I mentioned it a few posts back. It seems they're playing the long game with Whis background, very uncharacteristic of Dragon Ball. They hid he was stronger than Beerus. After displaying the time reversal, when asked what he was the mysterious answer was, "A life form called Whis".Araki wrote:I'm not seeing a lot of talk about this bit, but i find it very interesting. I doubt Toyotaro would be allowed to come up with something related to Whis' origins on his own. And the way it's brought up here feels almost ...gratuitous? It's like they wanna hint at something, or just tease the readers. Maybe we'll actually learn more about Whis in the near future.Kuririn suggest playing shiritori: Whis goes with "jirujiru". Goku asks what that is and Whis says its a bird on his planet.
I remember the theories when BoG was about to come out. How Whis was actually a villain. Just throwing it out there, I still think it's really far-fetched.
It really feels like this was in the head of Mr.Toriyama, ever since 2013. Not everything, just the main ideas.
