With a massive gap in time happening between Toph Beifong, being one of the greatest characters in the entire show, nevermind one of the best benders in the entire Avatar-verse, found herself quite busy after her adventures with the Aang gang to defeat the Fire Lord concluded.
As fans may , Toph actually discovered an entirely new form of bending during the series, being the first person ever to bend metal. By the time the events of help to fill in the story.
Not long after the final episode of Avatar: The Last Airbender, the comic series sees Sokka!
Through wild motivation and hard work, Sokka and Toph try to whip the students into shape, however, they have no luck and the day of the duel approaches fast. Realizing she is forcing her students to be something they aren't, just as her parents did to her, Toph decides to forfeit the school to the firebenders, however, her students seem to have a different plan. Something finally clicks, and her students come in bending metal coins through the air, hurling them around the room, ultimately winning the school in favor of the metalbenders. It is this school that eventually goes on to be the starting point that ripples into her future Republic City Police force.
Don't worry, Toph's time away starting an academy of her own isn't the end of her journey, and she links back up with the Aang gang to continue alongside them on more wild adventures as the Avatar: The Last Airbender comic series continues.
