Diane is one of the main characters from the Seven Deadly Sins anime and manga.

Diane is a member of the Seven Deadly Sins, the Serpent's Sin of Envy. She is also a member of the Giant Clan. 

About 700 years ago before the start of the story, Diane left her home of Megadozer and rescued King. For the next 500 years, they spent their lives together and fell in love with one another. Due to circumstances involving King however, he had to erase her memories and leave her. None the wiser, she returned back to her people to be trained under a fellow giantess Matrona. Later about 16 years before the start of the story, Diane met and fell in love in Meliodas, not realizing she was unintentionally misdirecting her true feelings. She then was involved in a plot by some vile Liones knights who intended to kill her and Matrona for glory. Although she survived the incident, Diane was made into a scapegoat for the massacre that had happened. Meliodas fortunately intervened at her trial and recruited her into the Sins. 

After the incident wherein the Sins were framed, Diane went into hiding in the Forest of White Dreams, forcing the resident Prankster Imps to aid her. When Meliodas and company came to the forest, she immediately rejoined the Sins.

In the XP4 fics, Diane debuted in the XP4 Heroes Coalition - Kick-Off!.

In the AWA fics, Diane, going by the full name of Diane Giant, is a student at the AWA Academy.

Appearance

As a giant, Diane is several times larger than an ordinary human being. She is a fair maiden, described as "lovely, beautiful" with purple eyes and medium length brown hair which is tied up into large twin tails. She has a well-endowed and curvaceous body. Similar to most of the other Seven Deadly Sins, her facial appearance is relatively childlike and has shown little change over the years. Diane's wanted poster depicts her with light colored hair. Her symbol, which is of the Serpent, is located on her left outer thigh.

When she was still a child, Diane wore ragged clothing until King made her a new set. Her clothes during the earlier part of the series resembles what King made for her, having sewn it herself by using leather derived from Dusk Bison skin. Her earlier attire consisted of a short-sleeved one-piece orange suit, boots with five crossed laces that extend almost up to her knees, and two finger-less gauntlets of a blue-grey leathery material covered in shiny steel stud - with the right gauntlet having been destroyed by Gilthunder during the fight in the Forest of White Dreams. She also wore a backpack previously used by Meliodas.

Ten years ago, Diane—as a Holy Knight—wore a full body orange armor with a unique helmet like the rest of her fellow Deadly Sins.

Diane's current clothes is made by Merlin and is almost the same style as her previous one, except for an inverted triangle cut on the chest, and the skirt. She is also wearing black underwear underneath the skirt.

Personality

Diane is a very friendly Giantess and is also very confident regarding her abilities, appearing to generally consider Holy Knights as weak. She cares very much about her captain and holds very strong feelings for Meliodas, often cuddling him and becoming very delighted from compliments. Her feelings are strong enough for her to overcome her fears for his sake. However, she is very quick to throw temper tantrums, and often does so upon becoming upset. Diane also gets angry and jealous when Meliodas does perverted things to other girls.

Due to her size, she cannot help Meliodas in any way other than fight for him. She has expressed her strong desire to be smaller, contrary to Elizabeth's desire to be strong. Despite Diane stating that she has no interest in humans, she still selflessly saves people who are in danger, like when the elderly man in Vaizel and Zeal were at risk, Diane risked her life to protect them.

Despite her brave and strong appearance, Diane is a somewhat emotionally fragile person, as shown by her hatred of loneliness. This was portrayed when she was a child and insisted that King stay by her side when she was sick instead of getting herbs to heal her, and when she waited in tears for him to return to her. Diane showed the same kind of feelings towards Elizabeth after she was kidnapped by Vivian. Whenever nervous or embarrassed, she covers her mouth with one of her pigtails and blushes.

Abilities

As a member of the Seven Deadly Sins, Diane is shown to be incredibly strong. She was able to punch the ground and use it to stop a horde of bugs from destroying a town. She has also shown to have great endurance as she was able to resist Gilthunder's lightning and even break free from it. As Matrona (normal human size), she possesses incredible physical strength and speed which she displayed during the fighting festival's preliminaries by defeating more than ten men quickly and with ease. Even as a young child, Diane demonstrates an extraordinary connection with nature, being able to create two Golems. Matrona, who trained her all her life, said that Diane had the potential to become the strongest warrior of the entire Giant Clan.

After passing the trial, her connection to the earth increased to where she can increase her power farther while dancing.mAccording to Melascula, her strength became comparable to Drole's. Drole himself believed that eventually she will become a greater ruler of the Giant Clan than himself because her love made her stronger than mere combat power.

Immense Strength: Since she's a giant, Diane is able to perform staggering feats of strength, able to clash with the likes of Meliodas in terms of strength and even break through barriers capable of withstanding meteors with a single punch. She can swing a war hammer with a weight of 998 kg (2200 Pounds).

Enhanced Speed: Using her strength, Diane is actually incredibly fast and agile, however due to her giant size this speed is reduced to nil, but when shrunken to human size her speed increases and is able to dodge rapid arrows shot by a foe of similar ability such as Gowther.

Immense Endurance: Due to being a giant, Diane is able to withstand several mortal blows, such as being pierced through the shoulder and thigh and still move fast enough to save citizens from collapsing buildings, and still retain consciousness even after losing blood and taking a further beating.

Enhanced Durability: Being a giant, few attacks are powerful enough to actually cause grievous harm to Diane, and she can shrug off all but the most powerful attacks from Holy Knights.
