July 7, X777

Cobra stood up from the cave floor and picked up the brown bag with rope strings. He had accomplished a lot these past four years training with his adoptive mother Chishi. He had absorbed Dragon Slayer magic like a sponge absorbs water. He did have problems with his Sound magic however until he got injured while on a trip to the nearby village. He had ended up losing the ability use his right eye. A scar now ran from just above his eyebrow to below his bottom eyelid. Losing the site in his right eye had given him better control of his sound magic as well as causing his ears to appear elfish.

He had grown quite a bit as well standing 5'9" tall. His outfit consisted of an elaborated whitish coat with purple inner lining and cuffs intricately decorated by silver-colored motifs, and many studs lined up the chest, the high collar and the sleeves, which have armbands seemingly made of metal around them above his elbows. Below it he wears a dark shirt, and he also sports a pair of crimson pants, composed seemingly of leather, held up by a studded belt, with more similar belts circling diagonally the upper parts of his legs, and simple brown shoes. (Same as in the manga during the Nirvana arc.)

Cubellios had grown a lot as well she was longer then Cobra was tall and when she grew her wings he could ride on her in the air. The two of them had exceptional teamwork with Cubellios's poison working as away for him to heal minor injuries as well as a power boost when fighting enemies.

Though Cubellios's poison remained deadly even if slow acting, Cobra was able to control poison making it non-lethal but very painful. Controlling his poison was the first thing that Chishi had taught him. As she had said he didn't want to end up having a friendly fight with an ally and end up causing their death a few hours after the poison entered their system. He could also make the poison act as a numbing agent or a drug that put someone to sleep for hours at a time if he wished.

Another good thing is that unlike when he started out he no longer had to enter Dragon Force to use his Dragon Slayer magic though if the need for it arose he could enter Dragon Force at will. He had also gained a power known as Poison Drive, which increased his speed and magic exponentially. The downside was that while in Poison Drive his poison was almost always lethal and very fast acting.

He looked around the Cave whose only occupants since Chishi had left very early that morning apparently were he and Cubellios. "Well Cubellios you ready to leave this place?" He asked his friend while shouldering the bag.

"Yes let us go see what awaits us on the horizon." Cubellios said ready to finally journey into the outside world after being mostly confined to the cave for the past four years.

Cobra couldn't help the smile as he patted her head before traveling out onto the mountain trail with her at his side. "I've heard the guild Fairy Tail is getting to be a pretty big deal. Why don't we go join them?" He asked glancing to his friend with his good eye, since she always stayed on his left side after he lost the use of his right eye.

Cubellios looked at her master and nodded before speaking what was on her mind. "In that case it would probably be best if I flew us there. At least part of the way with how far away Magnolia is." She hissed receiving a nod from Cobra.

"That's a good idea my friend. If you need to rest at any time head down to the ground and we'll rest for a bit before moving on." He stated as Cubellios nodded before making her wings grow out. He stepped up onto her back and then sat down in an Indian position as she flew south towards Magnolia.

It took the two of them a day in a half to finally make it to the forest outside Magnolia with Cubellios taking time to rest when she needed it. "Shall we go and join the guild now Cobra?" Cubellios asked while looking at her friend and master.

Cobra nodded and started walking into the town with his friend slithering along beside him. Cobra could hear that several people were afraid of Cubellios but he just ignored them as he made his way towards the guild. After an unimpeded journey do to people being afraid to get close to Cubellios they finally made it to the guild.

Cobra smirked as he could hear a commotion going on inside the guild. He was glad he had trained to dull noises to a manageable level otherwise his sensitive hearing would give him no end of pain. He pushed open the door and dodged a flying chair leg catching it just as it was going past his right ear. "Well this is certainly a lively atmosphere." He said drawing attention to himself as he dropped the chair leg and stepped further into the guild with Cubellios beside him.

Many of the guild members were startled to see the large snake while the younger generation was mostly curious about his scar though quite a few of them were afraid of Cubellios. "Is there something we could do for you young man?" A short little old man whom Cobra assumed was the master asked.

