[Wait I'm using the word wrong, am I? I just want to know before someone bites my face off. But hey don't you get it? ironic? hahaha] [Also, Love Never Dies sucks, but it has wonderful music. I WANT MY PSYCHOTIC PHANTOM BACK. Also why did Raoul turn into an *******.]
Yeah, you used it wrong. That's not ironic, it's fitting. Irony would be if Iron man were made out of steel. Because his name is IRON man. It's not ironic that he's made out of iron, or that he's doing the ironing, because it's what you'd expect. There's also dramatic irony, which is when the audience knows something, but the characters in the play do not. (e.g. Juliet is actually asleep, not dead.)
I hope you're your knowledge of Iron Man doesn't consist solely of the films and the new Avengers cartoon.
