Javelin Thrower

One of the oldest weapons of all humanity, along with the wooden clubs, is the javelin. Short, light spears that can also be simple sharp sticks, Javelins differs from Blade on a Stick for many things: usually, while spears and lances are melee weapons associated to guards, soldiers, armies and-or cool-headed, calm individuals, javelins are different. They're weapons associated with speed, as its much lighter to carry than the spear.

Javelins are favored by horse riders who can use it instead of bows and arrows (javelins are much more economic to build and easier to use). Is also a very old weapon, so it's usually seen in the hands of wild, primitive looking cultures. If the work takes place in a sea setting then you'll probably see its water cousin, the harpoon.

Sometimes certain powerful characters won't be satisfied with mere shortspears and will show off by tossing very large spears around to fight. In Video Games, there'll often be the trick of javelins returning to the thrower or magically respawning in his or her hand.

Often associated with the Lightning element, in some cases they'll be coated in venoms.

See also Blade on a Stick, Prongs of Poseidon and Harpoon Gun for the technological version.
