Beerus scales in an era far beyond Black. Even with all the zenkai boosts, it tracks that he is superior to the fusion
Not really. Within the context of the vid, the Fusion is only moderately weaker than him. And not by much. It also has to be noted that Kaioken BVB was outright physically superior to UI Beerus-As in, Beerus
wasn't superior. All BVB really needed to win was time, as well, as Black was able to cash in on massive Zenkai's that made his standard SSJ able to fight a SSG Vegeta. That, combined with his hax, should spell victory for him. Especially when you realize that 1) BVB never used a higher order of Kaioken. (That we know of). Even if he was using the full X20 to exceed Beerus (which he likely wasn't), due to the immense energy control superiority their form has they SHOULD be capable of a higher multiplier. And that's not mentioning that Black, one of his two parts, only had access to the 10x (meaning he should as the Fusion be capable of much, much more). 2) BVB at multiple times in the fight could have taken Beerus out. When he caught Beerus and then demonstrated Baby's physical matter, the GoD had been totally injured and could've been possessed. Had he cashed in on Zenkai's more and not let Beerus get to him, he would've overpowered him. Had he been more intelligent with his transmutation, Beerus would've been dead. Had he utilized his Ki body double, he could've gained the distraction he wanted to use the Kaioken. On and so forth. BVB's arrogance is what does him in, because he keeps underestimating the Hakaioshin and giving out secretive information. (Such as the Telepathy moment, when he reveals his knowledge of the Life-Link, abusing the Time Ring in front of them, etc.) That is to say, at repeated interverals BVB had an easy wincon and choose the harder path. Which makes sense, because arrogance + incidental adoption of Saiyan traits + Manga Black is a petulant child compared to Anime Black, who always remains calm and collected. Hence why here Black whimpers in death, whereas in the Anime Black saw death as an intoxicating thrill as he began to slowly become more syncronized with his Saiyan Body.
Edit: Also, another thing is Giru suddenly no longer functioning. The reason why is never explained (outside of the obvious fact he got thrashed hours beforehand), but right when he gets close he just dies. The obvious implication at the end is y'know, obvious moral Karma biting BVB in the ass (as it's the 4th Star Ball), but the point remains: BVB had yet another decisive option that fails him. (While some would interpret it as Beerus having done it, the GoD is responding to what BVB talked about before, trying to game the fight via Life-Link. This is especially obvious when you check back and remember that Beerus isn't able to figure out mechanical communications, and that BVB had Giru focus on a totally different set of Dragon Balls from the one Beerus DID listen in on. The normal ones instead of Black Star over at the Lookout.) In general, Beerus also had a few plot armor moments. Like when he decided to just cauterize his injury when he had no idea BVB could exploit those. Or when he figured out the telepathic communication, (and that in itself is odd considering BVB could just use his "mechanical" communication with his infected like he did in GT Canon before he forgot and started using verbal communication). I'd even argue Hakai'ing the metal is one, but a light variation, since from what I remember RIldo straight up transmutes that whole thing, not just creates an outer layer. And the obvious big one is having Sealed Kibito Kai, (not that it would've mattered because, as stated in vid his IT relies on an energy signature that doesn't exist). Though it was foreshadowed, so it gets an obvious pass. There's also minor things like them basically immediately figuring out that BVB uses the Time Ring to simulate dodging, after like a few seconds of this, despite the fact they literally state it's completely indistinguishable.
How many Immortality does composite Goku has?
1, 2, 3, 4, (Wish), 7 (Cannot die as he is already dead, if you want to count his dead self), and 8 (comes from TokiToki's Blessing).
