Chapter 1: New World No Memories

Shadow: I am Shadow the hedgehog and I am the CyberActors15 representative and I have been tasked by CA15 to give you some info about this story. First of all this story is based off of The Cross-Dimensional Adventures of Ben 10: Hero meets Phantom, written by Man of Cartoons but of course CA15's story will be different as Danny is the star character and not Ben and also Danny goes to the Avatar universe. Also this story should not be confused with the other one where Aang goes into Danny's world. Actually wait before I explain more about this story allow me to introduce our new CyberActors15 representative for the Avatar series, Katara from the Southern Water Tribe. *Cue applause sound*

Katara: Hi Shadow.

Dani: So CA15 finally chose a representative for the Avatar series? Finally!

Aang: I thought I was the representative.

Shadow: Actually first it was Sokka but CA15 dismissed the idea so then he put you in as he thought of a representative but then he decided to put the best character in the series and that was Katara.

Aang: But I'm the star.

Shadow: True but let's face it a lot of people love Katara. A star character is cool but a strong kick ass female secondary protagonist like Katara is even cooler.

Katara: Please don't take it personally Aang. CA15 is the boss when it comes to these things.

Shadow: And since she is the new rep that officially means that this story will have Katanny so in this story Aang and Katara never became a couple.

Aang: WHAT! When I find that halfa I'm going to…

Katara: This story will take place after Phantom Planet and after the Promise Trilogy but Zuko hasn't taken Azula out of mental care yet.

Dani: Also Danny will be the only good guy to appear from the Danny Phantom universe in the first few chapters but eventually I'll arrive and sadly I'll be the last person to arrive from the DP universe. This story is mostly about Danny in the Avatar world.

Katara: This is also a three way crossover between Avatar Last Airbender, Danny Phantom and American Dragon. So Jake will appear in this story as well.

Dani: Also CyberActors15 doesn't own Danny Phantom, Avatar Last Airbender, American Dragon, Shadow, or any Nickelodeon Characters that might appear in this or any Disney characters that might appear in this. But he does own the OCs.

Shadow: Now with all of that said it's time for a FANFICTION!

9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9- 0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0- 9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0-9-0

He grasped his side as he tried to get up.

He noticed that he was in serious pain so he tried to look around. He noticed he was in a small room that was made of earth. He saw a whole bunch of Green and Yellow Asian styled decorations. But there was also a bunch of blue decorations.

He once again tried to get up but he grunted in pain. It was then that he realised that his upper body was covered in bandages. He didn't remember getting into a situation that would require him to get such bad injuries. Actually he didn't remember anything. Not his name, nor his age or anything. He only knew general knowledge.

He then began to panic.

He then saw the door open and he saw a girl in strange blue clothing walk in.

"Oh you're finally awake, how are you feeling?" the girl asked.

He then calmed his breathing before he answered.

"I'm feeling a lot of pain." He said.

The girl looked at him sympathetically.

"Here allow me to take a look and your wounds and try to help you heal." She said.

He then stared at her with a confused expression.

"I'm a healer." The girl said before she knelt next to him. She then removed the bandages and he saw what used to be a deep gash and was now stitched up.

She then made a movement with her fingers and water floated out of the bowl and over his wound.

His eyes opened wide.

"Whoa how are you doing that?" He asked.

"Haven't you heard of waterbending?" she asked.

He just shook his head.

She then placed the water on the wound and the healing process began.

"Sadly I can't completely fix our wounds but I can hopefully get rid of some of the pain and help your body heal quicker." She said. "My name is Katara, what's yours."

He remained silent. "Danny… I think. That's the only word that comes up when I think of who I might be." Danny said.

"What?" Katara asked. "Don't you know your name?"

"I don't even know who I am, where I am, how old I am. I can't remember anything." Danny said.

"So I guess I can't ask you about your strange clothing or how you got these wounds?" Katara said. "Well I think that should decrease the pain for now."

Danny then stood up.

"Thanks Katara I actually feel better. Now if only I could remember something." Danny said.

"Maybe someone in the city might know you." Katara said. "I wouldn't mind helping you find someone who knows you."

Katara then lead Danny outside he was shocked to see the large city all around them that was made from stone and wood.

"Where are we?" Danny asked.

"This is Ba Sing Se the capital of the Earth Kingdom." Katara said.

