Early life
Dimitri is the crown prince of the Holy Kingdom of Faerghus. He was born in Imperial Year 1162 as the eldest son of King Lambert; his mother, the queen consort, perished in a plague that was later cured by Cornelia. He befriended Edelgard during her exile and she taught him how to dance. Dimitri gave her a dagger as a token of affection before she returned to the Adrestian Empire in 1174.

He was the only surviving royal of the Tragedy of Duscur in 1176. Dimitri's uncle and Lambert's elder brother, Grand Duke Rufus of Itha, ruled as regent in Dimitri's stead. During the Kingdom's retaliatory subjugation of Duscur, he saved and befriended Dedue who became his vassal. He fought his maiden battle two years later, where he distinguished himself as a commander in quelling a rebellion in western Faerghus.

Academy phase
In 1180, he enrolls as a student of the Officers Academy in Garreg Mach Monastery and serves as the house leader of the Blue Lions. Dimitri's childhood friends Sylvain, Ingrid, and Felix are among his classmates. His story changes depending on what class Byleth chooses to teach.

Blue Lions
Byleth chooses to instruct the Blue Lions house, helping Dimitri grow into a capable leader. During the night of the Academy Ball, the Blue Lions vow to reunite in five years for the Millennium Festival. Dimitri agrees to the reunion and hopes that everyone can make it.

{{Spoiler Text|However, hostile encounters with the Flame Emperor and Those Who Slither in the Dark drive Dimitri to become more ruthless. After the Ball, he confides to Byleth that Edelgard is his stepsister and that he gave her a dagger as a gift during their childhood. Dimitri suddenly hears voices and sees the Flame Emperor conversing with Thales. Believing that the Flame Emperor was responsible for the Tragedy of Duscur, he confronts them. The Flame Emperor denies involvement and vanishes, leaving behind a dagger which Dimitri r

{{S}}After Byleth merges with Sothis, Rhea instructs them to descend into the Holy Tomb and claim their power from the throne. The Flame Emperor interferes, seeking to raid the tomb of its Crest Stones, which leads to a skirmish. With most of the Emperor's forces dispatched, Dimitri unmasks their leader. To his shock and dismay, his suspicion that the Flame Emperor is Edelgard is confirmed. Outraged over her perceived involvement in his family's death, Dimitri snaps and slaughters her remaining forces. She is forced to retreat, but not before Dimitri vows to make Edelgard suffer for her crimes and kill her.

{{S}}Edelgard ascends the Adrestian Empire's throne, deposing Ionius IX and declaring war on the Church of Seiros. Dimitri fights beside Claude in the front lines to protect the Monastery from invasion. Although Edelgard and her vanguard are repelled, the invaders are reinforced by a larger army, forcing Rhea to enter the fray as a dragon. Byleth attempts to aid her, but Thales sends them plummeting into a ravine. Garreg Mach Monastery eventually falls into Imperial control, scattering the Knights of Seiros and personnel of the Officers Academy not affiliated with the Empire.

War phase Azure Moon

{{S}}After the fall of Garreg Mach Monastery and Byleth's disappearance, Dimitri is falsely accused of murdering Grand Duke Rufus, branded a traitor by Cornelia who declares Faerghus a vassal state of the Empire, and imprisoned for alleged regicide. He is able to escape imprisonment due to Dedue's apparent sacrifice but is presumed dead. At some point, he loses his right eye and lives a solitary life as a vagabond. Rumors of a sadistic warrior capable of slaying scores of soldiers begin to propagate throughout the Empire.

{{S}}In 1185, Byleth returns after a five year absence and finds Dimitri, now a shell of his former self, alone in the ruins of the Monastery surrounded by fresh corpses of Imperial soldiers. He mistakes them for a ghost but realizes that they are alive. A bandit gang raiding a nearby village spurs the two into combat. During the skirmish, they reunite with other members of the Blue Lions, fulfilling the promise they made as students. Determined to overthrow Cornelia and kill Edelgard, the Blue Lions reclaim the Monastery as their stronghold.

{{S}}With the Blue Lions reunited, Dimitri immediately plans on killing Edelgard by mobilizing his allies. The Monastery is suddenly attacked by Imperial forces in response to the Knights of Seiros returning to it. The Imperials are defeated and its leader Randolph is captured. Dimitri taunts Randolph, mocking his motivations as a general as well as concluding that they are both murderers. While Dimitri intends on slowly torturing the captive general, Byleth interferes and mercy kills Randolph.

