Also I'm guessing the general power levels for Fairy Tail is like this:
1) Zeref/Acnologia/Natsu (Fire Dragon King Mode)
2) Dragons
3) Gildarts/August/Natsu & Laxus (Dragon Force/Fairy Law)
4) Brandish/Spriggan 12/Erza/Natsu/Gray/Laxus
5) Makarov/Four Gods of Ishgar/Jura
6) Other 6 Wizard Saints/Gajeel
7) Other Dragon Slayers
8) Lucy
9) Other Mages
With a large gap of power between 1/2 and 3 and 3 to 4. Spriggan 12 was all made out to be all stronger than Makarov (with August being even stronger than the other 11), who is on par with the Four Gods of Ishgar.
