Oh wow, Sephiroth breathing could just insta gib R, If you think an argument can be made for R with his hax then I will keep the match up the same or shuffle the rules a bit but if not then I have a back up match.
Strong Force would ignore dura, but unless R makes a giant hand the size of Sephiroth, he isn't bypassing that regen.
Strong force is pretty massive and according to Knox used it to flood the earth and said it could regres all of asia back to the stone age...whatever that means.If by the giant hand the size of Sephiroth you mean the gravity manipulation then yea, R should be able to make an island sized hand
EDIT:Never mind about the island sized gravity manipulation, I confused it with Park Mujin's.R's gravity manipulation works just by touching his opponent
Speed unequalized? R copies Seph's arsenal and uses them against him. Better yet, he can just go up to him and touch away all Seph's power with Greed. And if Seph is divine in any way, R can turn him into his Borrowed Power with a thought.
Also, the 4457000c speed feat that R scales to was done by an old and weakened Okhwang who R is massively faster than. Like seriously, R blizes so hard it's not even funny.
4-B R opens with his Borrowed Powers, using them to attack his opponent directly. Most notably, he can use the powers of Okhwang, who can use physics manip. If he's pushed into a corner, he can theoretically use Satan's 200 quintilion cloning due to having him as a Borrowed Power.
Greed can absorb type 3 concepts if it means anything. Just confirmed with Bambu. Also it's absorption of strength, and the soul too, not just power. I don't think hax like this can be resisted through being on a higher tier.
