Author's Note: Ok boys and girls this is my new FanFiction called 'Green Flames Burn The Brightest For A New Fire Lord' it is a Teen Titans and Avatar The Last Airbender story.

It is also a Beast Boy X Harem Fanfic, the Harem including Azula, Ty Lee and Mai and I might add Suki too and for those Aang X Katara as well as Tokka shippers sorry but there won't be much of them in this story.

Summary: Beast Boy finds himself lost in another world during a fight the Fire Nation find him and take him to princess Azula who intends for him to help her (meaning after a while Beast Boy won't be a hero anymore).

Disclaimer: I don't own Teen Titans or Avatar The Last Airbender sadly, although some of you are probably saying thankfully but anyway.

Enjoy!

Green Flames Burn The Brightest For A New Fire Lord Chapter One First Step In taking The Walls Of Ba Sing Sei And The Final Home Fight.

In a world where what once was one nation are now separated into four each according to the elements of fire, earth, water and air a beautiful young teenage girl stood looking over a what people call a barbaric and ruthless nation. Her name is Azula the princess of the fire nation and daughter of the fire lord, fire lord Ozai.

Her eyes showing a gleam of pride as she watched the armies of the Fire Nation all standing a little way below her on a beach, the armies of course standing in perfect square formations and at attention awaiting the princess' orders.

Azula smirked at the army, her two best friends Mai and Ty Lee at her side as she spoke "Loyal armies of the Fire Nation for one hundred years we have been at war with the four nations of earth, water and air, now the air nation lay dead in their graves their temples empty, however there is still one remaining. But that will not stop us today for today we strike a fatal blow to Ba- sing sei. Today we will penetrate their walls and take the buildings and other contents within said walls for the Fire Nation and in the name of the Fire Lord Ozai" She announced and the armies cheered.

She took a moment to bask in the attention she was getting then continued "I have gained the Dai Li's loyalty, all of you are to head to Ba Sing Sei and await my arrival."

"Yes Princess Azula" They said then boarded the warships to head to Ba Sing Sei.

In yet another world where super heroes and super villains exist a large T-shaped tower stood in the middle of a City called Jump City.

This tower belonged to four heroes. Them being a half man half robot male named Cyborg. A green, pointy eared, shapeshifting vegetarian named Beast Boy. A grey skinned demoness named Raven. An alien princess with red hair named Starfire and a human boy dressed like a traffic light named Robin.

The five called themselves the Teen Titans Jump City's resident protectors, who has lately begun to drift apart due to some differential issues namely Beast Boy and Cyborg's constant arguing over eating meat and tofu witch just aggravated an already aggravated Boy Wonder even more causing him to also yell. Raven soon joined in on the argument claiming that she couldn't read any of her books because of the noise by then Starfire also involved herself.

The crime alarm sounded interrupting the team from their group argument as Robin looked at the Titans Computer, only for his growing obsession to grow even more as Slade was the villain causing 'complications' in Jump City. Robin turned to the team and said "Slade's back, Titans Go".

Slade stood in his lair looking at his newest destructive machine. This machine is designed for the sole purpose to separate the Teen Titans by sending them to different dimensions.

Slade's attention was drawn off of his machine to the steel doors that just blew open. Robin came into view first "Slade! What are you planning?" The easily aggravated Boy Wonder asked in his usual obsessed voice that made Slade smirk beneath his mask "Oh, but Robin, that is exactly what you can't seem to figure out now isn't it? But, I'll humor you since you seem to have had a rough day. I've built a new machine. One that is similar to the croton detonator except it doesn't tear the fabric of time, it sends you into other dimensions".

Robin gritted his teeth "You're a madman Slade. A madman that needs to be stopped, Titan Go" He yelled as the charged at Slade. Slade smirked 'It's time, now who to pick first?" He asked himself as he looked at his options 'Hmm Beast Boy' He thought as he started the device and shot it at Beast Boy 'Farewell boy' He thought as Beast Boy disappeared.

