A Lore for a Champion Idea No skills included

Throughout my life, people called me a failure. The kids, strangers , everyone in the community. Even me own parents look at us in shame, because we did not posses the "Magical abilities" needed to be strong. Are they not suppose to love you no matter what, but yet they could care less if I died. But no matter how hard I tried to forget I still needed to have their approval. So I went off wondering around looking for ways to improve my magic into i got to the point of being exiled. Then as I gave up and a man approached me floating with a spider looking thing, and promised me power if i gave him my loyalty. We, I gave in and I was no longer a single being. I became we. No longer did we want approve, we wanted to destroy. YOU CAST US ASIDE, YOU DID NOT LOVE US FOR WHO WE WHERE BUT OHHHH. How did you praise sister. Always telling me to be more like her. She is a prodigy they said, she can change the world they said, you will never be like her they said. Never even bother to tell anyone they had a son. But we are strong now. And she cannot change what is no longer here. As we sit on these two corpses , we think of these things. Our first goal is complete. To think we wanted the approval of fleeing cowards. But we need to do one more thing before we destroy this world. We already had a wonderful time with our parents so what do you say sister, Want to play too? it will be fun.

My Hope for him would be He is a physical ad assassin.( even though he is connected to the void) He posses two personalities( Happening from being introduced to the void) His resource would be pain (The way it would work is that by dealing damage it will increase his pain and once he hits 500 he can develop 1 of his four skills similar to khazix but the only difference is he can either develop (evolve) q one time or develop (evolve) it 3 times and leave his other abilities as is. He would be able to develop one skill a maximum of 4 times and only get 6 develops.) This it to add diversity to his game play so that you can mirror match and by mid game you don't even feel like you two have the same champion.
