Natsu and Lucy have had so many heartwarming and heart-wrenching moments throughout Fairy Tail. Their relationship is one of the best in the series, so filled with love and care. They are always looking out for each other, sometimes even above their own health. It's the type of kinship, anyone would love to have.

The sheer amount of cute moments the two get is unsurpassed in the guild, and only Levy and Gajeel come close in terms of being a loving couple. That's exactly what they are to, even if they want to still deny that fact. While there were many to choose from, here are some of the most heartwarming moments the pair has had.

10 Natsu Invites Lucy Into Fairy Tail

This is one of the earliest events that happened in the series, but it's also one of the biggest in the entire story. Natus inviting Lucy to join Fiary Tail showed how lovable and caring he really was, even if he is a hot-headed goofball a lot of the time. The fact he did it after saving her from the false Salamander, Bora, only made it better.

By this point, Lucy didn't have the same feelings towards Natsu as she does later in the series, but it was a near-perfect way to introduce the two to one another. Lucy's dream of joining Fairy Tail coming in the most unlikely of fashions.

9 Team Natsu Forever

The original reason behind the creation of Team Natsu was due to Lucy's looks, since Natsu thought that she could infiltrate Everlude Mansion easily and finish an easy job.

That was just the surface reason, though. Right after the mission, Natsu had no desire to break up the team. He genuinely wanted to work with Lucy more even though at that time, she was far from the most skilled or talented mage in the guild. The fact he didn't care is incredibly sweet.

8 Lucy Jumps From The Sky Prison

This moment was the one where fans could truly see the bond these two hand, and that it was one that could easily go beyond just being friends.

Here, Lucy was kidnapped by the Phantom Lord as a means of both ransom and a goad Fairy Tail into a fight. Lucy manages to break free and jumps from the top of the sky prison, having faith that Natsu will be there to catch her as she calls his name. Natsu hears the call, leaping through the air to catch her in the nick of time. Now that's a trust fall!

7 Natsu Reassures Lucy That She's Part Of The Team, No Matter What

Spiraling out of her plunge, Lucy blamed herself for everything Phantom Lord was doing to Fairy Tail but at the same time, expressed a desire to stay in the guild. She loved Fairy Tail too much to leave it behind.

Natsu never blamed her and instead reaffirmed that she was part of the guild, swearing revenge on Phantom Lord for what they did. To top it all off, he carried her over his back while Lucy was in tears, realizing that she couldn't walk on her own.

6 Natsu Saves Lucy From Gajeel

Later on, Natsu comes to her aid yet again, this time from a pummeling at the hands of Gajeel. While Natsu usually has a level of anger whenever he sees one of his friends being endangered, there is a certain level of anger that comes when that villain is being violent towards Lucy.

He unleashed everything he had to keep Lucy safe, even if Gajeel was the superior fighter at the time. The sheer tenacity that Natsu had towards Lucy was pretty heartwarming, letting you see just how far their bond had come.

Despite having a badly wounded arm, Lucy's main focus was rushing towards a motion sickness having Natsu. The injuries didn't matter to her; all that mattered was getting to her friend.

Even as Angel knocked away the log that Natsu had been floating on, Lucy still clutched Natsu as tightly as she could, not caring that they were toppling over a waterfall together. Caring about someone above yourself is always going to be pure and heartwarming.

4 Natsu Threatens To Turn Everyone To Ash

During the Edolas arc, Lucy was imprisoned by the Royal Army. Couple that with the fact many of Natsu's friends were encased in Lacrima and it's not hard to imagine just how pissed off Natsu is.

It's easy to see how he reacted when he found out Lucy was going to be executed. As expected, Natsu threatened to burn everything and everyone to ash. While it is rather violent in nature, the fact that Natsu was willing to burn down a whole kingdom over Lucy is proof of just how much he cared about her.

3 Natsu Encourages Lucy After Her Loss To Flare

Lucy has never been overly confident in her abilities... at least those that aren't tied to sex appeal. On more than one occasion, she felt like she was the weak link, holding both her team and the guild back at points. This was no more evident than after her battle with Flare.

She was saddened more by the loss than she was about her injuries, more focused on the fact that Fairy Tail still had zero points. Naturally, Natsu was the first person there to pick her up, saying that the loss only made it more fun and that they'd finish on top in the end.

2 Lucy Catches Natsu's Scarf

This is the epitome of sweetness, and more than any other thing here, it shows how well Lucy knows Natsu. During his fight with Hades, Natsu's scarf flew off of him, nearly falling from the airship they were fighting on.

If not for Lucy, Natsu's signature scarf may very well have drifted off into the breeze, never to be seen again. Lucy dove after it, nearly falling from the platform herself. To care so much for a memento that isn't even yours is beyond heartwarming.

1 Lucy Hugs Natsu & Saves The World

This is the biggest and most heartwarming moment the pair has had. Natsu defeated Mercuphobia with the aide of the Dragon Force, but couldn't regain control of himself, stating his desire to burn the entire world down. If it weren't for Lucy's quick thinking, he may very well of done just that.

She rushed forward, wrapping him in her arms and holding him as tight as she could.  Very few would have risked that, especially with how Natsu was acting. Lucy didn't care, always putting him and his well being first.
