New Champ Idea

What if they made a batlike champion

Q: Sonic Strike, send out a ranged skill shot W: Midnight Gale: A short ranged attack in a cone that will knock back enemies in a small area right next to him, but only slows targets not in knock back range E: Vampiric Bite: He bites an enemy champ and leeches some of their health. The amount in based on his level and his enemies health, the less health he gets back(either this or a taunt of some kind) R: Supersonic Shriek: His ult has 2 parts, the first is a cone that when activated fears and knocks back anyone in the cone. the second part is a very long but slender skill shot that when it hits something they are also knocked back, but given a slight movement speed buff. Passive: Dweller of the Dark: When in the fog of war, he gains extra tank stats and has a slightly increased movement speed, but the buffs disappear when he is in the light or can be seen by a ward