Azula sat by her window in her room looking out at the horizon, when she heard a strange sound coming from behind her. Looking to where the sound came, Azula saw a strange looking green skinned teen with pointy ears. Azula immediately felt threatened, getting up she cautiously made her way to the intruder to look at him 'He doesn't look so threatening, then again his eyes are closed and he seems calm' She narrowed her eyes at him then picked him up and placed him in a chair and then used a scarf to tie his hands to the arm rests and waited for him to wake up.

"Where am I?" Beast Boy asked as he scanned the room then his eyes fell on a girl roughly around his age sleeping across from him "You're in my room, intruder" He heard the girl speak as she rubbed the sleep from her eyes.

Beast Boy's eyes went wide 'Wow, she's beautiful' He thought starring at the girl "Wow, I mean, where am I?" He asked hoping the girl didn't hear the first part or that she would ignore it.

Azula moved to go face to face with the intruder "My room, in the Fire Nation. Now, I'm going to ask you a few questions and you are going to answer them, understood?" She asked with venom in her voice. Beast Boy nodded and she continued "Who are you? Where are you from? Why are you hear? And what kind of bender are you".

Beast Boy felt scared and decided to rather answer the questions "I'm Beast Boy. I'm from Jump City. I don't know why I'm hear and I don't understand what you mean by bend." Azula looked at him then gritted her teeth "Fire, Earth, Water or Air. Witch element do you bend?" She asked getting angrier by the moment.

Beast Boy gulped "I don't bend anything. I'm a shapeshifter, I'm a hero!" He yelled out in desperation. Azula paused "A shapeshifter eh? We'll see about that. Guards, take this 'hero to the courtyard! I want to test him myself" She ordered and then two guards came and took Beast Boy away.

A few minutes later Beast Boy found himself in the courtyard with Azula standing across from him, a devious smirk on her face "Come on now hero. I'm sure you can take me" She said as she sent two sapphire balls through her feet in Beast Boy's direction.

Beast Boy ducked on instinct then turned into a Tiger and charged at the princess of the Fire Nation. Azula upon seeing the changeling turn into a tiger felt interested 'Interest, so the intruder wasn't lying about the shapeshifting part. I wonder what else he can do' She thought as she jumped out of the green tiger's way "Is that all you can turn into?" She asked as she sent two more fireballs at him. The tiger shook it's head and decided to show his full power turning into the Beast.

Azula's jaw dropped when she saw the creature in front of her, a slight hint of fear in her golden eyes. The Beast ran towards her and slammed her against a wall, pinning her there before turning back into Beast Boy "Did I win?" He asked and Azula could tell he was shocked. She nodded as the guards helped surrounded Beast Boy. She gave the order for them to stop and they did "Come with me" She said walking out of the courtyard.

Beast Boy nodded and followed the Fire Nation princess with a few questions on his mind "So, I'm guessing by all the guards surrounding this place that you must be important" Azula nodded "I am, I'm princess of the Fire Nation" She said as if it was the most obvious thing on the planet.

Beast Boy's eyes nearly fell out of his head "A princess, wow. You must be a real hit with boys, right?" He asked with a wide smile on his face. Azula looked at him and felt herself heat up at his smile 'He has a nice smile.' "Not really, I've only kissed one guy and he didn't even know who I was because people tend to run away in fear of me" She said simply. Beast Boy looked down taking in this information "It's a shame, you're beautiful" He muttered under his breath witch unfortunately Azula heard "Say that again" Beast Boy was shocked that she had heard that "I, I, I said you, you're beautiful" He stuttered hoping Azula wouldn't kill him right then and there.

Azula smiled, for the first time in a long while she actually smiled and hugged him, kissing his cheek. Beast Boy's eyes bugged out "Whoa, whoa, whoa, whoa slow down there. You can't just kiss me, I hardly know you!" He said to the Fire Nation princess, Azula smirked "Well then let's get to know each other, I'm Azula" She said then turned serious all of a sudden "Let's go, We're have places to be" She commanded as she lead Beast Boy to her ship, the one heading for Ba Sing Sei.
