Lightning

The Element of Lightning is numerically the first Element of the ten. Created by the particles from The Creator's mind to divide his ultimate speed into two halves - the other half was given to the Element of Light -, it is maintained by Lady Entegra. It's Elemental is the human called Energy.

Antithesis/Weakness
This Element is practically useless against Earth, where it can easily make the user lose control of the current, disabling it against the hardness of the material.

Uses
Lightning is primarily used for attacks that involve either extreme speed or the need to paralyze your opponent and, in extension, for laying traps or constructing prisons and/or cages (though almost every other Element can accomplish this).
