I kept thinking, Meliodas bypassing Zeldris' DK was a ludicrous feat...hence his confession "too damn strong" is validated... It's like Zeldris himself doesn't understand how he could be that strong. We know Zeldris' DK can only work against magic, so that basically gives away the nature of Meliodas' dark gravity-like restraint. Now if 200k couldn't touch Zeldris' DK (we know Ludo's STR was trash, spirit doesn't take much points, so his magic stat with Flash probably takes up more than 90% of his PL) how much more powerful must Meliodas be in magic? We now have full confirmation that Meliodas magic power itself was sealed all this while. When unleashed, that stuff challenges even convention reason (hence "can't exist in the human world any longer") & for its feat of power, it can destroy the Demon King's flesh. It never made sense to me that the next Demon King would have terrible magic. He's not Kenpachi the brute, Ichigo the newbie, or those typical shonen MC with limited movesets, he is a very very very very old & qualified Demon Prince who was unequivocally on his way to be crowned the new Demon God. He is a Madara type, a Juha Bach type more than anything. This is partially why I argue Meliodas is a BattleMage (all this while we've being deceived into thinking he's all physicality but something felt off about it to me). The Demon King himself (in spite of his build & appearance) isn't all about physicality (people assumed he was & the Supreme Deity would be all magic likewise but Nakaba isn't taking that route) as he by far has the best magic feat in NNT till date (of course bar Meliodas's destroyer magic which according to the DK's own testimony could fight his own Inversion). DK's magic is capable of creating a variety of magic (10C & their effects, other dark curses). His greatest feat bar his innate magic Inversion is probably creation magic--creating a being like Chandler to have very high magic power & also The Origin Demon (TOD) which would have substantially higher magic stat than a lone Chandler.
