He is the heir of the Leicester Alliance and the leader of the Golden Deer at Garreg Mach Monastery, alongside Edelgard von Hresvelg of the Black Eagles and Dimitri Alexandre Blaiddyd of the Blue Lions.

While Claude is known to be an outgoing and laid-back individual, he is also known to be a remarkable cunning and genius strategist with a strong motive to open the borders of Fódlan to other nations such as Almyra, a rivaling kingdom that has conflict with the Leicester Alliance.

It is later revealed that he's half-Almyrian, as he is actually Prince Khalid (カリード, Karīdo), the son of the King of Almyra and Queen Tiana, the daughter of Duke Oswald von Riegan.

He later enrolled at the age of 17 at the Officers Academy in Garreg Mach Monastery, operated by the Church of Seiros and Archbishop Rhea, serving as the house leader of the Golden Deer.

[9] Writers Rebecca Katherine Britt and Ps Berge believed that Claude had queercoded dialogue due to flirty scenes with male Byleth despite having non-romantic endings.
