Hello everybody this is my story of Yakko x reader here's a crossover of teen titans go and tmnt 2012 one-shot.
You felt Raph gripping your arm. Starfire felt concern about you. "Hey (y/n)." Donnie and April greeted. They notice a black eye. "Gees what happened to you?" You covered your eye. "Oh I just got hit by a door when Raph came by accident. You lied so no one what happened. Yakko noticed what's going on with you.
(Time skip).
Raph kept pinning you and punching you. "If you tell anyone I did this too you. You'll get one more black eye. Understand?!" You nodded. Raph then grip your arm. "I said fucking understand?!" You nodded. "Yes!" "Good." He harshly pushed you.
(Time skip).
Raph goes back to the sewers, you lived in your apartment.
  You looked at the mirror. Trying to cover the bruises with foundation make up, you hissed in pain. You felt tears prick in your eyes. "What happened to you?" A voice startled you. You spun around and saw Yakko leaning against the bathroom wall. "Don't do that you gave me a heart attack." You said. Yakko notice something dark on your arm.
"Are hiding something from me?" He ask. You covers it with your black sleeve hoodie. "N-no I don't." You lied as you walked past. Suddenly he grabbed your arm. As he pulls the sleeve down to reveal the bruises you have. "Did he hit you?" Yakko asked concerned. You hugged him tightly. "He did just don't tell him!" You cried on his shoulder.
   Then Yakko hugged you back soothing you. "Hey everything going to be okay." Yakko said.
   "I'll protect you." You sniffed. Looking into his dark eyes to your (e/c) eyes. "You will?" You ask. "Yes." You smooch him on the cheek. "Thank you." "You're welcome."
  (Time skip).
Raph goes in your apartment looking for you. But stopped by Yakko standing in front of you.
   "(Y/n). You got to take somewhere." "(Y/n) not going anywhere with you." Yakko cross his arms. "She had enough with your abuse. You hit her, beat her. Not cool." You  hid behind Yakko. Scared of Raph. "You leave (Y/n) alone if you don't leave her alone. This will be pain with my fist." Yakko cracked his knuckles. Raph humbled as he went home. You sighed in relieve. Yakko held you close.

  In bed. Yakko took off his jacket exposing his green shirt. You laid on the bed peacefully. Yakko rubbed your back gently.
  "Good night (y/n)." He said as he kissed your forehead. As he laid on your bed. Protectively.
   (Time skip).
You recovered from your bruises. After that you came in with your friends, April Casey, Donnie and Mikey.
  Yakko came with bruises and his shirt with tiny holes. You gasped covering your mouth. "Yakko! What happened to you?!" You ask worriedly. "Oh it's just Raph came to fight with I fought back. But I'm going to be okay."
   Yakko hugged you as you unconsciously laid your head on his chest.
   "I love you." Yakko chuckled. "I love you too (Y/n)."
