Wasn’t Syndrome like a huge fanboy when he was little? So like, he’s probably holding his OTP in his hands and this is one of his fanfictions that became real.
I don’t think Mr Incredible x Elastigirl was his OTP because he looks pretty pissed… maybe he shipped different parings?
He probably didn’t ship Mr Incredible with anyone. Because Mr. Incredible worked alone, and it would be OOC for him to have a relationship.
That’s probably why he’s pissed: This pairing goes against canon, and he’s the type of fan who hates that.
his otp was obviously Mr. Incredible and Frozone
