Ben 10: Cosmic Hero

Ben 10: Cosmic Hero is a reboot of the Ben 10 franchise created by Golden-Sans78.

Black Star Saga
It's been 10 years after Kid Buu was defeated and Goku retired from fighting. One day, however, an Android Dr. Gero created before his death busted into the Lookout and stole what he thought were the Dragon Balls so he could use them to revive Dr. Gero. He manages to get the wish, but as it turns out, those where the Black Star Dragon Balls. According to King Kai, those balls where created by a unknown Namekian as a prototype for the Dragon Balls, and while they are stronger, they scatter across the galaxy rather then Earth. If they aren't recollected in about a year, the evil spirits within them will be released from them.

Unfortunetly, Goku and Vegeta are told to stay on Earth, as with Dr. Gero loose again there's no telling what he may do. Goten and Trunks decide to be the ones to go out and find them. Joined by Android 18 and Krillin, they use an old ship Frieza once owned to travel to different planets in order to locate the Black Star Balls. However, not only will they face off against foes wanting to keep what they think is the original Dragon Ball, Frieza's brother Cooler has taken over his empire and aims to hunt down the Z-Fighters traveling through space.
