Fairy Tail Wiki:Relación Seis/Reli Gear

Natsu Dragneel
Natsu is one of Happy's closest, if not his closest, friend. Natsu was the one who found Happy's egg and raised it with the help of Lisanna and was the one who gave him his name. Since Happy's birth, the two are usually inseparable, eating, sleeping and training together. Over the years, Happy had shown his loyalty to Natsu, oftentimes agreeing with his thoughts and ideas. Happy is also willing to risk his life to help Natsu and the same can be said for Natsu. Happy also deeply cares for Natsu as seen when he was brought to tears when he was forced to follow his orders and leave him to fight Lyon.

In Edolas, Happy was horrified when he learned the truth behind his "mission" which is to kill Natsu and was overcome by guilt. However, Natsu, despite knowing about the "mission", still thinks of Happy as his friend, trusting him and calling him his partner. This trust continued even after returning to Earth Land as Natsu picked Happy to be his partner for the S-Class Wizard Promotion Trial, despite Happy not being able to help him in a fight. Happy accepts the offer and promises to make him an S-Class Mage.

Lucy Heartfilia
Lucy and Happy are fellow guildmates and team members of Team Natsu. Happy plays pranks or teases Lucy most of the time, often calling her "heavy", much to Lucy's annoyance. He also teases her whenever she is with Loke, rolling his tongue while saying "he likes you". Happy, like the rest of his team, also has a habit of going to Lucy's apartment without her consent, a habit that Lucy had learned to get along with. Despite all this, Happy and Lucy are really close friends and care for each other deeply as seen when Happy was crying when he thought that Lucy was leaving the guild. The two can also be seen together during most of their missions, with Happy giving Lucy support and advise.

Erza Scarlet
Just like the majority of the Fairy Tail members, Happy respects Erza and acknowledges her and believes that her Magic is extremely powerful, even to the point of betting money on her to win a match against his partner, Natsu Dragneel. However, because of Erza's power, he fears her, as shown when Erza arrived at Galuna Island to bring back the members of Team Natsu after they stole an S-class mission from the guild's second floor. When Happy was looking for Lucy, and saw that Erza had come to the island, he instantly tried to flee but his efforts were in vain as Erza easily captured him and tied him up along side Lucy forcing them to help her find Natsu. Happy treasures his relationship with Erza, demonstrated when he helped the members of his team, and Juvia Lockser, and Jellal Fernandes.

Gray Fullbuster
As members of the same team, Gray and Happy are good friends, despite Happy being the partner of Natsu, Gray's biggest rival.

Happy, however doesn't take part in Natsu's rivality against Gray, acting like a mediator: he usually ingnores it in order to achieve an objective, says that both are very strong Mages, or even uses the rivality to "power up" them, mostly Natsu, that gets very angry when he sees that there's something that Gray can do that he can't.

Carla
Carla is Happy's love interest. Happy first met Carla at Master Bob's Palace during the first assembly of the alliance assigned to defeat the members of Oración Seis and immediately fell in love with the female cat as he even asked Lucy to give her a fish from him. Carla, however, ignored him despite Happy's attempts to impress her. This attitude continued even after Carla's joining of Fairy Tail and even worsened as she began to be hostile towards Happy, telling him to not hang around her. Carla's hostility is later revealed to have rooted from her and Happy being from another world, Edolas and with Happy not knowing anything about it.

The two later went to Edolas with Natsu and Wendy in order to save their guild mates and the townspeople of Magnolia and were subsequently returned to Extalia, their homeland where they were informed about the true nature of their mission. Though horrified, Happy stood up for him and Carla, telling their kinsmen, the Exceeds, that they are not their puppets and that they are Mages of Fairy Tail. Hearing Happy's words gave Carla some hope and even prompted her to call Happy by his name for the first time.

The two later returned to Earth Land with their friends and Carla began to be friendly towards Happy, encouraging him to not give up before trying while Natsu and Gajeel were forcing him to fight Pantherlily and even accepted his invitation to dance with him. Happy considers Carla as one of his friends and deeply cares for her as seen when he was on the verge of tears when she was injured while strolling with Wendy prior to the start of the Grand Magic Games.

