Sleipnir
Odin's eight-legged horse
In Norse mythology, Sleipnir (Old Norse: "slippy" or "the slipper") is the eight-legged horse who serves as Odin's trusted steed. He is the son of Svaðilfari and the god/jötunn Loki, the latter of whom is actually his mother, having given birth to Sleipnir in the form of a mare. Sleipnir is described as the best and fastest of all horses.
