MOBA Characters with friendly tethers (Friendship): Those are all that I know with a similar mechanic, and the three of them do almost the same with such mechanic: Grant movement speed, a percentage of your regenerations are granted to them and all of your abilities buff the tethered ally somehow.
 * Io, the Wisp: Grants both itself and the selected ally bonus movement speed, if Io regenerates health or mana the ally gets 150% of the restored values, enemies that cross the tether are slowed and the tethered ally is affected by Io's E (Grants bonus AS and Damage Reduction) and R (Global teleport).
 * Mina, the Tyrant: Passivebly bonds to an ally after a short duration, granting each bonus movement speed, and all of her abilities buff her tethered ally somehow.
 * Aphrodite, the Goddess of Beauty: Grants both herself and the selected ally bonus movement speed, 30% of her restored mana is granted to the ally, and all of her abilities buff her tethered ally somehow.
