Aggressive Fight

(Flashback 10 years ago)
There was once a pink hedgehog who lives with her two older brothers. Although they lived at the same street, the two hedgehog kids were not good friends at first, they were bitter enemies. Sonic likes to pull pranks on Amy most of the time and it really gets her angry. But with her brothers Silver and Shadow, they are always there for her.

Amy Rose was at a flower field picking up flowers, she made a flower crown of some flowers and put it on her head.
A butterfly flew around and she held up her finger to let it land on it.
"Aww aren't you beautiful little butterfly?" Amy sighs cutely and let it fly away. In a bush nearby, Sonic was sneaking on her.
"Hehehehe… she's so gonna get it" Sonic giggles quietly in the bushes. He then pounced on Amy and rolled in the flower field.
"Peek-a-boo Ames" Sonic said as he laughed. Amy was not amused and brushes off the dust from her orange dress.
"SONIC! How many times do I have to tell you to leave me alone or else I call my brothers!" Amy yelled at him. Sonic gets frightened when she mentions her brothers, for last time, he got his butt kicked by Shadow when he insulted Amy.
"Okay okay, I'll leave you alone for this time Ames" Sonic said as he leaves. Amy glares at him for a moments and takes on her flower crown.
"I hope he'll not be a jerk for all time" Amy said grumpily. She continues to pick flowers and when she's done, she walks her way home to her family. She gets to her room and cuddles with her dolls. Her 2 year older brother Silver came in.
"Hi Amy, how's your day?" Silver asked his sister. She looks at him and frowns.
"Great, except that Sonic joking with me and nearly sabotage my flower crown" Amy showed him her flower crown.
"Oh, it looks nice sis" Silver said, rubs her back in comfort as she hugs him. She snuggles in his chest fur while hugging him.
"Shhh, relax Ames" Silver said, still rubbing her back to calm her down.
"I hope he changes someday"

(10 years later)
Sonic, Amy and Silver are now high school students while Shadow is going to college of art. When it comes to school, mobians are not allowed to use their powers in class. If they did, they would get a detention. Amy's first schedule is biology where she has her brother Silver for class. As she gathers her things for class, her ears perk up hearing someone approaching towards her locker.
"Hiya, pinky. What you have for class?" Amy didn't look at the student who talked to her.
"Just biology as usual" Amy mutters.
"Ah, I have that class too" the male student said. As Amy closed her locker, she saw it was only her enemy Sonic the Hedgehog.
"Hmph, see you there" she grumbled and walks away to get to class.
"Hey, wait for me Ames!" Sonic is about to follow her when he got stopped.
"Why are you still bothering that pink loser, Sonic?" a female flirty voice came up to him. The blue hedgehog growled lowly that he really doesn't want to see, Sally Acorn his Ex-girlfriend.
"Sally, I didn't expect you to interrupt my way to class" Sonic sighs and walks away to come in time.
"Hmph, what does that pink bitch have that attracts my Sonic? Grrfff!!!" Sally walks away to get to class.

At biology class, they were studying about diseases like stroke. Amy sat next to her brother Silver.
"As you know all, stroke is a disease that can cause damage to the brain and I'll show you the symptoms of it" the teacher showed a pic of a healthy person and a stroke victim. Amy grimaces when she saw that the stroke victim looked paralyzed. Her brother is the high honor student and the smartest one in Mobius High School. Sometimes he gets picked on by jealous students and they usually call him a 'nerd'. But he ignores them mostly until he loses his temper. Amy was disgusted at the stroke pics.
"Man, this is gonna give me nightmares, bro" Amy said quietly to her brother.
"I know, but shhh" Silver whispers to Amy while doing his notes. Amy groans in annoyance and continues to take notes.

