Zero: The Empty
Just a little champion idea...
Sadness (Q) Zero sends sadness at a targeted enemy champion dealing 40/50/65/80/100(+.? AP) magic damage initially and slowing them for 2 seconds. The effected champions next basic attack or ability within 5 seconds will deal 80% reduced damage and deal 10/15/25/30 percent of the damage that it would have done back to the effected champion. While the enemy champion is saddened Zero gains 20/21/22/23/30 magic resist.
Anger (W) Zero sends out a skill shot of anger that can hit everything dealing 50/55/65/70/80(+.? AP) magic damage to champions and minions and 20/30/40/50/60(+.? AP) in magic damage. If an enemy champion is hit they lose 10/11/12/13/14 percent of their bonus AD and AP and also slowing them slowing them for 1 second.
Loneliness (E) Zero creates a cloud of loneliness in a targeted area dealing 15/17/19/25/35(+.? AP) magic damage per second spent in the cloud. When an enemy champion is in the cloud they lose all vision outside the cloud. If Zero is in the cloud with they cannot see him unless also in the cloud. When inside the cloud Zero gains 30 armor and magic resist
Mood Swing (R) Zero teleports to a selected area using all of his abilities at simultaneously in an area around him not putting them on cool down. All of Zeros abilities deal in extra (+.? AP) magic damage on top of the damage they already deal. Zero gains 200 movement speed for the next 2.5 seconds.
Lore Zero was a quiet kid. He looked a little bit awkward and he was made fun of for it. This made Zero angry, depressed, and he sat alone most of the time. One day Zero snapped accidentally killing five of the children who made fun of him. Zero then became afraid of himself and worried he would hurt the innocent, so Zero expelled all emotion from his body and mind. Zeros physical appearance changed drastically and some of his emotions were too strong to just disappear. The three strongest of his feelings Sadness, Anger, and Loneliness manifested into the physical world as snake like creatures that hovered and followed Zero around. This didn’t help his social existence. His monotone talking and the giant hovering snake things made people fear and hate him. Zero realized that he wasn’t meant to be around other people and decided to just be with his manifested emotions. Zero joined the League of Legends and now fights alongside his old enemies feeling nothing, completely empty.
Remember if you somehow see this these are all very basic ideas so don't judge them too hard. Also sorry for the lined paper splash art i wish i would have drawn that on plain white paper.
