Chapter 1: Unsafe landing.

"...only the known is safe." Aro finished his speech as he turned towards the other side looking at the Cullen's and their supporters with his wicked grin.

Edward's eyes slightly widened in surprise when he felt Alice and Jasper who hastily made their way towards the Volturi while sparing a sorrowful glance towards Carlisle and family before walking towards the Italian coven.

But that didn't go quite well as the atmosphere started to turn dark and storm clouds forming a giant circle above them. Lightning and thunder followed the dramatic change.

"What in-" Marcus was cut off as light started to emit from a tear like state. The wolves and vampires moved back as the atmosphere started to emit electricity.

Before anyone could speak another word a humanoid figure came crashing into the snow, were it a human who was watching, they would only see the crater and debris it created but being superhuman, both species were able to clearly see what fell through that portal...or who fell.

It was a living male, in strange blue clothing. And he was now in the crater he created upon his fall, motionless. The crater emitted huge amount of heat and as a result, the snow surrounding it started to melt and seep into the crater and towards the boy, slowly. The Volturi and Cullens came to the edge cautiously, so did the others.

"He is alive...how is that possible?" Caius spoke shocked.

"Tha-" Carlisle began but was cut off by a monstrous roar that made everyone step back and Renesmee to burry herself into Jacob's back.

What in seven hell-" Alec was cut off by yet another roar but this was more of clear.

"Kakarot!" A giant figure came through the portal in a beeline before it closed and levitated in the air

"Kakarot Kakarot Kakarot Kakarot Kakarottttt!" The creature like humanoid roared chanting the name over and over while looking side to side.

Aro has never feared of death in the past as he knew he was the strongest among any earthly creatures but seeing this..this abomination made him cloud with fear.

The creature looked side to side menacingly but stopped when it fell on Renesmee who was sitting on Jacob, his face turned into a predatory grin as he observed the tiny creature causing Edward and Bella to form a protective barrier in front.

"Alec. Kill." Aro commanded the subordinate who sent his dark mist at the violent Saiyan who was still grazing at Renesmee. Alec's mist engulfed Broly who panicked a bit before the black mist engulfed him fully.

Although not in friendly terms with the Volturi, the Cullen's and the wolves mentally thanked them. Alec smirked.

"Hm. That was disappointing, I thou-" Alec's smirk was wiped off and a horror filled expression filled it. Every superhuman being standing there froze as they too horror stricken, watched the once arrogant vampire held in mid air by a giant glowing neon yellow being's hand, which was punctured through the vampire's chest.

The Volturi and Aro's witnesses jumped back just in time to see the Saiyan throwing Alec's body into the air and raising the very arm that held Alec vertically upwards and a huge ray of violent light which incinerated the vampire and destroyed the very dust into oblivion right in front of the audience around.

It didn't take soon for the monstrosity to start its rampage, tearing the ordinary vampires limb to limb. And to end it as well...

Now, the Volturi, Cullens, their allies and wolves stood on the same side of the crater while Broly stood on the other side over the ashes of the dead vampire grinning madly at the remaining.

They now knew what they were against. An unstoppable force. The speed it showcased a mere second ago was blinding for them, the punches that killed the fallen impacted the surrounding too.

"Jane, can you?" Marcus asked.

"Pain."

The word out of the vampire girl didn't do its usual thing but maddened the monster who slowly floated towards them.

"Jacob run! Protect Renesmee!" Bella commanded her friend to which the wolf ran but crashed it's head on to a rigid stone like body. Broly. The Saiyan was standing there with the same maniacal grin as he grabbed Renesmee by the head, which perfectly fit inside the giant's palm. There was resistance, but all were futile as everyone was blown away with a simple power up.

"Little bitch. No crying. No annoying. But I still hate it!" Broly said while levitating five hundred feet above the crowd as he held the struggling girl. The vampires tried to jump and attack but were swatted away like flies. Why Broly didn't kill everyone? For his sick amusement.

"Give back my daughter you bastard!" Bella roared as she tried again only to have the same result. She was blown down, sure to crash on the ground again but... She was caught and placed on the snow gently. Confused, Bella looked up to see the unconscious person in the crater standing in front of her, towering her while in his arm was a scared Renesmee.

Without another thought Bella jumped and ripped her daughter away from the demi-saiyan and into a tight hug.

"Thank-" Bella began but.

"Kakarot!"

Well that would make things interesting... Maybe more of a disaster... Gohan zeroed in on the giant while transforming into his second state. Broly and Gohan crashed fists in mid air, an auto of blue and green emitted from their colliding fists.

The End of chapter.
