In the anime and manga series Fairy Tail, Dragon Slayer Magic and the Dragon Slayers themselves are generally attributed with being some of the most powerful characters. The Lost Magic, over 400 years old, has shaped many Mages into overwhelmingly powerful individuals, able to perform feats that other characters simply could not. Most have achieved Dragon Force at one point or another, which is "the final, most powerful state a Dragon Slayer can attain; granting them power comparable to that which a real Dragon possesses: the power to utterly destroy everything."
While there are 3 generations of Slayers, each is unique and formidable in their own right. So, which Dragon Slayers reign supreme? Continue reading to find out.
Formerly known as Cobra from his time in the Dark Guild Oración Seis, Erik is a bit of an enigma. The full extent of his power is difficult to gauge considering most of his major fights occurred in earlier story arcs of the Fairy Tail series. However, what we did see of the 2nd generation Poison Dragon Slayer is that he was able to fight on relatively even ground with both Erza and Natsu. The effects of his poison can be deadly, and "his Magic allows him to hear the voices of others' hearts."
Some time after the Dark Guild is defeated, Erik joins Crime Sorcière with Jellal and his former guildmates in order to take Zeref down.
9 Rogue Cheney
One of Sabertooth's 5 strongest mages, Rogue is the Shadow Dragon Slayer. Raised and taught Dragon Slayer Magic by the dragon Skiadrum, Rogue also had a Dragon Lacrima implanted into his body, making him a 3rd generation Dragon Slayer. He is able to use Shadow Drive (which is like a mini Dragon Force), activate his Dragon Force at will, and can also combine his powers with guildmate and fellow Dragon Slayer Sting in order to perform Unison Raid: Holy Shadow Dragon's Flash Fang.
During the Alvarez Empire arc, Rogue is able to defeat the Historia of Bloodman, one of the Spriggan 12: "Bloodman, in his Third Seal, engages Rogue in close combat, matching him blow for blow...However, after much decisive battling between the two, the Dragon Slayer comes out on top."
8 Sting Eucliffe
Sting is Rogue's counterpart and the Guild Master of Sabertooth, the White Dragon Slayer. Similarly, he was raised by Weisslogia and implanted with Dragon Lacrima, so he is a 3rd generation Dragon Slayer as well. This powerful Dragon Slayer was able to seriously injure the previous guild master, Jiemma, when it appeared that he killed Sting's Exceed partner Lector: "In his blind rage, Sting viciously attacks Jiemma, blasting a massive hole through the latter's body."
After becoming allies and friends with the Fairy Tail guild, Sabertooth assists during the Alvarez Empire arc. Sting is able to defeat the immensely powerful Larcade, who was the third strongest member of the Spriggan 12.
7 Wendy Marvell
The youngest of the Dragon Slayers, Wendy has grown and improved her skills massively since her introduction into the series. She was raised and taught Sky Dragon Slayer Magic by Grandeeney 400 years ago, then sent to the year 777 in order to defeat the monstrous enemy Acnologia.
While she does not enjoy fighting, she is incredibly skilled for her age. Not only is she experienced in healing magic, but she is also an Enchanter: "which allow her to attach her Magic Power to someone or something (including herself) to boost their natural parameters...Wendy's aptitude for enchantments is exceptionally great, with her being able to cast enchantments on a level comparable to a High Enchanter’s." Not to mention, during the Alvarez Empire arc, she was able to enter Dragon Force at will. She is one tough cookie.
6 Gajeel Redfox
The former Phantom Lord bad boy, Gajeel is the Iron Dragon Slayer, raised and taught by Metallicana. According to his former guild, he held the rank of S-Class Mage. His Dragon Force is nothing to laugh at and his appearance in Iron Shadow Dragon Mode is truly menacing.
This hard ass has had some pretty iconic moments throughout the series, from beating Rogue during the Grand Magic Games Arc to Torafuzar during the Tartoras Arc and Bloodman during the Alvarez Empire Arc. Willing to die for his comrades, Gajeel is a Dragon Slayer to be feared by any enemy.
