Meliodas (Seven Deadly Sins) vs Natsu (Fairy Tail)

[Agent Z]

Demon vs Wizard. Who wins?

[Dark Soul # 7]

Natsu can blow up mountain-ish sized creatures, but Meliodas was able to tank that kind of attack a few power ups towards the middle of the series and then he kept getting stronger. He can also respond in kind and I don't think we've ever actually seen Natsu get hit by the same level of destructive output he himself can produce. So he'd be at a disadvantage in a slugfest.

Meliodas can also send all the fire attacks back at Natsu with Full Counter, and Natsu can't eat his own fire.

[Nik Hasta]

Yeah, Meliodas beats Natsu pretty handily by the end of his series.

I can't counter this argument.

What Dark Soul said, I agree with, and would add that Fairy Tail’s speed algorithm or lack thereof probably gives Meliodas a significant edge there, unless they’ve upgraded in 100 Year Quest.*

*Fairy Tail’s speed algorithm puts the main cast probably in high-end bullet time, low-end speedster territory, maybe hypersonic for the fastest. SDS from what I recall eclipsed that by the end of Season 1, definitely Season 2 with Galand and such.
