Lightning is one of the 5 basic elements, when used on a enemy it paralyzing them, when used with water it's power is amplified due to water not be solid and lightning being able to run through it, earth is weak against lightning due to earth being a conductor for lightning allowing lightning to charge through earth and break it up, lightning is weak against wind because wind is a insulator to lightning, lightning and fire can be used as a combo if you fired a low-rank non-compacted fireball at the enemy and then quickly shoot a high-rank lightning jutsu along with, and if the opponent uses a water jutsu to stop the fire the lightning wil still travel and hit the water causing paralyses or maybe even death.
