Toph and Bumi are two of the most memorable and powerful heroes in Avatar: The Last Airbender, and over the course of the series, the two Earthbending prodigies repeatedly prove they're capable of taking down entire armies on their own when necessary.

But if the two ever came to blows, who would win a fight?

WHO ARE TOPH AND BUMI?

Toph was introduced in the second season of The Last Airbender. The young blind girl was quickly established as one of the most skilled Earthbenders around. Despite being the daughter of one of the wealthiest families in the Earth Kingdom, all she wanted to do is train, fight and use her incredible powers. Thanks in part to her blindness, Toph developed a closer connection to the earth that she bends, allowing her to feel it and manipulate it better than other Earthbenders. She also develops the ability to Metalbend, becoming the first Earthbender to do so before going on to teach those abilities to an entirely new generation of Benders by the time of the sequel series, The Legend of Korra.

Bumi is introduced early in The Last Airbender. In his youth, he was actually a friend of Aang. At some point during the hundred years since Aang was frozen solid, Bumi became one of the most powerful Earthbenders on the planet, joined the international secret alliance known as the White Lotus and became King of Omashu. He ruled there in relative peace until the Fire Nation finally invaded. When they did. Bumi surrendered without a fight. He revealed to Aang when he came to rescue him that this was because Bumi was waiting for an opportune time to strike. When the solar eclipse later negated the powers of the present Firebenders, Bumi single-handedly destroyed their installations and freed the city. He then joined with the White Lotus and took part in the battle to liberate Ba Sing Se.

TOPH VS. BUMI - ROUND 1

The two heroic Earthbenders have gone head to head only once so far, and that took place in the comics. "Bumi vs. Toph, Round One," by Joshua Hamilton and Johane Matte, was first released in the Nickelodeon Comics Club magazine before eventually being reprinted in Avatar: The Last Airbender - The Lost Adventures. The story takes place during the events of the final episodes of the animated series, just before Sozin's Comet flies overhead and empowers Firebenders all around the world. While preparing for the final battle with the White Lotus, Suki is amazed by the story of Bumi liberating Omashu single-handedly. She even calls Bumi the greatest Earthbender who ever lived.

Toph overhears this and mocks Bumi for believing that, leading to Sokka setting up a duel between them to show who's more skilled. The pair prove to be evenly matched, with their battle becoming so destructive and powerful the other members of the White Lotus fear it'll give away their position to the Fire Nation. Everyone else has to break up the battle. Sokka - who'd been acting as a referee for the fight - decides it'll have to just count as a draw. Bumi and Toph both get excited at the prospect of a "round 2," although this battle has never been shown.

WHO WOULD WIN ROUND 2?

But who would actually win in a supposed second battle? Both Bumi and Toph claim during their duel neither of them is using their full powers. This is likely true, considering the kind of damage both of have them proven to be capable of in the past. Bumi brought down an entire city and army on his own, and with relative ease. But Toph is about as powerful, and she has a number of advantages Bumi lacks. Toph's inherent ability to follow feel the earth around her should give her a natural advantage in any duel with another Earthbender. Her Metalbending prowess also gives her an ability that Bumi really has no actual counter for.

Perhaps the most important indicator of the battle comes from the fact Toph hasn't necessarily reached the peak of her abilities yet. Toph becomes a recurring presence in the fourth season of The Legend of Korra after having spent the time-skip between the two shows being the chief of the Republic City police department. She's revealed to have become even more powerful, developing a connection with the entire world by using the roots of the Spirit Tree. Bumi's powers might make for an interesting and difficult battle, but it's unlikely Toph couldn't keep up with Bumi - especially after she further developed her abilities.
