Explosion

"Close your ears," Stanley shouted behind him as he got ready to throw one of the fingers.

"What?" Red and Rey asked.

"Your ears," Stanley said. "NOW!"

He no longer cared if they listened to him or not and threw the first finger.

A massive sonic boom produced a shockwave that shook the three behind him. The finger he threw flew at an impossible speed, flying in the direction of the fire user, striking a tree about 8 meters to his left.

The finger dug into the tree, leaving a gaping hole at the back of it.

The man with the flaming hands looked to his right in shock, not understanding what had just happened. He turned around and saw Stanley and threw another fireball back at him.

'Dammit!' Stanley thought. With just one hand to use, his balance and thus accuracy had gotten so bad. It was the same last night too. 

'A little to the right,' he thought.

"AGAIN!" he shouted and threw another finger.
