Indeed, I was thinking about that video when I wrote my post.wolflonnie wrote:Did you know that, in Xenoverse 2, there is an unused voice clip for Rosé Kaioh-ken? https://www.youtube.com/watch?v=PiAAEPLhKCoSupremeKai25 wrote:The Kaio-ken is an OP ability, that much is clear, but Goku shouldn't be the only one to have it. It's a shame that the producers didn't have the balls to give Kaio-ken to Goku Black too. I mean, why shouldn't he have that ability? Zamasu was a North Kai, and he already had the Instant Transmission technique that was taught to Goku by the Yardrat species. I suppose that Super Saiyan Rosé Kaio-ken would have simply been unstoppable (Black didn't even need the Kaio-ken to stomp effortlessly his opponents), but at least they could have adressed the fact that Black hadn't unlocked Kaio-ken yet or something like that.
There is no logical reason why Black couldn't use Kaio-ken. Zamasu was a North Kai just like King Kai, the one who created that technique. In addition, Black already knew all of Goku's signature moves and transformations, so he should have known about the Kaio-ken too, especially since Goku himself had already learned and used that technique several times and Black inherited all of Goku's memories. The good guys clearly had plot armor so Black never even mentioned the Kaio-ken.
