Champion idea

League of legends character Humanoid He has a scimitar (without the hilt) like blade strapped to have the blade be on the inside of the arm. He is a void being Passive: every time he kills a unit he takes their soul as it leaves for the void and he gains really small bonus's to his AD (or AP if you decided to make him AP) Abilities: Q: slashes his arm forward and his swing radius is extended by this purple blue-ish cloud and he deals damage in front if him. W: he smacks the ground in front of him with his whole arm blade, causing this purple glowing crevice of light form straight forward to where the summoner is pointing damaging everything in it's path. E: purple blue-ish glowing/foggy portal forms directly in front of him, and a gate opens a few pixels in front of him, kind of like a flash. R: targets one enemy champion, sends him and the target into the void, but they stay where they are on the map. A black cloud that is completely visible and it doesn't cloud ANYTHING surrounds them and the become there characters but in a wierd white outline. Only him and target enemy champions. In the void these two can only attack eachother, though the enemy champion gets some debuffs. And no one from the outside can encounter them, IN ANY WAY. For a few seconds. This is all I will give you for my ideas everything else I leave up to you.
