A/N: Apologies for the long delay! Hope you guys enjoy this! :)

With Mikey out of danger...for now, the others immediately seized the chance to kicked the Shredder's allies out of the way. Slash stepped on Rahzar's foot and kicked him onto the ground. Fishface was kicked by Casey and Casey managed to land on the ground safely. He then used a hockey puck to hit Baxter Stockman in the face. "Buzzzzzz..." Baxter was overwhelmed by the sudden hit, causing him to let go of April. "Thanks, Casey." "You're welcome, Red. So, let's take these freaks down!" Casey smirked. "GOONGALA!"

The Turtles' Side
The Shredder rushed towards Raph to stab him but Raph dodged out of the way with an unnatural speed and pushed the Shredder forward. The Shredder slowed down to a stop when Raph kicked him again. The Shredder then landed onto a wall. Raph saw a katana hanging on a wall so he took it and rushed towards the Shredder. He lifted the katana and got ready to stab him. Suddenly, the Blood Stone was glowing. To his horror, a dark entity flew from the Blood Stone into Mikey's body. Raph collapsed as he felt the entity entering and trespassing into Mikey's soul. Raph hurriedly rushed after him, leaving Mikey physically unconscious.

Leo let go of Mikey when he felt that a darkness was approaching. "Guys, I sensed that...something is...coming. I don't like it." Donnie and Mikey looked around cautiously. Suddenly, they saw something dark entering. Donnie immediately wrapped Mikey protectively while Leo stood in front of them. "I am known as the Blood Spirit. For centuries now, I have been absorbing millions of pure souls, growing more powerful. The ones who wanted to possess my power did not know that I have been absorbing their life forces as well." The Blood Spirit said, slowly and eerily, while looking at Mikey hungrily. Donnie wrapped around Mikey even closer.

"Even though I have absorbed millions of souls, I am not satisfied with them. Why? Because they are not pure enough! I wanted the soul of someone who is completely pure and bright, with no darkness in the soul. You 3 were almost absorbed by me, when you were...killed, but you got lucky, as there are hints of darkness in your souls. I do not want a soul with darkness in it!" "So, what does Mikey have anything to do with this?" Leo shouted. Mikey started to whimper. Donnie soothed him by stroking his shell in soothing circles affectionately.

"Michelangelo has a soul which is bright and pure. I want his soul, so that I can finally reached my full potential and be freed from the wretched stone!" "Don't you dare think about it!" Leo shouted and rushed towards the Blood Spirit to kill it, but the Blood Spirit repelled Leo and sent him back by a long distance. "LEO!" Donnie yelled. "At last, turtle...It's time to meet your end." "Not so fast!" Donnie rushed towards Mikey and unleashed his blade. "Foolish turtle. You cannot hurt me or even touch me. No one can hurt or injure a spirit." Donnie got sent back by a strong force. "DONNIE!" Mikey shouted. "Now, turtle, prepare to meet your end!" As the spirit prepared to absorb the soul of a terrified Mikey, suddenly...

"GET AWAY FROM MY BROTHER!" Raph shouted and pulled Mikey away from the spirit. "Mikey, are you alright?" He shook Mikey's shoulders gently. Mikey got out of the shock instantly. "Raph!" He hugged Raph tightly. Raph returned the hug and shouted as he let go of Mikey. "Did that spirit hurt you? Did it do something to you? I WILL GET THAT THING AND..." "He...He was absorbing my soul." "What?" "He said that he came from this stone and he wanted to absorb my soul..." "Oh shell..." Raph thought. "This is worse than the worst."

"Don't worry, Mikey. We will make sure that this...thing will be gone, for good." "Thanks, Raph." They were then interrupted by a loud voice. "So, Michelangelo's brothers are attempting to rescue him? How touching...But pathetic." Raph instinctively shielded Mikey protectively. "I have all of the spiritual energy from all of the souls I've absorbed, but you have only one type of spiritual energy, which is your own souls. How can you hope to defeat me?" He taunted. "By doing this!" Raph and Mikey turned around to see Leo and Donnie using their own spiritual energies to hit him. The Blood Spirit yelped in pain.

"Hmm...your brotherly bond is stronger than I thought. Your spiritual energies contain this bond." The Blood Spirit commented. "But that won't stop me! I will just have to absorb all of you! I can get your bond and the soul I want! I can be more invincible and have the power to rule the world!" The 4 turtles instantly felt themselves weakening. However, the 3 all gathered up some strength to protect Mikey from it. They must protect Mikey from that Spirit...even if it means destroying their souls forever.

Suddenly, a feeling of warmth, protection and fatherly love entered into the atmosphere. "GET AWAY FROM MY SONS!" "Master Splinter!" They chorused as Master Splinter dodged an attack from the Blood Spirit and used his spiritual energy to hit him. The Blood Spirit fell onto the ground. "Sensei! How did you get here?" "I sensed a dark presence in the spiritual plane and found out that this entity is trespassing into Michelangelo's body. Michelangelo, are you alright?" "I'm fine, Sensei." Just then, the Blood Spirit climbed back up.

"This must be your master, turtle." He sneered. "I have to admit, he is more powerful than I thought. But, no matter." He gathered up his spiritual energy to hit them. "I will crush all of you!" "We must concentrate, my sons! Find your own spiritual energies and focus on them! You have as much power on the spiritual plane as his! You can do it!" The 4 sat in a meditative pose and channelled their energies. "Very good, my sons. Now, attack him with that energy!" They focused and struck him hard. The Blood Spirit was pushed out of Mikey's body.

Everyone's Side (Except the Turtles and Master Splinter)
Everyone was horrified to see the Blood Spirit groaning in the air. Just then, Leo took control of Mikey's body and struck that stone hard with the forgotten katana. The stone was immediately destroyed. Everyone watched as millions of white entities rushed out of the crumbled stone and flew into the sky. The spirits, after being locked up for centuries, are finally free and released into the skies above. The spirits vanished without a trace.

The Blood Spirit was also nowhere to be seen. Leo heaved a sigh of relief. Mikey immediately passed out physically. Just then, the building began to collapse. "Come on, guys, let's get out of here!" Casey yelled. Leatherhead carried Mikey's body out of the old lab. "NOOOOOOOOO!" The Shredder was then seemingly crushed by the stones and rocks. He never made it out. The MM and their enemies rushed out of the old lab. Just in time to see the old lab collapse into a pile of heap.

Hamato Family's Side
"We did it! It's over!" Raph cheered. "Yes, the catastrophe is finally over." Master Splinter smiled as Mikey moved closer to him. Just then, a spirit who looked like a soldier entered. "Donatello, Leonardo and Raphael, I have news from the Spirit King."