Katara then lead Danny around and they started asking people if anyone knew who he was but everyone knew him as much as he knew himself.

It was a tad bit frustrating that no one knew Danny was and also irritating the way they stared at his strange clothing.

Eventually in two hours they still hadn't found any one who knew Danny.

The two of them then stopped in front of the Jasmine Dragon.

"Wow it's been two hours and we still haven't found anyone who knows you." Katara said.

"Jeez that kinda sucks as a freaking concept." Danny said. "And I still can't remember anything."

"How about we stop here at the Jasmine Dragon to get some tea before we continue looking?" Katara offered.

"Tea?" Danny asked. "Can't we go to a Nasty Burger and get some burgers and drinks?"

"Pardon?" Katara asked.

Danny was about to say something before he stopped. He then grabbed his head in pain.

"Danny… what happened?" Katara asked as he dropped to his knees while clutching his head.

"Sorry, I think I almost remembered something." Danny said. "It's kinda foggy but I saw this place and a whole bunch of teens around it."

"You look drained. Let's go inside get some tea and boost your strength." Katara said.

They went inside and once again more people stared at Danny's attire. He was seriously feeling like he was in the wrong place and if he didn't get out soon then something would go wrong.

Danny watched as Katara talked to the shop owner Iroh like they were old buddies. He had to admit Katara actually looked kinda hot and the way she was nice to him kinda made his heart flip.

"Whoa dude what about Sam?" a voice said deep in his mind.

"Forget Sam she's dating that new kid Chris Jones." Another voice said deep in his head.

Danny didn't seem to notice the voices but he did know they were there trying to bring his memories back.

Iroh then nodded happily and led Danny and Katara upstairs to the VIP section of the tea shop that was on the balcony that overlooked some of the city around them.

Katara and Danny sat down by the large table and when Katara ordered her tea Danny was just confused on all the names of the tea so he ordered the same thing Katara ordered.

"So how are you friends with the shop owner." Danny asked.

"He helped us during the war." Katara said as if that were enough of an answer. "And he's Fire Lord Zuko's uncle."

"Whoa what war?" Danny asked. "Better question you fought in a war?"

Katara then stared at him.

"Wow even with amnesia you should at least know the war." Katara said.

Danny then shook his head. "You said the same thing about your water magic power thing."

"It's not magic it's bending." Katara said. "But if you don't know I might as well remind you."

"Long ago the four nations lived together in peace and harmony..." Katara began.

"Whoa four nations?" Danny asked.

"Yeah, the Water Tribe, the Fire Nation, the Air Nomads… now Air Acolytes and the Earth Kingdom are all part of the four nations." Katara said. "Can I continue now?"

"Sure." Danny said.

"All of that changed when the Fire Nation attacked." Katara said.

"Attacked?" Danny asked. "Why?"

"The Fire Lord 100 years ago wanted the entire world to be one nation Fire." Katara said.

"Oh so they attacked?" Danny asked.

Katara then nodded.

"Only the Avatar, master of all four elements could stop them." Katara continued. "But when the world needed him the most he… vanished. A hundred years passed and my brother and I discovered the new Avatar, an Airbender named Aang."

"New Avatar?" Danny asked.

"Yeah every time the Avatar dies the next one is reborn in the next nation. It follows a cycle; Earth, Fire, Air and water." Katara said.

"Spring, Summer, Autumn and Winter." Danny said. "Cool."

"And although Aang's airbending skills were great he had a lot to learn before he was ready to save anyone. But I always believed that Aang would save the world." Katara said. "And you know what I was right."

"So there was a one hundred year war taking place… holy mother of god how could I forget that? Even with amnesia?" Danny asked.

"Okay so allow me to remind you about bending." Katara said.

She then explained the concept of bending hoping that it would help Danny regain his memories but instead it just further increased his confusion.

"Okay stop! My mind is blown and it feels like my brain just melted." Danny said. "I feel like you just explained how the Fenton Ghost portal separates your molecules and transported them piece by piece through 12 separate dimensions to get to the ghost zone all within 12 nanoseconds."

Once he said that he grabbed his head in pain. He then saw everything begin to blur together and fade into black.

He then collapsed on the floor as he saw Katara yelling for Iroh's help. Even blurred she still looked hot for the teen.

Danny then fell unconscious.

~00000~

In the Fire Nation Capital Fire Lord Zuko and Avatar Aang were unfortunately facing off against a pretty large rogue spirit from the ocean. They were facing a giant electric eel.

