I wear this mask not because I'm afraid of people to see my face
I wear this mask as a symbol of revenge, justice and fear
because as soon as people see this mask they know that it will be the last thing they saw.
they try to run, they try to hide, but it's too late for them, because I'm the spirit of death, I'm the grim reaper, I'm the Shy Guy

Looks like a Resident Evil 4 enemy, and that's awesome.
