Natsu Dragneel is the main protagonist of the series and a member of the Fairy Tail Guild. He is frequently partnered with fellow Fairy Tail members Happy, Lucy Heartfilia, Gray Fullbuster, and Erza Scarlet. He is commonly known to the public as a powerful mage called "The Salamander." But this title has started to fade as the series progresses. Natsu's most prominent features are his spiky rosy-colored hair and his signature scaly white scarf which was given to him by Igneel. Natsu has a scar on the right side of his neck. He has no separate eye color, his eyes instead being solely the color of his black pupils. Natsu is of regular height, and his body is toned but not noticeably muscular. His member's stamp is located at the top of his right arm, just below his shoulder. Natsu has a carefree and reckless nature and, despite his constant brawls with the other members of the guild, is a fiercely loyal and protective friend. He has a particularly close, and competitive relationship with fellow members; Gray Fullbuster and Erza Scarlet. With the former, he has had a constant rivalry from a young age and although they often denounce each other as not being friends, they regularly watch each others' back even when they are enraged with one another. He has had the same sort of relationship with Erza—the two both being scared of her since a young age—and they seemed to have a fairly good relationship in the past as, according to Erza, they used to shower together. He befriends people rather quickly too, considering Lucy a friend and willing to team up with her only after a few days of knowing her. Natsu's father had left him when he was young. Igneel, a dragon, found him in the forest and ended up taking care of him. He taught Natsu how to speak, and use magic. But one day Igneel disappeared on July 7, X777; Igneel left Natsu to fend for himself without so much as a goodbye or an explanation for his reasons for doing so. This made Natsu look forward to the next time that they would meet.

Revy (レヴィ), sometimes referred by her full name Rebecca (レヴェッカ), is the female protagonist of the series. She does most of the fighting for the Lagoon Company. Very little is revealed about her past, although portions can be pieced together through the series. Revy is a Chinese-American born and raised in Chinatown, Manhattan, near Mott Street, spending most of her youth as a thief and murderer. Flashbacks throughout the series reveal that Revy may have honed her skills with firearms by shooting at cans, and that her first murder may have involved shooting an unknown man while using a pillow. It is unknown whether the pillow was used to suppress the noise or to help avoid looking at her first victim. Revy is very competitive, easily bored, and extremely ill-tempered. Unlike Rock, she is undiplomatic, believing in the use of brute force and coercion to get her way. In contrast to this, she's revealed to be highly ticklish. Revy is a merciless and sadistic killer, without a conscience, who will kill anyone at the slightest provocation, even unarmed civilians (as seen in episode 6). Dutch once made reference to University of Texas shooter Charles Whitman in describing Revy after she slaughtered the crew of the Neo-Nazis' boat after a previous conversation with Rock brought up some unpleasant memories, resulting in an internal fit of rage - she even threatened Rock with death if he ever questions or tampers with her way of life. Of all the characters in the series, Revy uses the most foul language. She takes maniacal glee in killing anyone and everyone. She is also a heavy smoker and drinker. She has a changing but volatile attitude towards Rock; though she respects him later in the series, she is mostly hostile towards him. She shot Rock at point blank range, but he moved her gun at the last second, during a confrontation in episode 7, and in episode 1 emptied most of a magazine in his direction while arguing with Dutch about their hostage. However, she does have a tendency to save Rock from critical situations, and later on she admits to considering Rock as family to Balalaika. It is possible that she has an attraction to Rock, based on her reactions to Eda's teasing, which appear to be jealousy. According to CIA agents on Basilan Island, towards the end of episode 12, Revy is still notorious in the NYPD, particularly at the 27th Precinct. Since the 27th Precinct does not exist in real-life New York City, this throwaway reference may - or may not - indicate an odd connection to Dick Wolf's Law and Order franchise. This is further suggested in a later episode, when Revy specifically mentions the series. Revy is one of the deadliest fighters in the series, whose skill with firearms and ability to dodge bullets is almost superhuman and unparallelel. There are only a few other characters, such as Roberta and Ginji, that can hold their ground against her in combat. Her weapons of choice are a pair of modified Beretta 92FS's; which are made out of stainless steel and had their barrels extended from 4.9" to 5.9" each (the 5.9" is the combat MOD barrel) and also adapted for silencers. They are engraved with "9mm Sword Cutlass" on both sides, as well as the Jolly Roger of the infamous pirate Calico Jack (which is also inlaid into the ivory grips), and a manufacture inscription in Thai. Due to her ambidextrous marksmanship skills, she is nicknamed "Two Hand" by the denizens of Roanapur. However, Revy has been seen using a variety of other firearms. Constantly living on the edge of life, Revy has developed a rather bleak, almost nihilistic outlook on life, relying only on her own power, skills, and money. She does not believe in God or emotions. However, she seems to respect and trust her companions. (Source: Wikipedia)
