Natsu Dragneel vs. Mount Altana Guild

Natsu Dragneel vs. Mount Altana Guild is an anime-only fight fought between the Mage Natsu Dragneel and the four Mages of the Mount Altana Guild.

Prologue
After Natsu Dragneel and Happy set off for a training trip, following the war with Tartaros. During their travel, they stop at Mount Altana where Happy leaves to get fish. When he returns he finds out that his companion had eaten some poisonous mushrooms that doped him completely. He then tells Natsu that their fish was stolen by some bully guild, much to the latter's anger. Happy leads Natsu to the guild's camping site, where Natsu decides to go and retrieve their dinner. He appears before the four Mages, reclaiming their fish. Their leader states that every wildlife in Mount Altana belongs to their guild. Due to the mushrooms' effect, Natsu believes that the Mages have beaten up Happy and therefor readies his Magic to fight the four Mages.

Battle
Firstly, one of the Mages fires a Needle Hammer at Natsu, just to be blocked easily before Natus fired his Fire Dragon's Grip Strike, knocking the Mage out. The leader, overwhelmed by their opponent's powers, orders her comrade to smother his flames by water. The latter then uses Solid Script: Blizzard to freeze Natsu in an iceberg. Unexpectedly, Natsu breaks free easily, before battering his attacker. The remaining two recognize Natsu's identity, seconds before they are blasted by the latter's fearsome Fire Dragon's Roar. After that, the four Mages are seen struggling with each other to escape, much to Natsu and Happy's disgust. The Dragon Slayer, irked by their manners, finishes the outpowered Mages with his Fire Dragon's Wing Attack, demolishing the entire area with them.

Aftermath
After the fray, the over grilled fish collapses into ashes, as Natsu lies on the ground muttering in his unconscious, leaving Happy disappointed and burnt.
