Tony Stark

"Kevin, will you just do what I tell you to do and introduce yourself to Tony Stark?"

-Captain Sauce

Before episode 1
Before the series started, Tony moved into a house with the rest of the Avengers.

In the main series
Kevin first met Tony in episode 2, where the Iron Man bragged about sports cars and baseball. Soon after, Thor came and talked about art. Kevin, however was more interested in asking about the weapons Tony produced in the past, believing that he sold Thor one of them.

Strangely enough, he didn't turn up at Kevin's party later in the episode.

Thor Odinson
It seems that Tony made some weapon for Thor. Perhaps in this universe it was him who forged Stormbreaker?

Personality and Traits
As expected, Tony is quite proud and still has his collection of cars, however he doesn't seem to like parties as much anymore.
