My Champion Idea
So Heimerdinger is a very renowned scientist and obviously has met other science-goers throughout Piltover. Well I think it's time to introduce one of Heimerdinger's comrades as a champ. (He would also be a yordle.) His name could be Zakon, which seems like a void creature's name but it's a word that's similar to the Polish word for "windup". So this guy specializes is Wind up toys, right, and for his Q he can send out a wind up toy that explodes on contact with an enemy. Another one of his abilities can be where he sends out a windup drill toy in a straight line and then it digs underground where it lands, concealed from enemy sight. On second cast of this ability, the toy underground will explode like a mine, doing some serious damage. His third ability can be where he summons a mini clockwork shield holder that stands in front of Zakon, protecting him until the toy is killed or runs out of time. His ultimate ability can be a very close range ability. If he uses it on an enemy, he stabs a giant wind up key into the enemy. Zakon is the able to control the enemy as if it were him for a few seconds. A great ult for setting up kills. However during the ultimate Zakon is very vulnerable since he is controlling the enemy champ.
