A six year old Casey threw a ball back and forth to a 7 year old boy with brown hair and light blue eyes.

"Mark catch my throw !" Shouted Casey excitedly.

"I'm ready" Mark responded bending into a position getting ready to catch the ball. Casey thew the ball, but it accidentally flew over the fence and bounced towards a stone wall.

"No !" Casey shouted. "I lost the ball again !"

Mark calmly glanced over the fence. "I'll go get it".

"No !"

Blinking, Mark turned his head to regard Casey for a moment.

"There's a demon rat over there!" Casey was now clinging onto Mark's arm crying.

"Don't worry I'll be back" Mark said as he ruffled his hand across Casey's head. Mark flipped himself over the fence glacing around until he caught sight of the ball. He grinned walking up to the ball picking it up.

A shadow suddenly loomed over Mark as his eyes widened as glanced up. He let out a scream seeing a ninja dressed in black grasp him along with other ninjas as they dragged him into the shadows as he screamed and thrashed. Mark felt darkness begin to cloud his vision as he's dragged further into the shadows.

"LET ME GO!"

"Mark ?" A little voice was calling from the other side of the fence.

"Casey !" Mark screamed seeing his brother desperately trying to climb over the fence despite his shortness.

"Mark!" Casey screamed as tears fell down his little cheeks with his little hands grasping onto the edge of the stone fence. Mark was dragged into the shadows until he could no longer see his little brother anymore...

10 years later,

Casey walked with April to meet up with her new boyfriend.

"I still can't believe you chose this guy over Casey Jones" Casey jokes.

"Well he's very kind and relabe" April comments.

"Hey I'm kind when I want to be" Casey argues.

April frowns. Casey sighs. "Look if he makes you, than I'm happy for you" Casey said. April smiles.

"Thanks Casey, I think your gonna like him" April said.

"I'm sure I will" Casey chuckles. Casey then felt his T-Phone beep. He takes out his phone and looks at it.

"What's wrong ?" April asks noticing Casey's face change to concern.

"The guys need my help in fighting off some kind of threat" Casey replies.

"Are the guys okay ?" April asks concern.

Casey shrugs. "I'm sure they are April, but I'm gonna check this out" Casey said as he leaves.

***************************************************************

Casey runs rooftop to rooftop. He was now in his vigilante outfit. He finally spots The turtles fighting a Black clad ninja with sliver outlines on his uniform and five other ninjas. Casey jumps down to the roof.

The ninja with the sliver outlines throws a fireball at Raph, which hits his shoulder. Raph hits the ground, holding his brunt shoulder.

"Hey creeps nobody hurts my friends and gets away with it !" Casey shouts.

The black clad ninja glares at Casey.

"What have theses freaks ever done for you more than family ?" The black clad ninja asks in a gruff voice which had a slight Japanese accent.

Casey raises an eyebrow at that question but decided to answer it.

"There not freaks there my friends !" Casey shouts. "They've always been there for me when I needed it" Casey shouts proudly.

The black clad ninja seemed upset at that response. He singles his foot ninjas to attack the turtles harder. One of the ninjas hits Leo to the ground with the butt of a sword.

"Leo !" Mikey shouts.

Casey growls as he attacks the black clad ninja. The black clad ninja dodges the attacks and punches Casey to the ground. Casey falls to the ground.

"I'll let you off with a warning, Casey stay away from theses freaks" the black clad ninja warns.

Casey eyes widen when the ninja says his name.

"W-who are you ? Casey stummers.

The black clad ninja takes off his mask to revile his face. Casey gasps. The ninja had Brown spiky hair and light blue eyes. On his left cheek was a foot clan tattoo. He looked to be 17 years old.

Casey felt shock to his core. The brown haired boy stares at Casey with an emtionless expression.

"M-Mark ?!" Casey chockes out.

Mark nods as he disappeares in the shadows leaving a shocked Casey behind.
