The broken savior

My mother wasn't a mutant she wasn't born with the gift of evolution but she knew Charles Xavier from the past they shared. He ignored me at my mothers bequest due since mutants were a secret the majority of the world knew nothing about, she didn't want me in the institution.
A week after my 9th birthday one night, I woke up to the smell of burning wood and furniture, I looked for my mother but saw a horror ill never forget a swirl of shadow had her in its hand. She was bleeding from her mouth and nose, when I went to help the shadow smacked me into the wall. My mom screamed in pain as I watched her turn into orange dust.

The shadow spoke to me
"Happiness is a lie. Life is horror. The light is always dying, all across the universe. The last star will flicker out someday. When it does, all that remains... shadow. And I will be its king, You have Xavier to thanks for this... "

As it got closer I raised my hand and screamed a burning pain emanated from my hand and a bright light submerged the house... destroying 12 square blocks

where were Xavier's X-men no where.