{{S}}Acting on Byleth and Gilbert's counsel, Dimitri gathers more allies and support from the rebelling Kingdom nobles still loyal to him as the rightful King of Faerghus. In response to Rodrigue's pledge of support, they go to Ailell to link up with soldiers of House Fraldarius. However, they are intercepted by the forces of House Rowe led by Gwendal. After vanquishing the enemy, Rodrigue bestows Areadbhar to Dimitri and joins his crusade. Seeking to secure the Great Bridge of Myrddin, Dimitri faces off against the Empire. If Dedue's paralogue was completed during the Academy phase, he survives after helping Dimitri escape imprisonment. With the bridge under his control, Dimitri confronts Dedue and is relieved that he survived thanks to the aid of the same Duscur men he saved years prior. Dedue renews his pledge of loyalty to his liege lord but Dimitri makes him promise not to throw his life away again.

{{S}}Dimitri commands his forces to march into Adrestian territory, leading them to Gronder Field where the Blue Lions previously emerged victorious in their mock battle five years ago. For the first time since the war began, the three nations meet on the battlefield. The three-way battle is fierce and though Faerghus forces Edelgard to retreat, it is a Pyrrhic victory. Dimitri is outraged that she has escaped his grasp once more, but is fatigued from battle and urged by his allies to not pursue Edelgard due to Imperial reinforcements.

{{S}}Suddenly Fleche, a young maiden they encountered on the Great Bridge of Myrddin, appears on the battlefield and manages to wound Dimitri with her sword. Before she can land the final blow, Rodrigue shields Dimitri which allows Byleth to kill her. Rodrigue's sacrifice awakens Dimitri's conscience, and he realizes his lust for vengeance has not only consumed himself but affected others as well. Rodrigue absolves him of any responsibility for his death and tells Dimitri that he should live for his ideals rather than be shackled by ghosts of the past. With his dying breath, Rodrigue remarks that Dimitri resembles his late father Lambert. As a heavy downpour begins to fall, Byleth offers their hand to Dimitri and promises that they will continue to guide him. The other Blue Lions also vow to continue fighting alongside him.

{{S}}Afterwards, Dimitri apologizes to his allies for his foolishness. While not giving up on his quest to kill Edelgard, he declares his intent to liberate and reunite the Kingdom. Marching to Fhirdiad for the first time since his exile, Dimitri marshals his forces into the capital. Dimitri and his allies are able to penetrate Cornelia's fortifications and retake the city. When Dimitri confronts Cornelia, she reveals that his stepmother Patricia instigated the Tragedy of Duscur in order to be reunited with Edelgard. Dimitri is shocked by this claim but returns to the task at hand. With Cornelia ousted, Dimitri reluctantly walks out onto the castle balcony to find the people of Faerghus cheering his return. Dimitri takes his rightful place as King of Faerghus and continues his campaign against Edelgard.

{{S}}A messenger from the Leicester Alliance arrives in Faerghus with dire news that Volkhard is spearheading an Imperial invasion of Alliance territory. Dimitri and Byleth heed Claude's plea for assistance. They arrive in Derdriu with the assault already underway, but the Alliance has fortified the city and stalled the Empire's advance with skirmishes. The Kingdom's pincer attack turns the tide of battle and Volkhard's forces are defeated. Volkhard is mortally wounded, he evades Dimitri's questions concerning The Tragedy of Duscur and instead goads him to kill Edelgard before dying. Claude confesses that he gambled the Alliance's survival on Dimitri before he even retook Fhirdiad. He then hands Dimitri Failnaught and announces that he is abdicating as leader of the Alliance since the lords of the roundtable conference unanimously voted to accede into the Kingdom. After informing them of Rhea's imprisonment in Enbarr, Claude departs Fódlan on a personal mission.

