My Brother's Best Friend

Prologue

It's my first year at Hogwarts with my brother, James Potter. He's in his second year along with his friends Remus Lupin, Sirius Black, and Peter Pettigrew. James is one of those overprotective big brothers who doesn't take shit from anyone who even thinks about doing something bad to their baby sister. My name is Kimberly June Potter. But the Marauders all have different nicknames for me. James calls me, Kimmy. Sirius calls me, Kimsy. Peter calls me, Ly (Lee). And Remus calls me, Kim. I was born on June 7th. That's why my middle name is June, plus my mom loves that name, she would've used Juniper but she hates that tree sooo...

"Kimmy, let's go! We have to go find Padfoot, Wormtail, and Mooney!" James exclaims. I roll my eyes.

"I still hate those nicknames." I reply. He glares at me. I usually just call them: Siri, Pete, and Rem. James is known as, Prongs, in the other three Marauders heads. But for me, I just stick with James or Moron. Sirius loves when I call James, Moron. In return, James likes to call me, Dork. James's friends stayed with us for Christmas and the summer. So I got to spend even more time with them. James once again snaps me out of my thoughts as he shoves me through the brick wall and onto platform 9 3/4. I growl and smack him in the back of his head when he comes through beside me.

"He deserved that." A familiar voice says. I look around until I spot Remus.

"Rem!" I exclaim and lunge at him for a hug. He laughs and hugs me back.

"Hi Kim. How've you been?" Remus asks as we make our way to the train.

"Good, how about you?" I ask. He smiles.

"Alright." He replies. I'm about to ask what's wrong when two more familiar voices speak up.

"I bet you he's alright because his Mum packed him loads of chocolate for the train ride!" Sirius exclaims, but only receives a punch in the stomach from Remus.

"Shut the hell up." Remus says, turning bright red. I laugh and James smirks.

"Well I happen to agree with Sirius." Peter says, earning a similar punishment to what Remus gave Sirius.

"Honestly you two. You need to learn when NOT to talk." Remus growls with a small smile. I roll my eyes and leave my cart beside the train and follow the boys on board. Suddenly, a blonde boy with a few followers walk up to us, blocking our way to the compartments.

"What do you want, Malfoy?" James growls. Malfoy smirks.

"Just wanted to find out why a gorgeous girl like her, would hang around you losers." Malfoy replies sharply. I glare at him.

"James happens to be my brother. And he's taught me plenty of unpleasant hexes. So if I were you, I'd step out of my way before I make your crotch hurt." I say with a sickly sweet smile. Remus chuckles and puts a hand on my shoulder. Malfoy looks at me in shock.

"How dare you speak to me like that, you filthy blood traitor." Malfoy growls. I pull my wand out and point it at him.

"Castreo." I say. Malfoy screams in agony, clutching his crotch, and collapses. I walk down the hallway with the Marauders behind me.

"You're bloody amazing." Sirius chuckles. I shrug and sit by the window in an empty compartment.

"I try." I reply with a giggle. James sits across from me with Peter next to him. While Remus sits beside me and Sirius on his other side. Malfoy stumbles up to our compartment and opens the door. I sigh and pull my wand out. I point it at him.

"Condolesco." I say. Malfoy groans and grips his head and stumbles down the hall. James laughs and high fives me.

"What the bloody hell was that?" Sirius asks me.
