Downplayed: Dark Pharaoh has Bob's mild mannerism, but doesn't hesitate to point out egregious things when asked, unlike Bob.
Justified: The story revolves around the members of a certain image board trying to reveal government conspiracy. Being anonymous assholes are expected.
Dark Pharaoh is a total loser (that Bob uses as a strawman).
Bob aka. Dark Pharaoh is more mild mannered & cautious online then he is in Real Life.
Subverted: A forum member named Dark Pharaoh seems to be edgy and snarky, which the other members take as normal. However, when the forum have a Real Life meet-up, Bob is as edgy and snarky as the Dark Pharaoh.
Double Subverted: The edgy and snarky Bob is just a facade for the timid and indecisive William Waddington Jr.
Zig Zagged: The edgy and snarky Bob turns out to be the real persona after all, and the timid William Waddington Jr. persona was just an act, as part of an elaborate scheme to seduce a girl who isn't into bad boys.
Parodied: The sheer over-the-topness of Dark Pharaoh inspire people to make a Dark Pharaoh Facts.
Averted: Every online persona/magical avatar/component soul behaves in civil manner.
Lampshaded: "Oh boy, yet another totally uninhibited virtual dickhead who lives in momma's basement."
Invoked: Bob always wanted to be edgy and snarky, but that would bring many consequences to him in the real world. Online anonymity allows Bob to fulfill his wish through his Dark Pharaoh persona without having to worry about said consequences.
Exploited: Bob is an Attention Whore. He uses his Dark Pharaoh persona to get as much negative feedback as possible by being edgy and snarky with the other forum members.
