I do not own any part of avatar. I thought about what would happen if Aang had a twin sister and decided that it would make a great fic. Enjoy and please review. Possible Zutara and character death but I haven't decided yet so well cross bridge when it comes.

Chapter one: The Avatar.

The young airbender rolled her green eyes as everyone crowded around her younger twin brother. What made him so special? Rin asked herself before sighing and turning her back on Aang. There was nothing special about a 15-year old boy that could barely air bend. With everybody obsessing over the Avatar she would have to get her own diner…again.

Rin walked out the front door of the air temple she called home and took a running start before launching her blue glider off the edge and hooking on, her long dark brown hair flowing behind her. She was sure she could find a howlet somewhere. Unlike her brother Aang, Rin wasn't a vegetarian. Rin wasn't like the monks at all. She refused to get the traditional arrow tattoos and didn't really care what she had to do to survive.

She shook her head as she thought about how Aang would most likely be served diner on a silver platter. Ever since they found out that Aang was the next Avatar everything became all about him and she had been pushed aside. She wanted nothing more than to be an only child.

Aang squirmed through the monks that surrounded him. He frowned and looked around.

"Avatar Aang" a man addressed the young airbender. "What's wrong?" he asked.

Aang looked around again before turning to the monk "where is Rin?" he asked

"Who?" the man asked his brow furrowing.

"My sister" Aang almost yelled getting aggravated.

"oh." the monk mumbled obviously not knowing what he was talking about. "I haven't seen her"

As Rin flew on she watched the pull of the tide as the waves rose and fell. The ocean was beautiful. She flew over to a near cliff and landed on the edge. After looking around she found a high tree with a big nest on one of the higher branches. Rin jumped, using her bending to propel herself, up to the nest, but to her dismay it was empty. The dark haired girl sighed as her stomach growled. There had to be something for her to eat. She looked out to the horizon at the setting sun, dousing everything in an orange glow. The air bender jumped out of the tree and glided back to the air temple.

When Rin reached the air temple she found that nothing had changed. Aang was still the center of attention and everyone ignored the regular air nomad girl. She wished that for once she could at least get a glance thrown at her.

Rin walked past her little brother in silence. No one would pay any mind to her anyways. Everything seemed to be normal as she walked to the room her and Aang shared and hopped into her bed. Rin didn't notice Aang walk in a little while later and take his own bed. As Rin stared up at the ceiling sleep started to take her over.

It wasn't long before Rin was awoken from her dream, by what felt like a kiss on the cheek. Slowly she pushed herself up and rubbed her eyes. The young bender looked around the dark room to find that Aang and his glider were gone. Rin hopped out of bed and scooped up her own glider. The dark haired girl ran out of the room doing the best she could to make as little noise as possible. She followed Aang's bald head out to the stables where the flying bison were kept. Her brow furrowed as he slid into the building.

"Are you ready boy?" Rin herd the childish voice of her brother from inside.

"what is he doing?" Rin whispered to herself.

Rin had to jump out of the way as the huge door opened. Aang came out pulling a huge flying bison out with him. Rin ran up behind it and jumped on before Aang could take off.

"Come on Appa yip yip" Rin herd her brother sigh.

The bison's giant tail woshed through the air and slapped the ground pushing them up into the air. Rin ducked under the pouch that was on Appa's back as Aang looked at the air temple.

"goodbye" he whispered.

They flew for a while before Rin decided she was going to let her presence be known. Rin went to get up and asked Aang what he thought he was doing but the wind picked up and the grey clouds above them started to leak the rain they held. Rin let out a scream as Appa went down. Aang turned and held his glider up in defense only to realize it was his sister.

"Rin" "Aang" they both yelled as the bison crashed into there water beneath them. The last thing that Rin remembered was seeing a blue light
