Theseus Scamander

Theseus Scamander (born c. 1888) was an English wizard and Auror for the British Ministry of Magic. He was the son of Mrs Scamander and Mr Scamander and the older brother of Newton Scamander.

Theseus was regarded as a war hero after his involvement in the First World War, and was promoted to Head Auror during the early days of the global wizarding war, with Theseus greatly contributing to the effort against Gellert Grindelwald.

Educated at Hogwarts School of Witchcraft and Wizardry and Sorted into Hufflepuff House, Theseus attended the school from around 1899 to 1906. While there, he was implied to have been a popular and academically gifted student, to the point of having been referred to as a "schoolboy hero".

Theseus was frequently described as being "very powerful" and was noted to be "commanding". Given his participation in the First World War, and his description as a hero, he appeared also to be extremely brave, and was therefore quite respected among International Confederation of Wizards officials. Theseus is highly intelligent, as he was academically gifted in both the theoretical aspects of his lessons, as well as their practical applications. In stark contrast to his anti-social younger brother Newt Scamander, Theseus is rather confident and outgoing. Despite this bossy and prim reputation, Theseus is a well-meaning, hard-working, noble, and responsible man, in true Hufflepuff fashion not allowing his status as a war hero to make him arrogant or conceited, and seemingly attempting to act as a good role model to his younger brother Newt Scamander. Theseus loved Newt, and attempted to give him useful advice to keep Newt out of political trouble, and patiently put up with the bitterness with which Newt treated him, simply wanting the best for his brother. Theseus is also quite affectionate, with him notably hugging Newt (though the latter was initially uncomfortable with this)

While it is unknown what kind of relationship they might have had during their younger years, if any, Theseus and Leta would eventually get better acquainted at the Ministry of Magic, where he worked as the Head Auror, and she as the assistant to the Head of Magical Law Enforcement, Torquil Travers, resulting in the gradual burgeoning of a mutual love between them, and an engagement. Leta's death left Theseus absolutely devastated, and he readily agreed to free Albus Dumbledore of the Admonitors, so that the professor could more actively help in the war against Grindelwald.
