The Snake Men are a fictional race of evil humanoid snakes in Mattel's Masters of the Universe franchise.

Released later in the original franchise's run, there was considerable retconning to work the Snake Men into the existing Masters of the Universe mythos.

In the distant past the Snake Men were a vast, ruthless army that conquered numerous worlds, and served an evil ruler named King Hiss. Hiss and the Snake Men tried to conquer Eternia, and created Snake Mountain as their base of operations. However, the Elders of Eternia proved too powerful for the Snake Men and used their magic to cast Hiss and his army into a limbo-like dimension. This caused the empire of the Snake Men to collapse, although a small number of them remained on Eternia. Eventually, Hiss is set free by Skeletor, who had made Snake Mountain his base.

Hiss and Skeletor form an uneasy alliance against He-Man, the greatest opposition to their mutual dreams of conquest. Skeletor's Snake Man minion, Kobra Khan, serves as his ambassador to King Hiss. Together the two villains are able to trap He-Man. They attempt to use their combined magic to pull the entire Snake Man army back into Eternia, but even their combined magical abilities united are only strong enough to return two snake soldiers: Tung Lashor and Rattlor, who had been on Etheria in the employ of the Horde. Realizing that they need more potent magic to resurrect the entire army, Hiss and Skeletor take He-Man's Power Sword, and attempt to use it to summon forth all the Snake Men. However, He-Man is able to free himself and recover his sword, foiling the return of the reptilian hordes.

A monarch is the person who leads a monarchy. This is a form of government in which a state or polity is ruled or controlled by an individual who typically inherits the throne by birth and rules for life or until abdication. Monarchs may be autocrats (absolute monarchy) or ceremonial heads of state who exercise little or no power or only reserve power, with actual authority vested in a parliament or other body (constitutional monarchy).

The word monarch is derived from the Greek μονάρχης (from μόνος, "one/singular," and ἄρχων, "leader/ruler/chief") through the Latin: monarcha (mono: "one" + arch "chief") which referred to a single, at least nominally, absolute ruler. In current usage the word monarchy generally refers to a traditional system of hereditary rule, as elective monarchies are rare in the modern period (though they do still exist in Vatican City, Andorra and Malaysia).

Most states have at most one monarch at any given time, although a regent may rule when the monarch is a minor, not present, or otherwise incapable of ruling. Two monarchs have ruled simultaneously in some countries, as in the ancient Greek city-state of Sparta or the joint sovereignty of spouses or relatives (e.g. William and Mary of Kingdom of England and Scotland, Peter and Ivan of Russia, Charles and Joanna of Castile, etc.).

Hiss may refer to: a noise made by angry or frustrated animals, such as cats, birds, snakes, etc.
