3rd POV
Salem went to punch Y/N who blocked it with his giant claw and he then punched her in the face, for the first time sending her flying. Y/N looked at his fist in shock, he then looked up and saw Salem hurdling towards him, readying a massive punch. Y/N transformed back to normal and dodged it. Her eyes glowed red and she grabbed Y/N by the neck.
Salem: you think you can defeat me! I am a god to you!
She threw Y/N over the buildings and into the ocean. In the ocean he transformed into the Behemoth. Salem walked towards him and was cracking the bones in her body. Y/N looked down to her and slammed his giant claw into the ground. She lifted one hand and moved it to the side of her. She jumped on his arm and ran up it, making to his face and kicking him, sending his body into the water.
Salem: you need to know the nerves of your monsters, though a powerful creature, can't take a hard blow to the jaw.
Y/N got up and roared at her, it began shaking the city, making the Grimm and the teams look around. Glynda heard the roar.
Glynda: Y/N....
Y/N's eyes began to glow red.
Salem: nice to see you're learning this one, incredibly hard to study....Shame it's wasted on you!
He shot a bright fire blast at Salem, completely engulfing her in the flames. She absorbed all the fire and put it into a ball. She then shot the ball at Y/N, punting him in the face and making him fall to his back. Salem started moving her arms in a circular pattern and a black cloud went over Y/N. A huge purple lightning bolt came down and impaled Y/N in the chest, making him roar in pain. The bolt just sat there, until another one came down and impaled his shoulder.
Salem: well i'd like to say it's been fun Y/N, but we both know that would be a lie.
The cloud moved above his head and Salem smiled. From behind 3 purple shots hit her in the back.
Salem: what the?!
She turned around to see Glynda in a battle stance.
Salem: Glynda, how's your ex husband?
Glynda: let go of the boy!
Salem looked at Y/N and then back to Glynda.
Salem: why should I? He's fought and lost.
Glynda remained silent.
Salem: oh I see, this boy is not just any boy, he's your boy.
Glynda tightened her fist.
Salem: That's so....pathetic, you haven't changed a me damn bit.
Glynda: you are no god.
Glynda fired more shots at her, though Salem easily reversed it and fired it back at Glynda. Glynda was knocked back into a tree by the hits. Y/N got up and transformed into Deathipede and clamped on Salem's shoulder.
Salem: What a pest you are!
She grabbed his head and slammed him onto the ground. Glynda punched Salem in the face. She quickly recovered and backhanded Glynda, opening her up for another bite from Y/N.
Salem: we are not playing this game!
She put both hands out and blasted both Glynda and Y/N. She walked over to Glynda and stepped on her wound.
Salem: you used to be so tough, tell me, how many civilians did you lead to their deaths?
Glynda: I evacuated them!
Salem: really?
Salem snapped but nothing happened.
Y/N: !esol uoy ,melaS revo s'ti ,mmirG eht nwod koot smaet eht ekil skooL
He transformed back to normal, he had cuts all over his body and was bleeding.
Salem tightened her fist and blasted Y/N's shoulder, sending him back.
Glynda: Y/N!
Salem: as for you!
Salem picked up Glynda and pulled out a black sword. Y/N looked up to see Salem holding his mother. Salem thrusted the sword forward and put it through Glynda, making her scream in pain.
Y/N quickly got up and ran towards Salem and transformed into Tripion.
He tackled Salem, making her let go of Glynda and the sword. Y/N was roaring and screaming as he attacked Salem. She couldn't move, his attack's were so fast and strong, he held her into the ground with his stingers. His middle one came up and went right through her head. Salem's body twitched with the hit. Y/N transformed back to normal, being followed by the pouring cold rain. Y/N quickly ran to his mother and went to the ground with her.
Y/N: Mom! Mom! Stay with me mom, please!
Glynda: Y-Y/N.....you....you did good.
Y/N: save your strength! I'll take you to a hospital.
Glynda: don't....it's too late for me....I know I haven't been there....I want to apologize, I love you Y/N, no matter how old you get you will be my little boy...I'm proud of you....
She placed her hand on Y/N's face, he held it there as she gave a light smile, she then closed her eyes and let out on final breath. She went completely limp in Y/N's arms. Y/N was trying to fight it, but he couldn't, he felt tears running down his face, he hugged his dead mother. In the distance Summer watched, she watched as Y/N was grieving over Glynda. Everyone was on the city's edge, no one dared to break the two up, their last moment together was in her death.
