Pedro POV...

I walked into the main cell area as the door closed behind me as I heard what sounded like deep breathing "it was foolish to come here unarmed!" a familiar voice shouted which I soon summoned my powers which weren't very strong since I haven't unlocked my True Potential just yet. "Show yourself father!" I shouted as I heard deep breathing behind me which I turned around to see him,The Sliver Ninja,master of Balance and My father,Felix walk out of the darkness wearing a darker version of his original ninja Gi. "you,you have changed" Destro said "so have you,I don't want to have to fight you" I said which Destro leaped at me trying to strike me which I jumped up onto the railing. "Please,this isn't you!" I shouted "this is the true me!" Destro shouted before he sent several Oni energy blasts at me which I dodged them and leaped off the railing to land behind Destro "I didn't come to fight you" I said as Destro turned to face me breathing deeply as he looked at me with his red glowing eyes. "My father is in there somewhere,you saved me once,I'll save you now" I said "there's nothing left for you to save! your father is dead!" Destro shouted charging at me which I jumped out of the way as Destro punched the wall breaking it. He soon turned around sending several purple energy blasts at me which I blocked with my elemental powers "I have played many roles" Destro began hitting me with a energy blast. "Wore many masks" Destro said sending another energy blast at me "father" Destro said which I managed to block a incoming Oni blast "husband" Destro said as I was hit by a blast. "Brother" Destro said as I was hit by another blast as I tried to scoot away "teacher" Destro said as I was hit by another blast that sent me flying "but only one remained" Destro began. Destro sent another energy blast at me sending me into a nearby cell "destroyer!" Destro said in a evil tone before I ran at Destro and we began to have a fist fight before he grabbed my arm and threw me through a wall and into another room. I shakily got back onto my feet as Destro stomped in,I tried to summon my powers but Destro punched me several times sending me flying back into the main cell block. I got back up as I watched the man that was once my father stomp out and growl at me,I was about to summon my powers but I hesitated since he was my father but I suppressed those emotions before I summoned my powers and charged at Destro as we had a fist fight before he threw me away which I hit the ground hard before I got back up to see that Destro was gone. Suddenly Destro landed on the ground in front of me and grabbed my neck as I looked him in the eyes "you wouldn't hurt me,your son" I said which Destro glared at me "I have no son" Destro said before he threw me thought several walls and out the outer wall and outside landing hard onto the ground.

Meanwhile...    

3rd Person POV...

Inside the Prison...

Two Final Order Stormtroopers were walking down a hallway when something dropped behind them in the shadows as Green Glowing eyes looked at them as they heard a hiss "what was that?" one of the Stormtroopers asked as they turned towards the darkness as two snake heads similar to Karai's grabbed the two soldiers and dragged them away into the darkness. 

Meanwhile... 

Phenex smirked as he watched as Pedro was thrown through the prison wall when suddenly the door was busted down as several knocked out stormtroopers fell onto the ground and standing there was a Mutant serpent who looked just like Karai's snake form except they had glowing green eyes and was wearing some sort of vest that was green and black.

This mutant serpent's name was Kyle Kendall a Ninja alongside his friends the Ninja turtles,trained by Karai and her father Sensei Splinter,Phenex was about to pull out his sword but Kyle tail whipped him. "Cowabunga!" Kyle shouted throwing a smoke bomb onto the ground which exploded into purple smoke,Phenex coughed from the smoke as the smoke cleared up to reveal that Kyle was gone along with Char and Cosmos.

Meanwhile outside the Prison... 

Pedro was still unconciseness on the ground as Kyle,Char and Cosmos rushed over,Kyle looked over at the two serpentine "help me lift him"