"I've come here to join this guild I've heard good things about it." Cobra replied with a toothy grin showing off his elongated canines. Before the master could answer a blonde with a lightning bolt scar over his right eye and wearing Sound Pod headphones showed up looking angry. Cobra could practically hear the outrage this teen felt towards him for wanting to join the guild.

"No way we don't need any more weak strays coming to our doorstep and wanting in. If you want to be part of this guild you have to prove that you have the power to back it up." The blonde stated glaring at Cobra. Cobra glared right back with his one good eye.

"Fine then but maybe we should take this some where that we won't destroy the guild or harm bystanders." Cobra stated stoically. He had decided that he already didn't like this guy. He reminded him far too much of some of the arrogant purebloods from his old world.

"Now Laxus there is no need for that. If this young man wants to join then he can." The old man tried to reason with the now named Laxus. However both teens kept glaring at each other neither willing to back down. "Very well then lets take this outback." The old man sighed. He looked at Cubellios curiously and Cobra was surprised that he couldn't tell what the man's thoughts were on her.

Laxus led Cobra and Cubellios out to the area behind the guild that was often used for spars and training purposes with the entirety of the guild following them. Laxus stood across Cobra in a relaxed position his posture and soul both telling Cobra that he thought he was no threat. Cobra glanced at Cubellios and nodded receiving a nod in return before she slithered to the side to watch.

"Lets see what you got punk. If you can't stand up to me you aren't getting in this guild." Laxus stated in the same arrogant tone he had used to challenge Cobra.

"I find it rather ironic that you know nothing of my abilities yet have already written me off as a weakling in your own mind. Is it that you're so confident in your own abilities that you see everyone as beneath you or merely just arrogance?" Cobra stated standing in a bored posture.

Cobra smirked to himself as he saw anger flash across Laxus's features before his body was covered in lightning and he charged at Cobra. Cobra jumped in the air covering his legs in crimson poison as he flipped in mid air to be upside down spinning and lashing out with his legs. "Dokuryū Rasengaku." He called out as he connected with Laxus knocking him out of the air.

In the crowd Natsu's eyes widened. "No way he's a dragon slayer to." He breathed drawing the attention of those around him.

Laxus stood up gripping his left arm and gritting his teeth while glaring at Cobra who looked back at him calmly still in his bored stance. Laxus was wondering Cobra had done to him, as his left arm was completely numb.

"Are you satisfied yet Laxus or do I need to show you what I can really do. The numbness you're feeling in your left arm is only a taste of my power. If I had wanted I could have completely paralyzed you if I had wanted but I held back. This time." Cobra stated staring intently at Laxus.

"You piece of shit don't you dare look down on me. I'm Laxus the Greatest mage in all of Fairy Tail." Laxus roared flaring his magical aura before causing a lightning bolt to come down seemingly on top of Cobra.

Everyone besides the master and Guildarts who was watching was surprised when the ground was scorched but Cobra was nowhere to be seen. Before he appeared behind Laxus causing the blond to look as if he had just seen a ghost as the Poison Dragon Slayer's killer intent washed over him.

"You lose Laxus. Dokuryū no Tekken." Cobra stated as his fist was covered in crimson poison before he punched Laxus square in the back sending him flying forward a few feet before he landed on the ground face first unconscious. "He should be out for at least a few hours. Some one skilled with healing should probably heal him to get rid of the poison even though I made sure it was non lethal." He said.

Almost everyone in the guild was shocked that someone had defeated Laxus so effortlessly. Makarov then approached Cobra and asked his name as well as where he would like the guild stamp and what color he would like it. He got it on his right shoulder in Crimson.

Makarov then took him up to his office and told him about the curse that was on Cubellios before telling him that he could break it. Wanting his friend to be as happy as she could possibly Cobra asked Makarov to do it.

AN: Yes I know I'm evil for leaving a cliffhanger but don't worry there won't be another time skip for a while yet. Also yes I know I have the timeline messed up pretty badly but as I said before this is AU so in this story Erza did make it to the guild before Natsu. Next chapter will have Cubellios changed into Kinana.
