Champion Concept - Omen, the Impaler

Hi. This is my version of Omen I would like to show you. Think you saw a lot of them, yet hope mine would get through to you.

So basically, there is Story. Story of great danger, that prophet Malzahar saw in one of his visions. Creature, that is not about hunger, terror or killing. The last one known to be remaining of it's kind. King. Their very existance in void centered around dealing pain and suffering, which begun from their inability tu work as pack. Though possesing intelligence equal to human, they are far from any living creature. Mercy? Compassion? Even amongst Void creatures they were feared of. Somehow he found out how to escape from this prison. And the day, when noone would be safe, will come. Fear, people of Runeterra. As noone else can be safe now. So..story of Big Great Something, that could be a breed of dog and porcupine, yet this point is not this important now.
