Kid Miracleman replaces Thanos at the beginning of Infinity War

At the beginning of Infinity War right after Loki dies Thanos and his Black Order vanish and Kid Miracleman appears in MCU Times Square.

He’s armed with the Power, Reality and Space Stones placed in the Infinity Gauntlet and knows what they’re capable of. He also knows where the other Stones are.

What happens next and how do the heroes respond?

How long until Kid Miracleman is defeated and how much damage does he do in the process?

MCU is ****ed.

Kid Miracleman brings a level of ruthlessness and viciousness that the MCU's superpowered villains frankly have never showcased. In a few seconds' time his fight with the protagonist's seemingly destroyed London:

Give him the gems and he'd immediately destroy most of the world and leave no one left to stop him.

Alan Moore's run on MM was a hell of a thing.

I don't understand why so few use narration in comics.
It just ****ing works!