Pantherlily
The two first met each other while members of two conflicting forces during Happy and his friend's rescue mission in Edolas and Happy was surprised to see the large Exceed as a member of the Royal Army. After the activation of the Reverse Anima which sent all the Magic to Earth Land, Pantherlily was sent as well and he subsequently joined Fairy Tail, befriending Happy and Carla. However, their friendship doesn't stop Happy from getting angry at Pantherlily when it concerns Carla as seen when Pantherlily accidentally bumped Carla's bum.

Lisanna Strauss
When Natsu discovered Happy's egg, Lisanna volunteered to help him raise it, showing Natsu the proper way to hatch the egg. She deeply cared for the egg as seen when she was crying when she thought that someone took it and was partially the reason behind Happy's name as she remarked that he was the "bluebird of happiness", prompting Natsu to call him "Happy". Happy, in turn, thinks of Lisanna as a mother figure and was deeply affected by her "death" as he was shown to cry tears of joy when he found her alive in Edolas. Lisanna, meanwhile, deeply missed him when she was sent to Edolas as seen when she tightly hugged him when they returned to Earth Land.

Lector & Frosch
& Lector and Frosch are Happy's new rivals in X791.

Due to Happy's childish and nonsense nature, he was an easy victim of the sadism and sarcasm of the Exceeds of the Twin Dragons of Sabertooth. Having not met these Exceed in Edolas, Happy was surprised when he first saw them, prompting Lector to call him an "idiot cat with an idiotic face", followed by Frosch's agreement. During the discussion that their owners were having, Lector didn't do anything but keep insulting Happy and showing off his knowledge about Dragon Slayers, again followed by Frosch's agreements and praises. Faced with so much humiliation and unable to fight back, Happy swore revenge to the Exceed duo, starting an intense rivality with them, that could be compared to the one betweem Natsu Dragneel and Sting Eucliffe & Rogue Cheney, their owners.

Plue
Plue and Happy have a friendly relationship and can be found together any time Plue has been summoned by Lucy.

Plue and Happy get along very well and this could be down to their similar personalities. They met when Lucy had summoned Plue for the first time to show Natsu and Happy how a Celestial Spirit Contract works and the latter commented that it was strange that Plue was the Canis minor but didn’t bark.

Happy and Plue were seen to trick Lucy into thinking that Plue could talk, showing a playful bond. They are also seen at times to dance together, reinforcing their shared lighthearted nature.

Millianna
Being a cat, easily Happy become a target of Milliana's obsession towards cats.

During the Tower of Heaven arc, Happy was kidnapped by Wally Buchanan during his fight against Natsu Dragneel, whom he believed that has killed. Knowing Milliana's devotion, Wally Buchanan brought Happy to her after the fight, making the girl extremely happy in the same instant.

Happy was then brought to the Tower of Heaven and stayed in Milliana's room, that was full of cats. When Happy talked, Milliana got more excited about the new pet, despite Happy's complete unawareness about the situation, only worried about Natsu.

When Natsu returned to fight back Wally, Happy helped him, nevertheless, Millianna kept protecting Happy, showing again her extreme devotion even in a real fight and while Happy simply ignores her.

Lucky
Lucky is Happy’s astranged father and the two had a brief but friendly relationship.

When Lucky and Happy first met it was, and is, unknown to Happy that Lucky was his father. Lucky shouted at Happy and Carla to get off his land, scaring them at first. However, Lucky showed some compassion when he invited them into his house to escape the Exceed Army, though he continued to shout everything at them. Lucky bossed Happy about considerably, even when taking care of him, making Happy somewhat irritated towards him. Despite this aggression, Happy was seen to take heed of Lucky’s words and seemed empowered and motivated by them It was clear that the two had similar traits as Marl pointed out Happy’s flying style, comparing it with her husband’s on the similarity.

Lucky’s clear love for Happy was demonstrated when Happy left to save the others. Here Lucky and his wife stood in tears as they watched their son fly away. It was also implied by Marl that Lucky shared her strong parental ideals and feelings

Marl
Marl is Happy’s astranged mother and she held strong maternal emotions for him, despite the shortness of their relationship.

Happy did not know that Marl was his mother as he called her “ma’am” when they first met. Marl did know this fact however and was very caring, kind and warm towards Happy and Carla when they were in her home; she even called Happy a “Knight” in an affectionate way. Marl’s maternal emotions were shown when she recalled the events of 100 years previously and when she spoke about parenthood and how nothing but that mattered, showing her strong feelings for her child. She stood alongside her husband when Happy flew to the Royal City and cried at his departure.
