A Lightning bolt was the weapon of choice for Zeus, the chief god of Greek Mythology. Zeus received his weapon from the Cyclops, after freeing them from the dark abyss of Tartarus. The bolt, due to its immense power, was vital to make the Greek gods able to defeat the Titans, their sworn enemies, in a war unlike any other: The Titanomachy.
