Natsu Dragneel vs. Gajeel Redfox

is a battle fought between Mage of Fairy Tail, Natsu Dragneel and S-Class Mage of Phantom Lord, Gajeel Redfox.

Prologue
Fairy Tail comes to the Phantom Lord Guild in Oak Town for a comeback for the damages done by Phantom Lord's Gajeel Redfox to the Fairy Tail Guild and to Shadow Gear. When Makarov, Fairy Tail's Master, leaves the battling to the Mages of Fairy Tail and heads towards the top floor to find Jose Porla, Phantom Lord's Master, Gajeel Redfox shows himself to the crowd.

Elfman of Fairy Tail battles Gajeel. However, Natsu, fueled by anger, insists he takes over their fight.

Battle
After using Elfman as a floor mat to launch himself at Gajeel, Natsu manages to blow him back with his flaming fist. The members of Phantom Lord express their shock at this, as they've never seen Gajeel pummeled before. Natsu introduces himself as Fairy Tail's Dragon Slayer. Gajeel gets up and attacks Natsu with Iron Dragon's Club. His arm becomes a much larger and much thicker pillar of iron and hits Natsu who takes it on. Still fueled by anger, Natsu, with his fists on fire, uses the iron pillar to toss Gajeel who is able to bounce back towards Natsu using the wooden pillars by the ceiling of the guild. When Gajeel comes in for a hit at Natsu, it is Natsu that manages to throw the punch at Gajeel.

Natsu's successful punch earned him a few compliments from his fellow guildmates, including Erza Scarlet. Elfman yells that he'll let Natsu have that man-on-man battle, but in return, he should beat him up good. Gajeel then gets up and tells Natsu that it didn't affect him at all, and Natsu replies that it didn't look like it. The Iron Dragon Slayer then comes in for a kick at Natsu using his iron leg and Natsu crashes to the floor. Gajeel taunts Natsu to bring it on, because the kick didn't affect him either. Natsu promptly gets up, complete with his flames, and confirms that he's right. Gajeel tells him that he's one hot and uncomfortable guy and Natsu tells him to shut up. With his iron arms, Gajeel yells that he'll crush Natsu and attacks him with his iron rods which Natsu blocks with his hands. Natsu, on fire, warns Gajeel to not get so ahead of himself and slightly crushes the end of the rod. Gajeel remarks that the rumors are true about his "pretty decent" power and takes back the rod. His hands steamed as it returned to normal.Gajeel asks him if that's all the Salamander has and Natsu replies that it was just a friendly greeting from one Dragon to another before their real fight. After a competitive glare, they both jump off the floor and go for a fist fight, Gajeel with his iron fists and Natsu with his flaming fists. When Gajeel manages to kick Natsu, Natsu comments that his kick was heavy.

When Gajeel comes in for another attack, Natsu sends him flying upwards. Sharp iron comes out of Gajeel's feet that lets him attach himself to the wooden pillars at the ceiling. Natsu jumps up and tries to punch Gajeel with his flaming hands. Gajeel blocks the attack with his iron arms but is hurled backwards anyways. Natsu, with a ferocious face, declares that he's all fired up. Gajeel attaches himself to the pillars once again and states that Natsu has a bit of destructive streak in him.

Suddenly, the Phantom Lord Guild rumbles and the members of it tremble in fear while the Mages of Fairy Tail look slightly smug as they acknowledge the shaking as Makarov's fury, or rather, The Giant's Wrath. They declare that as long as they have their Master, they cannot lose.

Moments later, a sudden fall of something on the ground distracts everyone's battles. When they look, it is Master Makarov, drained of all his powers. The members of Fairy Tail gather around their Master and indeed, they sense no magic power from him. Because of this, Phantom Lord's members' spirits are raised, as they still have their master, Gajeel and the Element 4 while Fairy Tail's Master has already been beaten. Phantom Lord is able to inflict damage to some Fairy Tail members, but Natsu warns them to not get cocky and continuously attacks. Cana Alberona is almost hit by some Phantom Lord's members' Triple Element Combination Attack but Macao took the blow for her.

Erza notices how Phantom Lord is gaining the upper hand and tells everyone to retreat and return to the guild. Everyone disagrees and insists they can still fight, but Erza tells them that without Makarov, they cannot defeat Jose. She tells them to retreat once more and that it's an order. Natsu, still in the middle of fighting, overhears Gajeel and Aria's conversation about capturing Lucy Heartfilia who is held at their headquarters. He calls out to Gajeel, who only says that they will finish their battle one day and then disappears.

Aftermath
The rest of Fairy Tail has already retreated with Makarov, but Natsu is still inside the Phantom Lord Guild. He grabs a random member of Phantom Lord and drags him out, accompanied by Happy. He interrogates the Phantom Lord Mage as he drags him around about Lucy's whereabouts, intending to save her. The Mage tells him he doesn't know and Natsu sets him on fire. Natsu warns him that if any more of his friends are hurt, he'll burn him to a crisp. In fear, the Mage tells him that the headquarters of Phantom Lord are up ahead and that she might be there.

Later, Lucy manages to trick Jose Porla in order to escape her prison. However, she is held in a sky prison and she might die if she jump off. She does, however, as she believes she heard Natsu's voice and that he'll save her. She cries out Natsu's name and indeed, Natsu comes just in time to catch her. Lucy believes that all the attacks were her fault and she apologizes, yet she wants to stay in Fairy Tail. Natsu tells her that of course she can stay and he and Happy takes her back to the guild.
