She stood in the shadow of a hulking form that lay among the rubble in the canyon bed. She could scarcely feel a heart beat through all those loose rocks. Another step showed her the back end of a canyon crawler at the bottom of the pile and she assumed it must have been a serious rockslide to take them both down. She had heard the stories- those big-ass bugs were fugly, and fast.
Toph walked/slid around the rubble a bit to get a better picture of the scene and something seemed familiar about this guy. His size alone was unique. You don't meet a lot of people nearer to the size of a platypus bear than to a human. Even through all the loose rock she could tell some of the parts that should be bones and flesh were metal. Wait, is this...? She stepped closer and poked a toe at what should have been the torso. Heart was still beating, shallow but steady breathing- he'd live. She could feel something else too, much more faint. It was a slow rippling throb. It didn't remind her of anything she could think of but it seemed to be emanating from the head area. It couldn't be... Swiftly, she stretched her leg so a toe would reach the guy's face but decided to use the ball of her foot to pat around for the source of the strange minute vibration: beard... nose.. eye... and here it is between the eyebrows and the rest of the fore..head... bleeding hogmonkeys.
She (alright... the team) had fought this man before, and won, but she knew it had been pure luck that time. I mean this guy could shoot precision volcanic blasts from his 'third eye' while blocking attacks with his enormous bare metal limbs. Even with three master benders and a "warrior" that was hard to beat and they had barely escaped. Of course, that was before she invented metal bending. She knew she was a badass before, but now she was unstoppable. She considered waiting around for Combustion man to wake up so she could prove it. But, dammit, she had somewhere to be and if she hadn't promised to show by sundown she would have stayed to greet this big guy with a boulder to the forehead.
