Let's see if i wrote it okay.

Please review :)

"Rebecca! You have to dodge!" Natsu shouted in vain.

However, she didn't move a muscle. Instead, she opened her mouth. The flames weren't flying towards anymore but were rather sucked in. Goliath grinded his teeth.

"Rei, what the hell are you doing." he mumbled.

Somewhere else, Romeo was nudging the motionless body of Rei.

"Man, that guy was weak." Romeo noted.

Back with the kids, Rebecca wiped her mouth and grinned.

"Now I have a fire in my belly." she grinned mockingly.

"How dare you?" Goliath boiled over with anger. "Flame soul."

His entire body turned to fire. He sped towards the timid girl.

"I shall burn you to a crisp!"

"Goliath you idiot." Magma shouted.

Before Goliath could react it was already too late. Rebecca already made a meal out of him. In a few seconds he was gone. Natsu and Lucy couldn't believe it.

"Did I really see that?" Lucy asked baffled.

"She ate him." Happy was also confused.

"Just as I suspected." Erza smiled.

She stuck her tongue out with disgust.

"Tastes horrible." she spat.

"Rebecca." Jake smiled.

"Are you okay?" she asked him.

"Yeah I'm okay." he sat up.

"Here." she said softly.

Her hand began to burn with a red flame.

"Don't. They will see."

"How did you expect to defeat Magma without magic?" she grinned.

He looked at his sister and couldn't help himself.

"Fine." he accepted.

He ate her flame. Natsu and Lucy ran to their side.

"Are you two okay." Lucy asked.

"What the hell are you?" Natsu confronted them.

he had a serious expression on his face.

"I could sense it. You just Dragon Slayer magic. And not only that. You used the element of fire. Who did you learn it from?" he asked.

"We the 4th Generation Dragon Slayers of Fairy Tail." they grinned.

"4th Generation?" Lucy asked.

"We learned Dragon Slayer Magic not from a Dragon but from a Dragon Slayer." she grinned.

"That's why we have a unique type of Dragon Slayer Magic." Jake added.

"I've had enough of this." Magma shouted.

"I wouldn't let you." Natsu got up but the siblings beat him to it.

"No, this time we'll protect you all! That's why we came here." she stood.

Overflowing with determination they take a deep breath, gathering magic.

"No way."

"ROAR OF THE RED FIRE DRAGON!" Rebecca screamed at the top of her lungs.

"ROAR OF THE BLUE FIRE DRAGON!" Jake copied her.

A tremendous amount of magic in form of a blue and red flame mix and hit Magma. However it doesn't faze him. As if they expected this, the siblings stood unmoved.

"And just when I thought I got you out of my way….Nashi and Luke Dragneel. The Fire Dragon siblings!" he looked down at them.

The siblings give him a very grim look. The attack served its purpose and allowed Natsu to aid Lucy.

"This time we'll stop you for sure, Magma." Luke yelled at the man.

"I'd like to see you try. You failed every time so far. What makes you believe you can win this time?" he mocked.

"Just a feeling." they grinned.
"Did he say Dragneel?" Happy was confused.

Natsu had question marks hover over his head.

"So you lied about your names?" Lucy asked.

"We didn't want to tell you because we thought at this point in time it would erase our existence. But we should talk about this later. Right now, we have to save the future." they got ready.

Well well well.

Did I do this right?
