Corrin is the customizable avatar character in Fire Emblem Fates. Their gender, physical appearance, voice, stat builds, and secondary class are customizable by the player before starting a new game. Corrin and their royal families carry the blood of dragons, being able to transform themselves or parts of their body to that of a dragon using their Dragonstone. They can also use Dragon Veins to alter the surrounding terrain in various ways, a power granted from the ancestral First Dragons.

Fire Emblem Fates is set on the territories of Hoshido and Nohr. Their royalty share a similar line of descent from the First Dragons, but they worship different deities: the Dawn Dragon and the Dusk Dragon, respectively. Corrin was born in Hoshido but kidnapped to Nohr at a young age, being isolated in the Northern Fortress during their childhood. Once they become of age and best their older brother, Xander, in a practice match, King Garon deems them worthy, providing them with the sword Ganglari to be used on the Hoshidan prisoners Kaze and Rinkah, among others. Corrin succeeds in defeating the prisoners but, out of compassion, refuses to kill them. Enraged, Garon has Xander kill the prisoners instead, but Corrin briefly clashes with Xander until Leo steps in to dispatch them (secretly leaving them alive) and convince Garon to lessen Corrin's punishment.

Garon sends Corrin to inspect a Hoshidan fortress above the Bottomless Canyon to pardon their crime. However, one of Garon's men, Hans, provokes the Hoshidans into battle and knocks Gunter, one of Corrin's companions, into the abyss of the canyon. Hoshidan soldiers later find and capture Corrin, who eventually recognizes them as the long-lost member of the Hoshidan royal family. Corrin meets their blood relatives and the songstress Azura, a former Nohrian Princess raised in Hoshido, in Hoshido's capital city. However, a hooded assassin attempts to kill Corrin, with Corrin's mother, Queen Mikoto, shielding them at the cost of her life. Out of distress, Corrin's dragon blood is awakened, transforming them into a Feral Dragon and causing them to rampage. Their rampage routs the hooded assassin as well as other mysterious soldiers in pursuit of Hoshido. Corrin is calmed down by Azura, who sings Lost in Thoughts All Alone to revert them to their human form. Afterwards, Corrin is given a dragonstone to control their dragon form at will, and claims the legendary Yato blade, which is said to belong to the one who will save the world. The Hoshidan and Nohrian royal families, now aware of Corrin's heritage, declare war on each other and eventually meet in battle for both conquest of their respective lands and custody of Corrin. Upon witnessing this great struggle, Corrin is forced to make a choice over who to side with.

This choice is dependant on what campaign the player takes, which all diverge at this point. In the Birthright campaign, Corrin sides with Hoshido and helps push the Nohr forces back, and is labeled a traitor in the process. In the Conquest campaign, Corrin sides with Nohr and helps push the Hoshido forces back, and is labeled a traitor in the process. In the Revelation campaign, Corrin refuses to take a side and instead forms an underground resistance movement in an effort to defeat both kingdoms and establish peace between them.

Corrin starts in the Nohr Prince/Nohr Princess class, a class-exclusive to them and their child, Kana. In this class, they can wield swords and Dragonstones. They can also transform parts of their body to attack when attacking using Dragon Fang skill. With a Master Seal, Corrin can promote to a Nohr Noble and gain the ability to wield tomes, or to a Hoshido Noble and gain the ability to use staves. In addition to this, Corrin has a wealth of other options - they can reclass into their secondary class with a Heart Seal, their spouse's base class with a Partner Seal, or an A+ supporting character's base class with a Friendship Seal. As they are able to Support almost nearly every playable character in the game, this gives them a myriad of possibilities for reclassing. Finally, they can use any of the various special reclassing items to access otherwise inaccessible classes, such as the Dread Fighter, Ballistician, or even character-specific classes like Marth's Lodestar class.

Since Fates, both the default male and female versions of Corrin have appeared in other Fire Emblem games. Both versions of Corrin can be summoned as illusory allies in Fire Emblem Echoes: Shadows of Valentia using the matching Smash amiibo, and both versions appear as units the player can recruit in the crossover game Fire Emblem Heroes. Female Corrin also appears prominently as a playable character in Fire Emblem Warriors, with the male version of Corrin available as well outside of story mode. Most recently, Fire Emblem Engage features female Corrin as one of the game's numerous Emblems, ethereal clones of protagonists from various other Fire Emblem games who dwell within special rings.

In MUGEN, Corrin is your typical sword fighter but also can transform into a Dragon! and uses some dragon parts for her moves. and is a great fighter.
