John isn't the nicest person you'd want to meet. 

He used to beat his wife before killing her after believing she wasn't in use anymore and thought she committed a sin.

He also beat his child (Drake) for not being perfect at what he does. Which has traumatized Drake into adulthood, which he's still not very proud of Drake even a little bit.

John has a Fear Invocation ability. Which allows him to see a person's deepest fears and use it against them to terrify them.
