Not necessarily. I mean, most likely when it comes to re-skins, they’ll all be buffed eventually, but I doubt they’d all get buffed at the same time. For example, while both Magnetos did get buffed at the same time, both Daredevils weren’t, with only DDHK getting buffed. While they may have had some differences in their kits, their animations were the same, like the classic and symbiote versions of Spider-Man. So if you see one version get buffed, you might not necessarily see the other get buffed right away, but they may very well get buffed eventually.
Both Magnetos were buffed together only because of the mutant September month.
