Mirror Match/Playing With

Basic Trope: Two of the same character fight each other.

• Straight: Two identical Alices exist for some reason. They fight.
• Exaggerated: Alice can't even see anyone who kind of looks like her, or even an actual mirror, without trying to beat the crap out of them.
• Justified: One of the Alices is her Evil Twin from the Mirror Universe.
• Inverted: Screw Yourself.
• Subverted: One Alice turns out to actually be Carol wearing an Alice mask.
• Double Subverted: So does the other.
• Parodied: Alice beats up somebody wearing a Paper Thin Alice disguise. They do a Fearful Symmetry anyway.
• Deconstructed: The two Alices get into a Fearful Symmetry match, ending in a Double Knockout. Repeatedly.
• Reconstructed: One Alice catches on after the second or so round, and makes a backwards move that causes the other Alice to stumble over a curb that wasn't present on the first Alice's side. With the symmetry broken, the match proceeds.
• Zig Zagged: ???
• Averted: The two Alices get along quite well.
  • Or Alice fights against a completely different person that has no significant similarity to herself.
• Enforced: "If we're introducing an Evil Twin for Alice, you know we have to have a fight between them."
• Lampshaded: "Seems there's a clone of Alice running around. Bet you ten bucks they get into a fight."
• Invoked: "Hey Alice, I just found out the other you is sleeping with your boyfriend."
• Defied: Characters conspire to keep the two Alices far, far away from each other.
• Discussed: "So who do you think would win in a fight: Our Alice or the Mirror Universe's Alice?"
• Conversed: "They're doing a Mirror Universe episode. You just know they're gonna have Alice fight her counterpart."
• Played For Laughs: See Deconstructed.
