You were sorting out your equipment in the locker you'd been assigned to. During the night, you didn't have enough time to finish dying your clothes, so you finished it off. You overhear two girls talking and, once you'd finished dying your clothes, you headed to them to talk. The girl in red looking at you.

"Oh hi there. I remember you, you were that were that guy who told me not to worry about that explosion thing yesterday. My name is Ruby, this is my older sister Yang", she said pointing to the larger girl with blonde hair.

"Nice to meet you Ruby, my name is Rudy, but call me" The Beast", And if you see someone called Blake Belladonna do not tell her about me. I'm her little brother", you replied and showed them a picture of Blake. The two girls nodded.

"So I noticed that your locker is pretty empty. Don't you have any weapons?",  Yang asked you. You nodded and reached behind your back and grabbed" King with no Master" spun it around and put it into scythe form. Yang was surprised and Ruby was gaping at you like some sort of crazy fangirl.

"My weapons are "King with no Master" and my semblance. You showed them "King with no Master" in both scythe form and in it's sniper from. The two girls were surprised at your abilities. Ruby wanted to see more.
"You'll have to wait until my initiation. Ozpin told me that I'll be viewed by all the students at the academy once you've completed yours", you explained to her. She was disappointed, but she couldn't wait to see your abilities.

Timeskip to when your initiation begins

You stood on the platform and cameras began floating around you, transmitting back to the academy. Every student was watching, even Blake.

"Today, we fallow the initiation of a very unique Huntsman in training. He calls himself" The Great White Beast". Let's see what he can do", Ozpin spoke  to everyone present and pressed a button which launched you into the forest. Everyone watched, except the Schnee who didn't seem to care about you one bit. You landed on the branch of a tree and jumped down to the ground. You looked about and heard something. Suddenly a loud sound echoed throughout the forest and a large Ursa appeared. You stood there not fearful at all. You calmly grabbed "King with no Master " in sniper mode  and shot it dead in it's heart.

"To easy" You muttered to yourself and headed on towards your objective. Upon arrival you noticed a couple of chess pieces. You'd seen the others take pieces, but that was when there were about two pieces each, one for each pair. You shook your head and grabbed the black knight piece. You heard rustling and saw a Chaos rex heading right for you. The students watching were panicked you'd be ripped apart. You stood your ground and activated your samblance " Great white Beast". and roared before charging at the Grimm.

Both of you collided , you clawed at its side then attacked its head. It managed to shake you off. You tried to bite its back but was stopped by its bone armor. It then bit your leg, you roared in pain. You then kicked it off then you bit its neck and snapped its neck with a loud snap of its neck.

*Start at 49 till 55*

You then dropped its limp body and roared in victory. You turned back and shook yourself off and made your way back to where you'd be picked up and brought back to the academy. When you arrived in the hall you were greated by cheers and claps from the students. Ozpin beckoned you up and you handed him the chess piece. He nodded.

"Child, you effortlessly dispatched Grimm within seconds. And returned with a Relic. Would you like to join a team, or be by yourself?", Ozpin asked you. You took a moment to consider it. Being on the same team as Blake would be good but you needed space from that arrogant Schnee.

"For the time being, I'd like to be by myself sir. With your promission, could I have a dorm next to Team RWBY's please?", you replied. Ozpin nodded.

"Would you be ok with announcing your name to the school?" He asked you. You thought about it, and nodded before turning to the students.

"My name is Rudy Belladonna. My Semblance is the ability to turn into a massive albino baryonyx. Be forewarned should you try to fight me, I will not hold back ", you announced to the students, who clapped and cheered. Blake was shocked her little brother was here already.
"Ok Rudy. We will make sure to set up the dorm to go with your prehistoric power. It will be finished quickly", Ozpin said and went off to get it done
When the assembly, you headed to your new dorm. You looked around and were surprised.

"Woah! Ozpin wasn't kidding.", you said to yourself. You looked at the bed and smiled. It was amazing.

You placed your suitcase on the lower bunk bed and began sorting out your  equipment. You placed your study books on a nearby desk for later and some free time books on a shelf nearby the bed. You looked at your uniform and began to make adjustments to hide your Faunus features. You locked the door, removed your combat clothes and tried on the trousers. They seemed to fit well, there was enough room to help hide your tail.

You heard a knocking on the door and opened it to find Blake there.

"Rudy, is it really you?", She asked with tears in her eyes.

"Yup, sis. It's me", you said before giving her a toothy smile showing her your missing fang and ragged scar. Then moving away from the door and letting your albino baryonyx tail out. Blake hugged you tightly. You hugged her back and kissed her cheek before you sat down on the chair next to your desk and Blake sat on the lower bunk bed.

"Miss me sis?" You asked her with a smile. She wiped tears from her eyes and nodded. "I missed you too Blake", you replied to her before putting your tail away.

"Rudy, what's with the cargo pants?", Blake asked with her bow twitching. You checked outside making sure no one was listening before replying.

"Helps cover up my tail. The same way that bow hides your ears", you replied. She laughed a little.
It goes well with your dorm. Mind you don't lose them", she teased before heading out towards her dorm for the night. You chuckle before you locked the door and changed into your pajamas.

You brushed your fangs and washed your face before you settled into your bed for the night. You have a lot of work ahead of you and you needed rest.
