Chapter 10? Wow.
7 hedgehogs stood outside a door about the times their size.
They had been attacked by Sonic and most of them had been knocked cold, then revived by Amy's CPR skills (She had been training to become a nurse). Twilight had come to the conclusion that Hadenya had etched a symbol of a dark god into Sonic, granting him unholy power.

They counted to ten and pushed the door open together. It was heavy- like trying to push a sitting Elephant. Amy now found herself standing on an island about an acre wide. The sky was red and it was connected to the churning lava below them with a thin stalactite that linked the bottom of the island to the depths of the red liquid.
"Show yourself, Hadenya!" Spark yelled, receiving no response.
Amy turned around, realizing the door was no longer there. They were trapped.
Spark threw his phone to Twilight and she pressed the button displayed on the screen. A few seconds passed in complete silence until the theme to Happy Tree Friends started playing loudly beneath them. Spark fist pumped.
"I KNEW that would be useful!"

Hadenya rose from the side of the island. His hair color had changed- it was now purple with a black aura. His body was the same color as this- he had no clothes but no sexual parts, and he had apparently stitched a heavy gun onto his right arm. He glared down at them, not impressed with the annoying racket emitting from what Spark had shot into his ear. He put his hand in and took out a tiny recording device, then proceeded to throw it into the lava.
"Pests." He said in a voice a little lower than, lets say, Brad Pitt's.
"Shut up and prepare to feel the burn- of a Goddess!" Twilight yelled, causing Hadenya to laugh.
"Know Goddess could defeat me! Ever heard of male dominance?"
Twilight scowled at this sexist remark. "What about The Sacred Four?"
"Ha ha ha! They DIED long ago!"
Twilight raised her hand into the air and snapped her fingers. Almost instantly four balls of light energy shot down from the sky and each one shot into Spark, Silver, Shadow and Amy's chests. It wasn't painful- just uncomfortable.
Amy suddenly felt a strong force inside her- The power of her guardian goddess, the Swan. She felt her energy ripple through her and could tell the other three felt the same.

Shadow, a trifle overconfident with this power, jumped forward onto Hadenya's face and struck him in the right eye. Hadenya shuffled back a little and threw a punch that Shadow dodged. Spark came in with Destiny on his back and launched her at Hadenya's groin (if he had one) and she struck him with a roundhouse kick. That area must have been sensitive, because he clutched it. He roared a curse and fired two lasers from his eyes.
Shadow narrowly dodged these but Spark wasn't so lucky- he was thrown back and almost skidded off the edge of the island.
Twilight extended to massive black wings from her back and her eyes turned white, and before Hadenya could react she was airborne with Silver on her back, who fired numerous balls of Psychic energy from the palms of his hands.
Shadow threw a chaos spear that hit Hadenya in the chest, making a hole that dripped with dark blue blood. Hadenya countered with a blast of dark energy from his hand that struck Shadow, who rolled back into Amy. Destiny was still in melee combat, and she jumped up onto the dark god's shoulder and pierced his eye with a knife. It popped like a balloon, but with more gore, and Hadenya swiped her off his shoulder, knocking her into the lava below.

Twilight veered right into Hadenya, knocking him back, and Shadow went straight in with a punch. The hole in the dark god's chest widened, and Shadow could see a dark blue heart, pumping slowly. He yelled his finding to Twilight, who through an orb at the heart. The orb blew up, but the heart withstood. It was tough.

Amy got angry. For the first time in her life, she was angry. Hadenya had badly hurt her friends and boyfriend and perhaps even killed Destiny, so she drew her hammer and ran forward. Straight at Hadenya, umping at the last minute, striking his heart with all her might. It twitched, shook wildly, the stopped beating and shriveled up. He stared at her in both shock and despair as his body slowly split and fell to pieces. Silent, who had been recharging Spark throughout the battle, stood up and walked over to Amy.

Sheesh! Long chapter!
Oh and don't worry, Destiny is fine! Sub-protagonists do not die!
