So, I have a Dragon Ball fan fiction that takes place in an AU where Kakarot is sent to Beerus's planet instead of Earth, and Whis trains him while Beerus sleeps. Right now, the events of the story are at Age 780, and two major events are that Cooler becomes friends with Kakarot, swearing loyalty to him to the point where he kills King Cold on Kakarot's order when the former tries to overthrow the latter. The second event hasn't happened yet, but the Oracle Fish has warned Kakarot that he will face an Evil Saiyan in five years, and achieves a new form, which is more akin to a combination of Super Saiyan God and Super Saiyan 4, not Super Saiyan Blue. The Evil Saiyan, named Peppa, will become a love interest to Kakarot, but I'm drawing a blank on ideas, so if anyone would be willing to help, I'd appreciate it. Here's the fan fiction link, Kakarot's Path to Divinity
