I heard that if you draw something usually cute and cuddly looking evil and dark, it may disturb the watcher. I agree.
Now, this form of Raven only comes out when someone he loves is in inescapeable danger and he's too injured to help.
Ex: If Willow is cornered by Wrath while Raven unable to move and Savior is out of it, Raven's demonic will take over for his safety and those around him. Only downside is that Raven acts like a demon, Only way to get him out of this form is to knock him out ._.
