Still going with the idea that Zenos and the Scions will become uneasy allies and some kind of anti hero/rival that will return on occasion. He did mortally wound Y'shtola and I'd imagine she's not privvy to have such a psychopath in close range. Without an empire to rule, he'll be all about hunting sport. What if... he accompanies us during the 24 man raid? Hunting down the twelve if they somehow become manifested as super eikons? Or the Pandemonium raid? We know nothing of it yet unless day two of fanfest goes into more detail.

He could also get the Golbez treatment, though it would be a hard pill to swallow. Not sure how they'd pull that off. Going by his wiki he's been blood thirsty since he was a kid. Though guess if Vegeta gets a long redemption arc in another series anything can happen.
