What Came Out of Siberia (слэш)

In a world where the Avengers have big flashy powers, nobody knows the Avengers' eccentric benefactor, Tony Stark, has the seemingly innocuous power of being able to heat water. And no one knows he's actually Iron Man either. After Loki kidnaps Tony Stark and traps him in ice to lure out the Avengers, Tony reveals his power and escapes. Loki takes an interest since Stark reminds him of himself. And after all, a human is 60% water. Set early in CACW.
based on TheDukeofEnunciation's (writing.prompts.re) prompt: "You have been an under appreciated intern for a group of superheroes for a while. Your powers? You're able to heat up water to the boiling point. All you've done thus far is make the team their tea while they chill at their hideout. Unbeknownst to them though, you've actually got dreams of becoming one of the greatest villains ever. After all, a human is over 70% water."
sorry guys, don't think I'm going to complete this
