The fact that Cosmic Garou can actually take on some pretty tough Dragon Ball characters in vs matches (especially with speed equalized) is pretty sick now that I think about it a bit more. Literally like 2 or 3 chapters ago he was peaking at Saiyan Saga level, now he's arguably reaching into Cell and Buu Saga in terms of just AP comparisons, not to mention the hax. I feel like a lot of people, not specifically here but in general, don't realize how busted he really is now.
His power mimicry is debatably on par with Novel Kars' "uNdErSTanD". Man casually started using gravity manipulation and portal creation within a few seconds (from his perspective of time) of seeing it. Hell, even Novel Kars can't just copy power itself iirc, but I might be wrong. This is on top of passive radiation that can cause blood loss, fainting, and rapid hair loss in seconds of exposure from just being within over a 10 meter range of someone (which causes very quick death if too close, in addition).
Right now, all Garou really needs is a good MFTL+ feat, and he's set.
Of course, all of this brings even more hype for how busted God is going to be. He should have the same powers he granted Garou, logically speaking, and then some. Like many people including myself have predicted, God is almost inevitably going to be a legit reality warper. Blast and especially Garou are already sort of reality warpers, just on a lower end scale than what people usually think of, and clearly God exists on a level far above them.
