ok tell me if guildarts,erza, laxus can beat bluenote in one shot cause natsu dragneel can and he melt the whole grandmagicgames melt all that including people clother i think natsu is the strongest in fairy tale guild or 2nd

Can't be done. Guildarts can take him but not with one shot and he made Natus enviado to a lost in the S class trials. Erza put her all in her match against Asuma and barely won and he was declared must weaker then Bluenote. Laxus can hold his own against him. Like he did with Gura. But, he can't one shot him. And neither can Natus. Natus can't even one shot Grey!