Not only could it fly and shoot burning hot blasts of water but it could also generate Lightning that made Azula's lightning, during Sozin's comet, look like a spark.

It sucked even more that the eel used lightning as its main attack.

Aang and Zuko had to be extra cautious when facing against the rogue spirit especially they knew what would happen if they failed to take it down.

The Fire Nation Capital would fall, the next avatar would be born and Azula would become Fire Lord. They shuddered at the idea.

Zuko and Aang continued to shoot blasts of Fire at the large Serpent but that wasn't doing much.

The Eel then roared before it shot a geyser of steaming water from its mouth right to Aang.

Before he could be hit someone jumped and pushed him out of the way and behind some cover.

He had jet black hair with green tips on the edge. He was in red fire nation armour that protected his torso, parts of his arms and parts of his leg with a white shirt underneath. He also had blue pants.

"You guys look like you could use a bit of help." He said.

"Are you sure you want to tackle on something like that?" Aang asked.

"Yeah I have my ways." He said. "Name's Jake, Jake Long."

Zuko then jumped and landed behind the cover.

"Jake Long?" Zuko asked. "There shouldn't be anyone left alive with that last name."

"So do you guys need help or should I continue walking." Jake asked.

Zuko and Aang then exchanged nervous glances.

"Do you know how to fight?" Aang asked.

"Are you kidding the Am Drag knows how to do more than just fight." Jake said with a smirk.

"Fine." Zuko said though he was confused why Jake called himself the Am Drag… actually he was confused by the name Jake. What kind of a name was that? For now he couldn't worry about that. He had a city to protect.

The three of them then ran out of the hiding spot and ran towards the Eel.

Aang and Zuko made sure to watch Jake to make sure he didn't end up ending himself and they were shocked by what they saw Jake do.

Fire consumed his feet before he flew into the air and curved around the Eel.

He then began blasting fire at the serpent.

"Aang is he flying?" Zuko asked.

"Good I'm not the only one seeing it." Aang said.

Zuko and Aang then got rid of the shock before they joined in the fight.

Aang then decided to try using earthbending to face the serpent while Zuko continued using firebending.

"We need more power to take this thing down." Aang said as he saw the eel slap Jake to the ground with its tail.

Jake then got up and wiped a bit of blood from his nose before he smirked.

"Alright." Jake said. "Guys get back!"

Aang and Zuko then jumped back not entirely sure what Jake was going to do.

"DRAGON UP!" Jake yelled.

A large tornado of fire then curved down from the sky and surrounded Jake's body. The Tornado then grew smaller until it was about half the size of the Palace. The flames then shaped into the form of a dragon.

The flames then vanished and there was a 25 foot dragon standing in the place that was formally occupied by Jake. The Dragon had a red scaled body and a yellow scaled belly.

It had five sharp black spikes that curved back. Then it had black and green mini spikes trailing down its back and ending on its tail that had black sharp spike projectiles that could be shot off at any time.

The Dragon was also in black armour that created three spikes on its arm and protected its torso.

"Yeah the Am Drag's is up in here!" Jake yelled in his dragon form. (AU: Yes I know Jake's look is different and yes I know I proper height isn't 25 Ft but hey you should see the other guy, Danny)

He then flew up to the Eel that was still larger than him and blew a giant blast of fire at the Eel.

Aang then shook out of his shock. "Okay then now that we're on equal ground let's get this spirit back to the ocean." He said as his eyes and Arrows began to glow.

Aang then began to float in an air bubble and he then called forth a lot of water and that formed a ring around him and he compressed it to make it small.

He only needed wind and water so he flew off to join the battle.

The poor eel now had to face the fury of a fully realised avatar and a human that could turn into a dragon at will.

It was quickly pushed back to the ocean and once it was there Jake tackled it while Aang used the ocean to pull it back.

The Spirit then decided it had had it with the human world so it dissolved back into the spirit world.

Jake and Aang then returned back to normal.

"Yeah the American Dragon and the Avatar, kickin' ass n' takin names." Jake said.

"So how did you turn into a dragon?" Aang asked.

Jake then smirked. "You might wanna sit down so I can explain my back story." Jake said.

~00000~

The next day Danny awoke in the spare room of the Jasmine Dragon. He saw Katara sleeping in a stool that was leaning on a wall.

