Natsu Dragneel vs. Gildarts Clive

 is a battle fought between Mage of Fairy Tail, Natsu Dragneel, and S-Class Mage of the same guild, Gildarts Clive.

Prologue
After returning from Edolas, Makarov starts the Annual S-Class Mage Promotion Trial and announces Natsu as one of the eight participants. Natsu chooses Happy as his partner and the two join the other participants and their partners on the ship towards Tenrou Island. Makarov later explains the rules of the "Power and Luck" trial and Natsu and Happy race with their guild mates in order to be the first one to choose a path. Natsu and Happy arrive at the island to see that four of the eight paths have already been taken and blocked. Natsu decides to choose the E-Path, thinking that Erza is waiting in that path. Happy is confused with Natsu's choice but Natsu tells him that he just wants to defeat Erza.

As they walk through the path, Natsu begins to shout for Erza to come out. Happy is still skeptical that Erza is in that path but Natsu insists, saying that E Path is for Erza Path. Suddenly, the two see Gildarts walking out of the shadows. Happy loses hope, thinking that there journey is over but Natsu smiles at Gildarts, preparing to clash with Fairy Tail's Strongest S-Class Mage.
