but not before giving them both hugs. Nathan and Luke believed that would be the last time they'd meet their new friend, but they were wrong. Hannah came to them, asking for help to find her mother who was taken by Ares, the god of war.

That battle was heavily difficult for them, if the three didn't have each other, they would've all died, working together by defeating monsters, warriors, and many more to find her mother. All of them would be talking about their childhood, and their origins, but Nathan wouldn't tell them about his mother

After days of adventuring, they finally found Diana of themyscira, the four of them faced Ares, who informed Hannah that she was his father and that Diana wasn't her real mother. The battle wasn't easy, Nathan and Luke were brutally getting beat down, while Ares used some sort of spell to make her watch as her friends were going to die, but Hannah would beg for Ares to stop, but he wouldn't, due to her being enraged, she was able to break free and attack Ares. Ares released Diana and escaped, telling his daughter that they would meet again.

After that, Hannah, Luke, and Nathan would become the best of friends, working together on many missions as Robin, Wonder Girl, and Superboy for many years to come.
