A typical Metalbender
Metalbending aka Frikkin' sweetbending or Break-in Bending is one of the most BADASS bending powers to ever exist. Discussion is going on in the Avatarverse wether it is more BADASS then Firebending or not. The first Metalbender was freakin' awesome Registeel. Later, Toph figured it out and used it to break into houses, secret bunkers under capitols, bars, air-ships, banks, private bed rooms,etc. Metalbenders need to drink alcohol constantly, as their primary source of fuel.
