Aang takes the place of markus as leader of the divergent, zuko takes the character of connor, iroh is Hank and azula and ozai are rk900 and Amanda respectively.

"Lieutenant Anderson, my name is Zuko. I am the android sent by cyberlife. I looked for you at the station but nobody knew where you were. They said you were probably having some tea. I was lucky to find you in the fourth tea shop."
Rk800 took a moment to inspect the store and the few customers who were in it.
No one had a criminal record.
"What do you desire?"
The person the lieutenant had been talking to ignored them in favor of cleaning the table in front of him, Iroh gave him a small look of recognition.
"You were assigned a case earlier tonight. A homicide, involving a cyberlife android." The lieutenant did not respond but made a grin that Zuko could not identify. "according to the procedure, the company has assigned a specialized model to help investigators."

If anyone is interested in making a fanfic with this idea, I'd love to read it.