5 Laxus Dreyar
Talk about a redemption story! When the 2nd generation Lightning Dragon Slayer is first introduced, he is...well, a bit problematic. The S-Class Mage wages war against Fairy Tail, believing the members to be weak. After his defeat, Laxus is temporarily excommunicated from the guild.
During the Tenrou Island Arc, Laxus returns to help his guildmates defeat Hades, much to everyone's surprise. Ashamed of his past actions, his attitude regarding Fairy Tail shifted to one of pride and love. During the Grand Magic Games, Laxus fought alongside his guildmates, defeating all 5 of Raven Tail's members, including his own corrupted father. After also defeating Jura, one of the 10 Wizard Saints, "there were some rumblings in the Magic Council that Laxus should now be endorsed as a Wizard Saint, but after his boorish behavior was pointed out, those rumblings soon subsided."
4 God Serena
Formerly ranked first of the Ten Wizard Saints, God Serena was "the strongest Mage on the entire continent." He was known as Eight-Dragon God Serena due to his numerous Dragon Slaying Magic Lacrimas implanted into his body. Though all are not known, he has been seen using Lightning, Cavern, Purgatory, Sea King, and Gale Dragon Slaying Magics.
During the Alvarez Empire Arc, as he and other Spriggan 12 members made their way to Magnolia, he casually destroyed the country of Bosco. Then, when blocked by Ishgar foes, "God Serena made short, easy work of his former fellow Wizard Saints [and Jura Neekis], emerging from the battle unscathed."
3 Irene Belserion
While the extent of her Magic is relatively unknown, Irene Belserion, also known as the Scarlet Despair, was the creator of Dragon Slayer Magic. Able to transform into a dragon herself, she is regarded as the Queen of Dragons.
She was the strongest woman of the Spriggan 12, indebted to Zeref for changing her from dragon to human form, unable to do so herself. In her fight against Acnologia, she earns his praise and deems her a worthy challenge. "The two exchange compliments...Curious about her identity, Acnologia poses the question and the woman simply states that she is called "Irene", wishing that she and Acnologia can meet once more." The fact that she fought Acnologia on even footing and was not defeated is proof of her monumental capabilities.
2 Natsu Dragneel
The main protagonist of the Fairy Tail series, Natsu is the Fire Dragon Slayer, raised and taught by Igneel, the Fire Dragon King himself. Unbeknownst to him for the majority of the series, he is the younger brother of Zeref who died 400 years ago, revived by his brother as the demon E.N.D.
Usually exuberant and silly, Natsu has always cared deeply about his guildmates, feeling that they are his family. If someone hurts the people he loves, they will have to pay, as shown with Jellal, Zero, Hades, Future Rogue, etc. He is able to combine his Fire Dragon Slayer Magic with various others, able to use Lightning Fire, Black Fire, and Fire Dragon King Modes. When Natsu activates the Fire Dragon King Mode, gained from intense training with the power Igneel bestowed upon him, Natsu's "power increases to the point that he could take down a member of the Spriggan 12 with a single blow...[his] speed and power drastically increase to levels that allow him to fight toe-to-toe with beings as incredulously powerful as Zeref, and even completely incinerate forbidden, powerful Magic such as Ankhseram Black Magic."
Needless to say, Natsu is an indomitable force to be reckoned with.
The OG Dragon Slayer: enter, The Black Dragon! The Dragon King!
Acnologia was one of the greatest enemies throughout the Fairy Tail series. Able to freely change between his dragon and human bodies, he had a frightening amount of Magic power. A violent, war-loving, and altogether ruthless individual, Zeref stated that he had the power to rule the world but chose not to.
From destroying Tenrou Island (along with most of Fairy Tail's strongest Mages) to killing the Fire Dragon King Igneel and eliminating God Serena in just one move, Acnologia is pretty much unstoppable.
