(This is Sofia and Mercury's origin Story (their ROTTMNT have a completely different one)

[Mercury POV]

I sat on The couch with my sister just watching some reruns of her favorite show. I took my eyes off her for a second then saw her dirty Blonde hair exit through the window I quickly stopped what I was doing and went after her. "Sof!" I whisper shouted.

"Mers look at these guys... Theyre all the same other are bots..." She whispered back. "What are they doing with that cat and Puma?"

"A puma? In Manhat-" I asked looking where she was and sure enough thise guys left that puma in a cage with a white cat in another. "Sof, we should go." I said grabbing her hand and heading back to our apartment but not being stopped by them.

"The Kraang must get the ones know as the ones who have speed on the ones known as Kraang." He said.

"Excuse me Sir we didn't mean to spy on you, we just were walking home. We'll forget everything we saw. promise."I said hiding Sofia behind me.

(Sofia POV)

"What?! We can't forget this! Does dad know about this?!" I whispered to him

"Snow, just trust me on this." Mercury told me.

"the ones know as the kraang does not believe you, you will come with Kraang" the man in front of us said while his buddies grabbed both me and my brother and dragged us to the puma and the cat. They made us touch them then spilt a glowing liquid on us. I tried not to scream in pain but I could barely hear my own thoughts when I looked ay my brother who was growling as his eyes turned to slots and started attacking the Kraang guys. He grew dark black fur on his body and his dark brown hair turned black while I grew white fur and my hair turned completely white I felt ears grow on my head and once all the pain was gone... I wasnt the same, but there was a constant pain in one of my arms

"So...fia.. Are you... alright?" Mercury asked with a robot arm in his mouth. "Sofia! Your arm!" Mercury ran to my side and held up... A stub where my arm should have been.

"It... It hurts Mercury..." I told him passing out from the pain.