After School, Sonic stands next to a lamppost, waiting for Amy.
"Man, I just need to tell her that I'm done playing pranks with her, today its karate" Sonic sighs, still waiting.
He saw her coming along with her two brothers. Shadow is already a black belt but Silver and Amy are still brown belts. Even Sonic.
"Oh hi guys, what's up? Ready for training at the karate club?" Sonic asked the three.
"Yeah, yeah. Whatever, Faker. But I'm keeping my eye on you" Shadow growled lowly at his rival.
"Okay jeez, I'm just happy that I train with you guys, you're good as me, the fastest thing alive" Sonic said. He goes up to the three and group hugs them.
"Get off me, Faker" Shadow growled, he so wanted to punch his face.
"Whoa, whoa. Easy Shadow, I just admit it's nice to train with you all at the karate?" Sonic smiles. They all walk their way to the karate club.
"Hmph, he may have changed but I still don't like him" Shadow grumbled.
"I agree with you, big bro. Maybe we'll get to understand him more often" Silver said. Sonic was listening to them but they didn't know.
"What do you say, sis? Should we be his good friends?" Shadow asked Amy. Amy rolled her eyes and answers.
"I don't know Shadow, maybe" Amy said. They arrived at the karate club.

Much later, Amy is now challenging Sonic. They bow before the challenge and get into fighting position. Espio was the sensei.
"Get into fighting stance!" Espio tells them both.
"HYAH" Sonic and Amy got into their fighting positions.
"HAI!" Espio shouted again, telling them to fight.
They both circle around for some room, Amy punched him in the chest but Sonic blocked it and 'kyah' with a kick.
"Is that all you got Ames, I'm just getting warmed up" Sonic said.
"You just wait, Sonic" Amy responded. Sonic did some sweepkicks and chops at Amy and she did some blows. Then he knocked her down the floor.
"Score, 1 to 0. Round 2!" Sensei Espio said. Sonic and Amy both block and kicks at each other as well karate chopped. Then Amy grabs his hand and threw him over.
"Who's the tough guy now, Sonic?" Amy taunted Sonic. He gets up does a right block with his arm and punches her gut hard. She holds her stomach and gets angry.
"GGGRRRR!!!!!" Amy was now pissed off, she fights back in an aggressive attitude. Sonic's pupils shrunk in fear.
"Whoa, whoa, whoa! Easy, Ames!" Sonic blocked her punches and kicks. She was still angry and did a blow to the right side of his torso.
"OW! Amy what the hell is...Whoa!" Sonic dodged another attack
At the stage, Silver and Shadow watched in total shock.
"Don't do it, sis!" Silver shouted. But Amy was too angry she didn't heard.
"AMY! FOR HEAVEN SAKES STOP!" Espio tries to calm Amy down.
"Hmph!" Amy calms down and stops.
"Amy Rose! What got into you!" Espio asked her sternly. Sonic glares at her, holding his right side of the ribs, he also got a black eye.
"I lost my temper" Amy answers.
"Well guess what Amy, you're out!" Espio signed for 'get out'. Amy sighs in defeat and walks away. Her brothers where disappointed at her.
"What a challenge" Sonic said.

Much later at Amy's home, Silver and Shadow were having a talk with their sister of fighting Sonic so brutally.
"Amy how could you do that! He didn't mean to!" Shadow yelled at her.
"I...I…I'm sorry" Amy whimpered in fear.
"Shadow, calm down! You're scaring her!" Silver said to Shadow. He looks at him and calms down.
"Sorry, but Amy, why did you go berserk on Sonic? He's our friend, remember what we said. The old times is over, you live in the past Amy" Shadow said, more calmer.
"I don't know, okay! I just don't like him and I don't know if I can trust him. You know how he always pulls pranks on me when we we're kids. You're right, I live in the past" Amy sobs out loud.
"Amy, I think you need to apologize to him, I told you 10 years ago he would change" Silver said.
"I don't know, guys. He might not talk to me ever again and I just beat up his ass badly" Amy sobs again, "I can't let anyone see me at school tomorrow" she ran upstairs to be alone in her room. Silver is about to follow but Shadow stops him.
"Let her be alone" Shadow told Silver, he nods.
"We'll talk to Sonic tomorrow" Silver said and gets to the living room.
At Amy's room, she's still sobbing for beating Sonic.
"I'm sorry Sonic, I didn't mean to beat you so badly. I forgot the discipline rule in karate" Amy said sadly.
