Ch 14 A Powerful Mind

"Donnie" April cried out, surprising everyone. "The figure is Donnie!" she cried out again. Leo and Mikey were caught off guard by their friend's words, causing them to be distracted. The figure used that to his advantage and swung his bo, hitting the brothers hard. Leo and Mikey fell hard to the ground and the figure went in to kick them. But Mikey thought quickly and grabbed the figure's foot and flung his sideways, sending him into Leatherhead. Leatherhead grabbed to figure and pinned his arms to his side, being careful not to hurt him. Leo then went and removed the mask from the figure's face. And to his shock he saw that it was indeed Donnie that was under the mask. "Donnie?!" Leo cried out, his blue eyes wide with shock. "What? I mean how.."

"Surprise Leonardo," Donnie said, his voice coming out rough and cruel. "Time to teach you your place." Leo gave Donnie a confused look. But before he could say anything suddenly Donnie broke free of Leatherhead's grip and slammed into Leo knocking him into Dr. Rockwell and sending them both to the ground. Mikey just stood there, stunned and confused to what was happening. Donnie looked over at his little brother and gave him a cold look. Before Mikey knew what was happening Donnie kicked him hard in the plastron sending him into Mondo, who was coming to help his friend. Then Donnie turned his attention to Karai and April, whose eyes were wide with shock and confusion.

"Donnie why are you doing this?" April cried out as she and Karai backed away from her friend.

"I'm sick and tired of being called weak and pathetic," came Donnie's cold growl. "Its time to show all of you just how strong and powerful I really am!"

"My friend," Leatherhead began, stepping in front of Donnie. "You are clearly not yourself."

"Oh but I am," Donnie growled, glaring at Leatherhead. "For the first time in my life I'm myself." By now Leo and Mikey had recovered from their blow along with Mondo and Dr. Rockwell.

"Dude what the heck is wrong with Donnie?" Mikey whispered, his blue eyes wide.

"I have no idea," Leo whispered back. Dr. Rockwell closed his eyes in an effort to read Donnie's mind.

"I believe I know the reason," Dr. Rockwell declared. But before he could get a word out suddenly the door burst opened and Slash and Raph came rushing in.

"Raph?!" Leo and Mikey cried out, shocked to see their brother there. "What are you doing here?" Leo asked, unable to hide to shock in his voice

"Just couldn't stay away," Raph declared with a grin. Then suddenly he was knocked backwards by Donnie. Raph fell out of his wheelchair and onto the floor. "What the Hell?" he mumbled pulling himself up. Suddenly more members joined the party. Rocksteady, Bebop, Tiger Claw, Dog-Pound and Fishface joined the group, all of them looking pissed. When Fishface saw Raph a sort of smile went across his scaly face.

"AH Raphael," he hissed as he made his way towards Raph, who was making his way towards his wheelchair. But unfortunately for Raph Fishface saw this and he launched his mechanical leg at the chair, shattering it. Raph whipped his head towards Fishface, glaring at the mutant. "Aw what's wrong Raphael?" Fishface mocked as he picked Raph up by the back of his shell. "Got no kick in ya?" Fishface laughed cruelly at Raph, who growled under his breath.

"No," Raph growled, balling his fists. "But I still got a Hell of a punch Scale head!" With those words Raph swung and with all his might punched Fishface as hard as he could sending him flying. Fishface dropped Raph in the process but instead of falling to the ground Raph flipped and landed on his hands.

"Yeah go Raph!" Mikey cheered. But his cheer was interrupted by Dog-Pound slamming hard into him taking him to the ground. "Arg my head," Mikey grumbled, rubbing his head. But the youngest turtle didn't have time to recover because Dog-Pound slammed him again, sending his skidding across the floor.

"Mikey!" Mondo shouted, running to help his friend. The orange skinned gecko hit Dog-Pound hard in the head with his skateboard, sending him to the ground. Dog-Pound let out a snarl and whipped around to face the gecko. "Cowabunga!" Mondo shouted, using a trick Splinter had taught him. He leaned back on his tail a sprung forward and with all his might he kicked Dog-Pound, sending him sailing across the room. "You ok Mikey?" Mondo asked, helping Mikey to his feet.

"Yeah I'm good bro," Mikey said with a smile, trying to hide the fact that his head was pounding. Just then the duo heard a thud and saw that Tiger Claw had landed a hard blow to Leo and Karai. But to their relief Leo and Karai quickly recovered and fighting together the brother and sister grabbed hands and jumped up together. Then they let go and spun in unison delivering incidental kicks that floored the assassin. "Way to go dudes!" Mikey cried out. Leo and Karai looked over and smiled back. Just then they heard grunting and saw that Leatherhead had just sent Rocksteady flying through the cement wall while April, Dr. Rockwell and Bebop were having a battle of their own. The monkey and warthog were delivering blast after blast while at the same time dodging the others blasts. Finally the pair succeeded in taking out the warthog. Dr. Rockwell distracted Bebop with his blast and April kicked him hard in the chest sending him to the group. Then redhead then delivered another kick, knocking Bebop out cold. Slash and Casey had gone to help Raph deal with Fishface.

"Lets take this bastard down!" Raph cried out as he grabbed Slash and Casey's arms for support.

"Ready for that trick I taught ya?" Slash asked.

"Hell yeah!" Raph cried. "Lets do this!" With that Raph pulled himself up on Slash's arm and they exchanged a look. Then Slash threw Raph launching his through the air. While air born Raph grabbed his sais and succeeded in taking out Fishface's legs in the process while Casey delivered a hard hit to Fishface's head. "Yeah!" he cried as he did a roll as he landed. But when he rolled Raph found himself staring up at Donnie. "Donnie.." Raph began. But he was interrupted by Donnie picking him up by his shell and throwing him hard into the ground. A crack was heard as Raph's shell cracked. Raph let out a cry of pain and Donnie was about to pound him again.

"No!" Leo and Mikey cried out.

"Raph!" Casey, April and Karai cried out

"Raphael!" Slash cried out running to help his friend. But before he could a voice cried out, "Enough!" Instantly Donnie dropped Raph and stood at attention. The group all watched as the Shredder walked into the room.

"Come," Shredder commanded, motioning towards Donnie. To everyone's shock Donnie obeyed and walked towards the Shredder. "Kneel," Shredder commanded. Donnie shocked everyone yet again when he knelt before the Shredder.

"Donnie what are you doing bro?" Mikey cried out, taking a step towards his brother. But Mikey swayed and nearly fell. Leo had to catch him before he hit the ground.

"Easy there Mikey," Leo said gently, steadying his brother. Leo looked over and saw that Slash and Casey were helping Raph get up and Slash held Raph off the ground. The rest of Shredder's goons had retreated when their master entered the room.

"I'm obeying my Master," Donnie replied without emotion.

"But D he's not your Master," Casey objected.

"He is now," came Donnie's cold response. "He should have been all along."

"What the Hell did you do to him?!" Karai shouted, glaring at the man she had once called father.

"He's under some sort of mind control," Dr. Rockwell informed the group. "I've been trying to break through it but no luck."

"Yes he's under my control now," Shredder said cruelly. "And nothing you van do will ever break it. He's mine now. And now you will see what he's capable of. Show them Donatello."

"Yes Master," Donnie said, going over to a button on the wall and pressing it. Suddenly the ceiling opened up revealing several rockets that were aimed at them. Gasping the group realized what was about to happen.

"Donnie no!" Leo cried out.

"Goodbye," Donnie said as he and the Shredder left the room. Once they were at a safe distance Donnie got out a hand held detonator and pressed the button on it launching the rockets and sending the room up in a series of explosions.
