[6] In Voltron: Legendary Defender, the Takashi Shirogane name is used, nicknamed "Shiro", with Sven making an appearance in the third season as an alternate universe version of him.
[8][9] Reconceived as Japanese and gay,[10][11][12] in contrast to Sven who was Norwegian and later married Princess Romelle, Shiro was originally intended to be a teenager but rewritten him to be 25 years old after his designs were finalised.
[15][16] Nicknamed Quiet (黙り, Danmari), Takashi Shirogane is the original second-in-command in Beast King GoLion, piloting the Blue Lion and wearing a black uniform.
In the final battle against the Galra, Sven sacrifices himself to ensure victory but ultimately survives unlike his GoLion counterparts to go onto the American original 3rd season of Voltron as an important recurring character.
Having become a famed gladiator in the Empire arena and receiving a robot arm, Shiro pilots the Black Lion of Voltron until the defeat of Zarkon in the second season, and he is apparently killed.
In the third season, Shiro is seen escaping the captivity of the Galra Empire, returning to the Voltron force and resuming his status as the Black Paladin after Keith chooses to become a full-fledged member of the Blade of Marmora.
He was then placed on "administrative leave" until he was approached by Colonel Hawkins to join a team of outcasts to search for the legendary robot Voltron on the distant planet Arus.
This brain defect caused him to fall under the influence of Queen Merla and Haggar, under which he betrayed his friends and Arus by stealing files from the Castle of Lions' control room.
However, the character's romantic relationships with Adam, who was only mentioned in flashback scenes and killed off-screen, and Curtis, his co-worker and eventual husband, were criticized for not being fleshed out enough and being poor LGBT representation.
