He had all of frustration, his anger bottled up inside him for so long. Silently until one day it let it all out.

Attracting the attention of a object that used all of his and others violent impulses. Making him able to expel it, and use it on others. To create and destroy things with just a thought.

" Do not mention the blood. It's my own."

" The blood I vomited out  burned through it..gross but true.."

"...With blood and rage of crimson red..."
