LOK: Book Air, Chapter 9 “Hey did you notice this…?”
There’s a character in Toph’s elite police force that looks oddly familiar…

Hello.. LONGSHOT.

That’s right, check it.

Nose and facial structure.
Bushy brows.
And I know about, mm, most of you are thinking, “But he’s not an earthbender and can’t metalbend. He can’t be a cop.”
Who’s to say that the earthbender/metalbender rule was always around? Or for that matter that only benders are allowed in the police force?
Spoilers from ATLA: The Promise Trilogy? Maybe. ;)
When Toph is arresting Yakone, her eyes are CLOSED.

Still has six fingers.
If you listen closely during the trial, you’ll notice that the lawyer and adult Toph both their share voice actress (the lovely Kate Higgins for those who didn’t know).
