Avengers: Infinity War - 10 MCU Heroes Strong Enough To Face Thanos
7. Iron Man (With Hulkbuster Armour)
The Infinity War trailer showed Tony Stark, in his human-sized Iron Man suit, being knocked to the ground after just one Thanos-sized punch. Who knows what kind of damage that did to the suit, and if Tony loses his protective armour, it's game over.
But... he does have a better option. We already know the Hulkbuster armour is in Infinity War, and though there are rumours that Bruce Banner is the one piloting it in the trailer, is there any reason Tony can't use it later, or use a second one? No - and he should.
The Hulkbuster armour would give Tony a power level similar to that of the Hulk, and as we'll discuss later... that's a lot. A punch from this suit would genuinely affect Thanos, and considering Iron Man's ability to fly away from danger or retreat to a safe distance and fire off missiles and bullets, he's got plenty of tricks to keep his purple opponent busy.
The Hulkbuster suit is also incredibly durable and can withstand a hell of a beating, but the design of the suit is also the reason Iron Man isn't ranked higher; should Thanos damage the power core, Tony will be helpless.
Thanos seems smart so he'd surely realise that the glowing light in the Hulkbuster's chest is important, which means the fight could be over for Tony as quickly as it starts.
