Dota 2/Lion the Demon Witch

Lion is a ranged intelligence hero that is usually played as a support. He is known as one of the best heroes at crowd control with his Earth Spike and Hex, both of which are potent disables. He can also do massive burst damage with his Finger of Death ultimate. If he ever runs low on mana, he can easily steal it from his enemies. A very scary hero to go up against.

Earth Spike
Earth Spike makes a line of spikes shoot along the ground stunning and dealing damage to any enemy it hits. A very easy to land stun that can easily nail multiple enemies at a time. You can use it to initiate a potential gank or to stop an enemy's escape. It can also be used during teamfights to leave multiple enemy heroes vulnerable for a short while.
