Avengers characters - ranked 8. Iron Man

Played by: Robert Downey Jr

The leader of the MCU used to be its greatest character. But with the influx of newer additions, Tony Stark has been pushed down that list – which isn't to say he isn't still a reason why the series has been such a success. No Marvel actor has thrown themselves into a role more than Robert Downey Jr, whose larger-than-life personality made him the only candidate to have brought the billionaire industrialist and former playboy to screen. Among the big-budget explosions, he's a breath of fresh air and without him, the MCU would have run out of steam long ago.
