Here is my attempt at a RWBY Batman crossover let's see how it goes. My money is on crashing and burning but you never know right. This starts just before the begin of Volume two. Anyway time to get started, reviews and thoughts welcome.

It was night in the city of Vale as White Fang members ran across a rooftop. The five members looked around the rooftop in a panic.

"I think we lost them." One of the thugs said.

"You said they were across town and wouldn't be here." Another thug accused.

As the thugs talked they failed to notice several small balls roll between them. The small balls exploded into a cloud of smoke. The smoke caused them to cough and was so thick they couldn't see what was in front of them. Before they knew what was happening a shadow was moving through the smoke. Muffled screams and gun fire could be heard. In a panic one of the thugs ran out of the cloud of smoke. Turning he aimed his gun as the smoke started to clear. The smoke cleared revealing the groups attacker. A girl in a black and red outfit that appeared to be made out of some kind of thick cloth. A red belt was wrapped around her waist. On her chest was a black bat symbol with a red outline. She wore red wrist guards with three spikes for catching bladed weapons, and a pair of red gloves. A long black cape with red lining fluttered behind her. On her face was a cowl with white eyes and a pair of short ears on top.

"Stay back Batgirl!" The thug shouted point his gun with shaky hands.

A frown appeared on the girls face, and in the blink of an eye she was holding the thugs gun in the air. If the thug was not so preoccupied he have noticed a trail of red petals behind the girl. "It's Batwoman!" She shouted before punching him. The punch cracked the man's mask and knocked him out.

"You used your semblance to reach him if he saw that it could endanger your identity." Batman said stepping out of the shadows.

"Am I fired?" Batwoman asked sounding slightly depressed.

"No, but you still need to practice." He replied. "It's getting late you should call it a night."

She wanted to argue with him but she knew better. Nodding she used her cape to glide to a nearby ally. A black motorcycle with a red bat logo on the rims was waiting for her. Hopping on she sped into the night. On her way to Beacon she thought back to when she met Batman, and how she stopped being just Ruby Rose.

It was late and she was leaving her favorite store where coincidentally she would meet Ozpin a few weeks later. On her way out of the shop she noticed a commotion coming from an ally way. Going to check it out she found none other than the Batman. The mysterious guarding that had been protecting Vale for a little more than a year. What she saw matched the stories about him. He was taking on a group of six White Fang members and having little trouble. That was until one of the thugs shot a strange gas in his face. The effect was almost immediate as his punches became wild. One of the thugs hit him over the head with a pipe causing him to go to the ground. Seeing he was in trouble Ruby jumped into action.

Using her speed she slammed into one of the thugs, and activated her scythe. She fired a round into a thug charging at her and used the recoil to kick another one, making him slam against the ally wall. After seeing this the other three rethought their options. Making the smart choice the three remain thugs decided to make a run for it. Seeing Batman still on the ground struggling to back on his feet she decided to let the thugs go.

"Are you okay?" Ruby asked kneel next to him.

Reaching down to his belt pressed a button. "I'll be fine they just used some kind of nerve agent." He said struggling to his feet. He only made it a few steps before collapsing back to the ground.

Ruby went up to him and put his arm around her shoulder. He was surprisingly heavy, but practicing with Crescent Rose had luckily made her exceptionally strong for her age. "You need help." She said.

"Car…" He managed to say as his breathing started to sound labored.

As he spoke a black tank like vehicle came rolling into the ally. The top of the vehicle opened as it came to a stop at the end of the ally. Taking a firm grip Ruby helped him to the car. Putting him in the cars passenger seat she jumped into the drivers. To her surprise the top of the car closed and it took off before she did anything. It surprised her even more when a voice sounded over the cars communication system.

"Miss please keep him from damaging anything." A dignified voice said.

"They used some kind of gas on him." Ruby said holding the Batman down as he started to thrash.

"There is an antidote waiting for him. Keep him from damaging any of the cars systems and the auto pilot will do the rest."

"Hey just calm down you're safe now." She said trying to calm the man down. His breathing was still labored but he stopped thrashing. "My names Ruby. Ruby Rose."

He looked at her and paused for a moment. "Mines Bruce." He finally said.

"Sir you are not in your right mind." The voice said sounding slightly panicked.

"I won't tell anyone." Ruby said.

She couldn't help but smile remembering the conversation he had with Alfred when they got to the cave and he had recovered. After he had a talk with elderly butler, Bruce offered her to be his partner and help him in his mission. Eagerly she took him up on the offer. After some training he start to let her patrol with him as the Batwoman, or as the media and thugs kept calling her Batgirl. She couldn't help but feel slightly mad that Bruce got away with being called Batman. He was only three years older than her, but no one ever called him Batboy.

Turning of the rode she drove into a sewer canal. She sped down the pipe, and as she drew closer to the end the back of the pipe opened. After she drove through it slid back in place like it had never moved. The cycle came to a stop in a large underground room. The room contained a large computer, training equipment, and two glass cases for storing her costume and a backup for Batman. Shortly after she started at Beacon, Bruce realized Ruby couldn't make a trip into the batcave every night. So he found an old train tunnel under Beacon and setup a work space for her. Ruby had not changed much from how it was setup. Save for adding a work-space for weapons and gadgets. She added a bit of red to the dark gray of the room, and dubbed it the garden. Ruby got off the cycle and started to remove her costume. As she walked away the floor rotated so the cycle pointed at the exit. When she finished changing she looked at the clock. It was already three at night. With a sigh Ruby made her way out of the cave and back to her dorm. After running into Professor Ozpin one night she had decided to use the window to get in and out of her dorm. She remembered the night she bumped into Ozpin.

It was late one night and she had just gotten back from patrol with Batman. On her way back to the dorm she had avoid several people. Once she was in the hall she was congratulating herself when a voice spoke behind her.

"Good evening miss Rose." Ozpin said.

"Busted." She whispered to herself. "Professor Ozpin I was…. Just going for a….. Walk, yeah a walk." Ruby said with a nervous chuckle at the end.

Ozpin gave her a small smile. "Miss Rose, something you should know is I know everything that happens at my school. That being said how my students spend their time outside of class is not my business. Unless it interferes with their studies."

"Well my studies are good. They are aren't they?" Ruby asked.

"Yes they are, but do be careful Miss Rose we wouldn't want your grades to slip. If that was to happen though I do believe our mutual friend would have something to say." Ozpin said walking off. "Do have a good night Miss Rose."

Since then he hadn't spoken about anything relating to her night time activities. It did make her feel slightly better that Ozpin knew. Entering her dorm she found her team was still fast asleep, so she silently climbed into her bed and quickly fell to sleep.
