Electricity runs within (Kyle's backstory)

Frozen

LET IT GOOOO LET IT GOOOO...no? Ok...
~~~~~
The stinging in my head turned into throbbing pain, but I felt weird new power flowing through my veins.

"IT FINALLY WORKED, THE LAST ONE WAS A FAILURE BUT THIS ONE WORKED!" The person yelled
Anger started boiling inside me as I remember all the good times and the bad times me and Gabby had together...she was my only family left. I pulled on the chains that are chained to my arms, restraining me from escaping. The anger flow through me and I felt the chain got colder as it shattered into a million pieces.

The scientist that was testing on me jumped in surprise as guards filled the room. T-they did this to Gabby...they killed her...NOW THEY WILL PAY! I felt myself letting everything loose, my anger, my tears, my sadness, and finally...my new found power. The whole room was covered in ice along as all the guards.

"WHY WOULD YOU KILL HER...WHy would you do that to her...she was my only family left." I grabbed the scientist by the collar of his shirt as I let loose all my tears I have been holding back for years.

"I-I..." The scientist was speechless. I knew it, they don't even care about us prisoners, they don't know how we feel. I focused on the ice and slow, his body started turning to ice as I dropped him and shattered his body.
