Avatar Lee Sin (Ultimate Skin or Legendary Skin)
I do not know the order of these special effects, these are just ideas ;D
Q : Sonic Wave / Resonating Strike Earth : Lee Sin sends a rock of ancient power to the target location. Upon landing on an enemy unit, they are marked. Upon landing on the enemy unit, ground/earth particles fly out of the target enhancing the sickness of his kick.
Air: Lee Sin propels a gust of wind to the target location. While flying towards the target, a tailwind pushes him forward.
Fire: Lee Sin creates a blaze of fire and propels it forward. It has a fiery effect upon landing. Lee Sin creates flames that burst out of his target upon landing
Water: Lee Sin creates an orb of water and flows it forward. It has a splash effect upon landing, and upon Lee Sin's kick landing as well.
W : Safeguard / Iron Will Wind: Lee Sin rides a cloud of air to his target destination. His auto attacks for the duration of Iron Will has wind flying out of the target.
E: Tempest / Cripple
