(Ki is something discussed very little on the show, but prevalent in martial arts. It is the life energy found in all things. Think of most of the powers in Dragon Ball Z, but less Energy blasting.)
Zaru had not yet burst out of the ground.
"As I Said: you rely too much on the air. You're a real air head. Do you really think you can find me just by sending little streams of air into the ground? I am a Martial Artist. I am in tuned with Nature. It'll take more than scientifically created moves like yours to stop me." He spoke, though the Airbender would not hear.
He had dug out of the ground, and appeared by a giant stone, equal to that of a pillar.
He began to lift it, roaring angrily. Placing the large structure on his shoulder with in-human strength, he tossed it at Alto, and Disappeared in a flash.
As the stone formation that resembled a pillar flew at Alto, there was a surprise inside...
Just as it was about to make contact, Zaru himself erupted from the middle of the stone from the inside, Proclaiming: "I AM The Building!"
The Firebender jumped out, and leaped at Alto in a feral rage.
"TENSHO! TORA HA KEN! (Flying Tiger Wave Fist)" Exclaimed Zaru. At the range Zaru gained from the leap, Alto could not dodge him. Blocking, or attacking would be useless: How do you block a hundred fists at once? No. They could not all be caught, Zaru knew, especially since they all appeared as after-images resembling a hundred at once.

"ATATATATATATATATATA!!!!!" Thundered Zaru, each ATA in sync with a punch. Every strike became faster and stronger with each blow. The strikes would hit the body mostly, the sheer strength rattling bones. And every now and then he'd toss plenty of strikes at the face.
"UUUUWATA!!!!" He Roared, tossing the final blow, as hard as he could, into Alto's Cheek. There was a flame engulfing this final strike. Hot it was, that flame, but it wouldn't leave any burn scars.
