A new challenge had risen, this was a power so big the energy would have to be pure evil from the strongest demon star. A demon star was a ball of energy created by pure evil.
Vegeta and Goku both went to investigate along with Trunks and Gohan. A red and black mist with a pair of glowing red eyes Goku took no chances and powered up, the others did the same. As the most cleared a figure wearing a battle suit which was more black than the deepest of space. He said "I'm giving you one chance to leave, as if that would do anything because I'll kill you soon enough."
Goku was not about to cower in fear when the earth is at stake. "Your choice, leave or I'll kick your ass." Said Vegeta.
The man smiled and lunged for Trunks breaking his guard, Trunks had a kick to the stomach causing him to fly into the air and get caught by the scruff of his neck and impaled by a blade of pure energy. Vegeta grinded his teeth and lunged for his throat like a ravenous dog, even in his strongest form he got thrown down to the ground with his son. Vegeta dug his hand in to the ground, meanwhile Gohan was hit by a beam powered by a ball of energy which looked like a star. Goku's eyes began to twitch and as he shed a tear his hair turned purple and the whites of his eyes turned black along with his iris turning red. He cracked his knuckles and said "You made a big MISTAKE!"
