GatoAzul: If it flies on the top half with it's mouth closed (when it can't eat the fairyflies), it'll fly on the bottom half with it's mouth open, and the other way around, and then keep switching until you kill it. Hope this helps.
OK, READ THE (incert choice swear word here) COMMENTS BEFORE YOU COMMENT! I have seen (insert number higher that 5 million here) requests on how to beat the (insert same swear word here) baron, such as poopydude123- NO IT IS NOT IMPOSSIBLE! Im 2 worlds ahead of you and Im level 17! And the Mayor Badge, There is NO EXCUSE for that. The instructions say, and I quote "Defeat the mayor on the challenging or heroic difficulty setting." Gowd, you guys are really (*sigh* another swear word) me off!
still fish...
AND GREGOR IS THE MOST ANNOYING THING EVAR! Ok, first, he's a roach...Second, when he has that vitality thing that heals around 900, he sometimes attacks twice, so heals 1800, and I am getting REALLY MAD AT HIM!
castertroy - use moves that drain his focus. when he has no focus, he does MAJOR shadow damage to himself(so you could add more damage by lowering his shadow defence)
