No more "Passive Time Travel"? Hard disagree with these revisions.
Jokes aside, this is a much better foundation. I do have some reservations, though, such as the Demon Kings section not elaborating on much of anything or even justifying spreading the one ability there to others (who?) besides Mundus. Depending on who you apply this to, Creation may be a valid ability for this category, too.
If you do want to diverge Sparda descendent powers after a point, have an explanation in the page for it. Personally, I'm against it, though; that "Dante-only" section is mostly "enhanced XYZ" already present earlier, and since Vergil & Nero also surpassed Sparda then it makes sense for their XYZ to be enhanced to similar degrees as Dante's too. The "Dante-only" enhanced absorption bit even cites Vergil doing something similar for his Sin Devil Trigger, and Nero does essentially the same thing with his Devil Breakers! On the other hand, the Powernull/BFR bit is likely just Dante due to it being a technique he must use his exclusive Ebony & Ivory guns to channel, even if Vergil helped him do it using one of the guns and Sparda may have done something similar in the past.
Telepathy based on
figuring that a mad scientist emitting strong evil aura may want to do ambitious mad scientist things is a stretch, though, especially since that's literally the only showing cited.
Similarly,
that bit with the motorcycle was probably just some epic cinematic time effect instead of Telekinesis. Stuff like the Round Trip technique surely counts, but you should elaborate on that & probably qualify that they can control only their own weapons with Telekinesis.
I cosign most of this, but it might be a while before I have time to comb more thoroughly. The Sparda stuff aside from what I mentioned looks solid, but the esoteric stuff for other demons need some qualifiers (such as Subjective Reality needing one for being just a self-transformation thing even before the explanation like how Low-Godly via Possession does) or even citations such as the much-needed Weaknesses section lacking any (iirc the Vol 2 novel & show cover most of those bases). Still a big improvement over the prior page, though, you guys can iron things out from here.
