Sveith

Sveith is the slash ship between Sven and Keith from the Voltron: Legendary Defender fandom.

Fanon
Some Sheith shippers like to ship them for the potential angst: Sven and Keith finding bittersweet comfort in each other from being away from their beloveds (Shiro for Keith, Akira for Sven.)

Trivia

 * When Keith (and the rest of Team Voltron) believed Sven to be their Shiro, Keith was the only one to lower his weapon.