{{S}}With the combined might of Faerghus and the former Alliance now at his disposal, Dimitri launches a proper invasion into the Empire. His army routes the garrison of Fort Merceus, slaying the Death Knight and securing a foothold in Imperial territory. A messenger from Margrave Gautier informs them that Faerghus has been pacified and will join forces with the Alliance army marching south. Dimitri briefly returns to Garreg Mach Monastery to interrogate a prisoner, who confesses that House Kleiman was a conspirator in the Tragedy of Duscur. Although disturbed by the revelation, he promptly returns to the front lines. As his forces approach Enbarr, Dimitri attempts to parley with Edelgard and learn her motivations for starting the war. She accepts on a whim and remembers her childhood in Faerghus after Dimitri returns her dagger, but the two are unable to compromise their world views.

{{S}}Dimitri besieges Enbarr and defeats a transformed Edelgard in battle. He attempts to reconcile with her, but she throws her dagger into his shoulder and he instinctively pierces her heart with Areadbhar, killing her. Forlorn, Dimitri is led away from the throne room by Byleth. In the aftermath, he is crowned the ruler of a united Fódlan. He spends the rest of his life reforming the continent; particularly alleviating poverty, improving foreign relations, and introducing a participatory form of government. With the assistance of Byleth, the new Archbishop of the Church of Seiros, the duo usher Fódlan into a new golden age. Template:SpoilerEnd

Silver Snow

{{S}}Dimitri is hiding in the Dukedom of Fraldarius after Dedue helped him escape execution in Fhirdiad. When the resistance army takes the Great Bridge of Myrddin, Gilbert is sent as an envoy to propose cooperation with Faerghus. Seteth allows them safe passage across the bridge, but declines to join them as he believes their advance towards Enbarr is reckless. Subsequently, news reaches Garreg Mach Monastery that Dimitri has died after his forces were decimated routing the Imperial Army at the Battle of Gronder Field. During that night, Byleth sees Dimitri. He laments the deaths of Rodrigue, Gilbert, and Dedue as well as his inability to restore the Kingdom or defeat the Empire. Before Dimitri is able to finish, Seteth interrupts and the prince vanishes. His ultimate fate is ambiguous, though many mourn Dimitri's death, Ferdinand believes that Byleth's encounter shows he is still alive.

Verdant Wind

{{S}}Dimitri is able to escape execution in Fhirdiad thanks to Dedue's help and raises an army in secret. After the Alliance army secures the Great Bridge of Myrddin, Judith declares that an army flying the banners of House Blaiddyd has marched through Alliance territory unopposed and is rushing towards Gronder Field. Rather than sending envoys to negotiate safe passage through the Great Bridge of Myrddin, the unknown army instead heads further east into Ordelia territory and frees the bridges from Imperial control. Dimitri leads his army into the three-way battle, attacking anyone in his path. Although the battle was fierce, the outnumbered Alliance army emerges victorious. He is last seen fighting until exhaustion in pursuit of Edelgard. The rearguard covering the Empire's retreat kills him after he collapses. Dedue survives the battle and vows to continue Dimitri's quest for vengeance.

Crimson Flower

{{S}}Dimitri ascends the throne of Faerghus and consolidates his power throughout the Kingdom by swearing fealty to the Church of Seiros. He gives asylum to Rhea and the Knights of Seiros in Fhirdiad, exiles Cornelia to prevent intrigue in the capital, and has Rodrigue escort her to Arianrhod and garrison the city with Fraldarius soldiers to ensure the loyalty of House Rowe. After the fall of the Leicester Alliance, the remnants of the Eastern Church flee to Fhirdiad. When Arianrhod is destroyed by javelins of light, Dimitri swears to avenge the fallen.

{{S}}As the Black Eagle Strike Force marches towards the Kingdom capital, Dimitri tells Rhea that his heir will continue the Blaiddyd bloodline and directs her to position the Knights of Seiros to flank Edelgard's forces before he intercepts them at the Tailtean Plains. The rain delays Rhea's advance, forcing the Kingdom to make first contact with the Empire. Hubert notes that Dimitri has grown shrewd, as his younger self would have simply charged the front lines rather than adopt a defensive formation in anticipation of Rhea's maneuver. Dimitri is distraught when some of his soldiers willingly turn themselves into demonic beasts, and chides Dedue for giving them Crest Stones without his consent. Dimitri is eventually defeated and slain by Edelgard. If Dedue is defeated before transforming into a demonic beast, Dimitri will instead die peacefully in his vassal's arms.{{S/end}}
