Robert Downey Jr is the coolest person in the Marvel Cinematic Universe, much like Tony Stark. Well, RDJ is Tony and Tony is RDJ now, so it's not surprising. 

He's been here since the beginning, he has honestly made MCU what it is today and with 'Avengers: Endgame' being such a final movie for all the OG characters, he's probably very emotional and proud about it. 

He knows how much his fans love him and his character and that's probably why he's out there being so pure on his Instagram. The press tour for the movie is going on and he's still hellbent on entertaining everyone. 

Posting a video of himself dancing almost every day of the press tour, he really is proving he's the coolest.
