This is chain scaling. Not an independent feat Ben has made as what Reiner and the Marvel/DC policy page says. And the bigger the chain, the less it requires the characters involved in the outer parts of the chain to scale to the full value of the guy who actually made the feat. I.e. while Feedback can be MFTL+ to the 2000's, the discrepancy that comes from relativity can nerf Kevin all the way down to FTL or even lower because they're not crossing the same or greater distances or lesser timeframes, nor are there statements that their speed is static
As such, what evidence is there that Kevin's combat speed when attacking Ben is on par with Feedback's travel speed?
Bruh, my whole point is that their speed scaling is "Kept up with Gwen" and "Kept up with Charmmaster". But neither of them have anything expanding as to why they would be MFTL+, it's circular scaling. And either way, it's still not a feat, just a chain scale.
His profile isn't distinguishing between his normal attire nor his plumber suit. And either way, Max reacting to a random beam from miles away is not evidence of an MFTL+ feat unless the beam itself was proven separately to be MFTL+ feat. At best, the feat is relativistic.
So Zs'Skayrr doesn't have feats beyond relativistic, just chain scaling. Which is my point.
They do not, they require chain scaling to Feedback to even get their rating which is similar to this chain in the marvel page