"Whoa did anyone get the plates of the bus that hit me?" Danny said.

Katara then awoke.

"Whoa were you here the whole time?" Danny asked.

"Uh yeah sorry I kinda got worried." Katara said with a blush. "So how are you feeling?"

"Energised and a lot better than last night." Danny said.

"So, who's Sam and Tucker?" Katara asked.

Danny just stared at her blankly.

"You talk in your sleep. Do you remember anything?" Katara asked.

"Nothing. Except what happened yesterday." Danny said. "That was yesterday right?"

"Yes it was, don't worry." Katara said. "I was going to go visit Earth King Kuei today and since I can't just leave you I decided to ask you if you wanted to come with."

"Sure why not. Maybe on the way we might actually find someone who knows me." Danny said. "Let's just hope my brain doesn't malfunction again."

"Malfunction?" Katara asked.

"Stop working." Danny said.

In 10 minutes Danny and Katara left the Jade Dragon and walked towards the Palace.

Eventually Danny took notice of something as they walked. For the past two minutes they hadn't seen a lot of people around. There were just a bunch of people in cloaks that seemed to be watching them.

Alarm bells were ringing in his head like hell but Katara didn't really seem to notice the danger.

"Um Katara…" Danny started but he was cut off by a whole bunch of people that just appeared around them holding swords.

"Should we kill both of them or just the girl?" one of them asked.

"Kill them both." Another one, possibly a leader said.

The assassins then removed their cloaks to reveal men in white and green flexible armour.

They then went for the two of them and the fight began.

Katara had used waterbending to create her own sword so that she could block their blows while Danny had nothing to he went completely on instinct.

The assassins swung their blades but Danny was able to dodge each strike. He then curved around one of the assassins before he twisted his arm behind his back probably breaking it. Danny then jumped and kicked him into three other guys.

He then saw something coming from the side of his eye so he turned 90 degrees so that his back was to the assassin and then he brought his hands up and clasped them on the blade of a sword that was going to cut into his head. He then turned his hand thus snapping the sword before he held it with two figures. He then stabbed the blade into the assassin's leg before he grabbed the guy's arm before twisting it… thus breaking it… and he threw him into three more guys.

Danny then saw another Assassin coming towards him so he did a backflip over him and when he was in mid-air above the guy he grabbed him by the head before continuing his flip and took the guy with him. When he landed he slammed the guy into the floor.

"Wow guys tell me when the fight starts." Danny said with a chuckle.

Two assassins then ran towards him and he then smirked and ran towards them. He then slid between them and when he was in the middle he did a spinning kick thus knocking both assassins onto the floor.

He then saw a hook that was sitting casually on a basket waiting for him so he picked it up before he tossed it at one assassin. When it hooked he then pulled and the assassin before he delivered a punch to his head and the assassin then slid next to Danny after the punch.

Danny then picked up a Bo staff before he began swinging it rapidly.

An assassin then ran towards him and Danny then spun the staff a bit thus stunning him. He then began a series of quick rapid hits with the staff before he back flipped over the assassin that was charging behind him and thrust the staff forward and that hit the assassin into the one that was just beaten.

Danny then spun the staff around rapidly again before he pointed it out in one direction. His eyes showed laser focus and Determination. His eyes showed a warrior trapped within the wimpy body. He then dropped the staff.

"Everybody was Kung-Fu fighting, but Danny was fast as lightning in fact it was a little bit frightening but Danny fought with expert timing." Danny sang as he clapped.

Katara had seen how Danny had attacked as she had frozen the assassin that had come to her before she watched Danny take them all down in less than a minute. Then he started singing and dancing to a song she didn't know and she couldn't help but chuckle.

Danny then stopped and looked around before his jaw dropped.

"Whoa did I do this?" Danny asked.

"Yeah." Katara said. "It was amazing. I've never seen a fighting style like that. How did you do all that?"

"I don't know. It was instinct I guess." Danny said as he rubbed the back of his neck nervously.

"Wow so I can tell that you've been in your fair share of fights." Katara said before she gasped. "That's probably why you were injured yesterday, a serious fight and someone tried to kill you."

"Well that's a nice sentiment." Danny said sarcastically. "Who would want to kill me?"

"Well until we know who you really are we don't know." Katara said. "But I'll help you find out. But first we need to talk to the Earth King."

"Alright let's…" Danny said but he was interrupted when a small wisp of cold air escaped his mouth.

