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.)
