Thor

Thor comes from Old Norse Þórr, the name of the hammer-wielding god of thunder, lightning, storms, and strength in Norse mythology. The name derives from the Proto-Germanic thunaraz, meaning "thunder." Thor was one of the most widely worshipped gods in the Norse pantheon, beloved by farmers and warriors alike as a protector of mankind against chaos and giants.

Thor ranks #140 among America's most popular pet names, and it has been propelled by both ancient mythology and the Marvel Cinematic Universe into a name that carries unmistakable power. Naming a companion Thor is a statement of admiration — for strength, for protectiveness, for the thunderous presence of an animal who makes an impression. It suits large, powerful companions with a commanding presence, though there is also something wonderfully funny about a tiny animal wearing such an epic name.
