I don't think so you're up with 100 year quest.
Bro Beat Erza with Natsu Fire dragon slaying Mgic and Gray Ice devil slayer magic enchantation.
He soloed a whole guild.
One shotted Ishagar 4th (If I'm not wrong) strongest wizard.
One shotted Natsu.
Only S rank to live up the hype is Laxus.
He scales above them without DF.
Natsu Fire-lightening mode is literally Laxus Power up.
Laxus haven't eat anyone Magic yet. Yet so powerful.
I am upto date with 100YQ lol
And no, everything Laxus did in the arc is nothing compared to what DF Natsu is capable of.
- DF Natsu completely vap'd the body of FH Zeref
- DF Natsu's all out attack blew an island sized hole through dragon Aldoron's body, vap'd nerfed human Aldo
Neither of these feats were with Natsu eating anyone's power. Because otherwise, I would've included DF Natsu mid diffing Mercuphobia, but that's unfair because Natsu ate Ignia's fire to get powerup.
At best, Laxus scales to someone like Suzaku, after he got a poweup from Kirin. Which itself is me giving Laxus a lot of benefit of doubt, because Suzaku one shotted Erza (that Laxus had to go allout to defeat) and base Natsu. Natsu needed to use his scales (i.e DF durability) to tank Suzaku's attack power, and by his own admission would still get one shotted by Suzaku if not for his scales.
Normally, Laxus is stronger than Natsu. But not when he ups his stats to dragon force level, he destroys Laxus (or really any other FT member including Gildarts)
