This is a one shot, sorry for Mikey's OCC
Normal POV
Mikey was always called 'wimpy' by his brothers, especially Raph, just because he was the youngest.
"I am not wimpy!" Mikey shouted, Raph shrugged, he tackled Raph to the floor in anger
"Oh, you wanna play this game?" He said tackling him back on the floor, until Donnie and Leo finally pulled them apart.
"Woah, what happened?" Leo asked, pulling Raph off of Mikey, while Donnie was trying to pull Mikey away "Mikey stop!" He calmed down
"Now, What happened?" Donnie said, still holding a slightly raged Mikey.
"I just called Mikey wimpy, which he is!" he casually said, and Mikey got outa Donnie's grasp and tackled him again
"How's that for wimpy?!" Mikey said as we got him off again
"Calm down!" Leo said, and glared at Raph "Apologize Raph"
"No i'm good" he said stubbornly, Leo sighed and looked at Donnie to let go of Mikey
Mikey walked to his room and slammed the door, they shot a glare at Raphael "What he is!" Leo sighed and shook his head
Mikey POV
Mikey has snuck out of the Lair Into the rooftops to think when he found the Foot, Fishface and Dogpound, but instead of calling my brothers I fight by myself
"Hey, fishface, Dogpound!" Mikey shouted hiding in the shadows, Dogpound sniffed the air.
"Ah, Michelangelo found you" Dogpound said, pointing toward his hiding spot and the foot started attacking him in his area
Though he could attack them easily, they were multiplying in tens and we're getting harder to fight
"Oh this isn't good dude" while one foot bots kicked him in his arm and he squealed in pain
"I'm outa here!" He said, and pulled out a smoke ball and threw the ball on the concrete ground
Back at the lair
Once Mikey got back to the lair there were two injuries, the one on his arm and three was a small cut under his eyes, he hopes his brothers wouldn't notice the eye cut, and it wasn't much of a help that he was holding his hurt arm, even though it hurt like heck.
"Mikey, were did you come from?" Leo asked, Mikey shrugged and sat on the couch "No I mean, where'd you go" Leo
"On a rooftop" he said casually, still holding his arm.
"And what's wrong with your arm?" Leo said suspiciously, getting up to sit next to him.
"Nothing, why would you ask?" He chuckled, starting to sound like he was lying, the others caught up to the conversation
"Like Leo said what's wrong with your arm?" Raph bud into the conversation, crossing his arms, Mikey looked at Raph and glared the anger came back
"Yeah" Donnie agreed
"Guys! Just stop asking already! God!" Mikey said in annoyance, his brothers were taken aback by this "Look I'm sorry for snapping just please stop asking" he quickly apologized, the others looked at him and said
"We'll forgive you IF you tell us where you were and what happened to your arm" Mikey sighed in annoyance
"Fine, but don't call me wimpy RAPH" Mikey said crossing his arms, Raph nodded
And he told his brothers everything "What first of all you weren't even supposed to be out! Second I'm glad you're okay little brother" Leo said putting his hand on Mikey's shoulder as did Donnie
