It can be sleepy Tony, stumbling into the kitchen for coffee or off to bed.
Or mechanic Tony, in black tank tops and bending metal and machines to his will.
Or businessman Tony, competent and shrewd.
Or silly Tony, clinging to Rhodey like a koala bear or pouting at Pepper or playing with his bots.
Just something fluffy and the Avengers coming to learn the different sides of Tony and appreciating him for who he is. Any, or no, pairings is fine.