"What was that?" Katara asked.

Before Danny could answer a loud roar interrupted his thoughts.

He and Katara then turned around and saw a large blue skinned humanoid spirit behind them. The scary part was the fact that it had six arms and the other scary part was that it had 3 giant pairs of dual swords but the scariest thing was the fact that it had four faces, one on each side of the head. It had no shirt on, blood red eyes, a bald head, white marks caressing its body and was in what looked like ripped Fire Nation pants.

"Uh Danny I think I'll handle this one. I don't think giant spirits are what you can just use amazing skill on." Katara said as she pulled a lot of water out of thin air.

"Whoa you can't fight that thing by yourself." Danny said.

"I'm the world's greatest water bender." Katara said. "Of course I can."

Katara then dashed for the Spirit before she blasted it with a lot of water but that was futile because it breathed fire at the girl.

Katara then jumped out of the way of the flames. She then saw something disgusting as the spirit's head turned 90 degrees and glared at her but now it had light blue eyes. It then blew out a hurricane of wind that pushed Katara back.

It then charged at her with its sword and was going to cut her into pieces.

"Katara!" Danny yelled.

Then in a flash of light he was in front of her and he opened his hands out wide to take the blow. The swords then struck… but no one was hurt.

Katara then looked up and saw a green dome surrounding them.

She saw Danny had the same look of shock but she also noticed that his eyes were glowing green.

His shock then turned to the determination and the dome vanished as the halfa stared at the Giant.

"I won't let you touch her." Danny yelled before tangible green waves of energy shot out of his mouth and hit the spirit into a building.

Danny then stopped his attack as several brief images flashed through his mind.

He then smirked.

"I'm Going Ghost!" he yelled as he ran towards the spirit.

He then did a back flip and a silvery white ring appeared in the middle of his body in a vertical position. It then split and went side-ways turning his raven black hair snow white and his crystal blue eyes ghostly green. His white and red shirt, his blue jeans and his red sneakers all changed into a black flexible hazmat combat armour with a white DP symbol in the middle. There was also a white utility belt, silver metal gauntlets, white boots and a white cape on the outfit. (AU: If you can't imagine it, combine Batman, Superman and Danny Phantom). And when he was in mid-air he then flew towards the spirit before he began shooting ecto blasts at it.

The spirit tried to slice Danny with its large blades but Danny was able to evade the attacks.

"Hey big, blue and ugly give me a real challenge." Danny yelled.

The spirit then growled as it stood up. Its head then spun around again and now it had green eyes.

A sand storm then began to surround the spirit. It then thrust out its arm and sand flew at the Halfa and the waterbender.

Danny then flew to Katara before he picked her up bridal style… she bushed… and flew her over to another area.

"Danny how?" Katara asked.

"I don't know the full story, only one small memory came back, I'll explain what I know about myself after this." Danny said quickly.

"But…" Katara started.

"Do you wanna ask questions or do you wanna kick butt?" Danny asked with a smirk.

"I need water." Katara said.

Danny then swiped his hand over the air and a large wall of ice appeared out of thin air.

"You're a waterbender?" Katara asked.

Danny then shrugged.

Danny and Katara then sprung into action against the spirit.

Their combined abilities forced the spirit into submission before it decided it had had it with the human world so it melted back into the Spirit world.

Danny and Katara then jumped for joy before they hugged each other.

"We did it." They said in sync.

They then quickly let go of the hug as the both of them blushed.

Danny then turned back into his human form.

"So care to explain?" Katara asked.

"I'll explain what I know as we walk to the Earth King's palace." Danny said. "You still need to go visit him."

The two 15 year olds then walked towards the palace as Danny began explaining what he recalled thus far.

Dani: Wow.

Katara: I know right.

Shadow: That's what CA15 does.

Dani: I can't wait to see my look when I appear in this.

Katara: I wish CyberActors15 gave us new looks.

Shadow: No offence, but there's not much that he can do with your looks.

Katara: Offence already taken. I like my relationship with Danny.

Dani: OOOOHHH! Danny and Katara sitting in a tree K.I.S.S.I.N.G first comes love, then comes marriage, then comes… me in a baby carriage.

Katara: Very funny.

Shadow: But all true. Well in a different order, love, Dani, kissing then marriage.

Katara: Stupid teenage hormones.

Katara: Thank you.
