1 The beginning of the strongest dragon of Fairy Tail

On a summer day the gate opened as the dragon slayors left for the future only one remembered what their life was like and that was Katsumi, the elemental dragon slayer able to use the elements ice, fire, air, light, ground and metal( he does get more).

"Igneel where are you?!" Natsu asked in a yell, he smelled a dragon around him and went and saw Katsumi "who are you? and why do you smell like dragon?"

"Hi Natsu, guess you had a memory wipe," Katsumi replied with a smile "we used to be such good friends but you forgot, well anyway my is Katsumi."

Time Skip (because I'm bored)

"Hey, where are you Igneel?" Natsu was yelling because Katsumi didn't tell him anything (also some information about their ages Natsu was 14 and Katsumi was 15) "Just shut up Natsu." Katsumi replied.

They were in a town known as Magnolia, as they walked through the town they got weird looks but all of a sudden a female with long violet hair while an old short grey haired man was next to her came up to them "Hello, why did you come here?" the old man asked and Katsumi replied with "I'm looking for jobs while this pink haired idiot next to me wants to look for the fire dragon Igneel since we are both dragon slayers."

The old man and the young girl looked very surprised at that answer so the old man asked "Um ok, well you seem very strong so do you want to join the magic guild Fairy Tail?" but Katsumi just nodded as he had heard it was a strong guild before hand.

"Ok me and Natsu will join as we get money as well Natsu will get to look for Igneel with the price of us helping do work for Fairy Tail," Katsumi said with a calm look "it's a win-win." A little bit later once they went to the guild and explained there magic(Katsumi only said about fire, ice and metal), after a person with spiky black hair started to argue with Natsu while Katsumi was thinking 'How the hell did it end up like this'

"Well as we have two new members who will make a good force for our guild, Let's Throw A Party!" Guild Master Makarov yells to the guild as they all start cheering. People started talking to Katsumi (not like he was listening) and Natsu so they knew a lot about the people in the guild.

Then Katsumi got called by the guild master saying he needed to talk to him about something important. "So, what is the real backstory behind you guys and what are your real powers?" Makarov asked because even if he is an old short grey haired man he was strong and sensed Katsumi's powers just didn't know all of them.

"So you know huh," Katsumi replied with a calm face but his hands were shaking because even if he had the strongest dragon slayer magic he was still only 15 so just answered truthy "we didn't lie about our names but I made fake backstories for us because I wanted Natsu to have a good life as he forgot why we were sent here, we were sent to kill Acnologia from the past I know that sounds odd to send children also I am known as the elemental dragon slayer but please don't tell the others."

After he spewed it all out, Makarov didn't know what to say but for some reason knew it was the truth and just showed a friendly face "Ok I won't tell anyone but I can't say anything for Laxus behind you." as soon as he replied with that Katsumi turned around to see no one there as Makarov laughed as he said no one was ever there and Katsumi sighs in relief.

A little while later, Katsumi had bought himself and Natsu an apartment even though Katsumi was 15 he still looked older so they got away with it.
