The Avengers found that a certain lullaby, typically said by the Black Widow, was able to calm the Hulk and help him revert back to Banner, when the Hulk's strength was no longer needed.
It has been established in both Age of Ultron and Thor: Ragnarok that Natasha is the only Avenger who can calm down the Hulk when he's in a rage. Thor epically failed at Hulk's lullaby in the Ragnarok area scene, a moment which got a lot of laughs.
Despite his immense power, the Hulk has been defeated by heroes like Wolverine, Iron Man, Puck, and the Punisher. Spider-Man, Fantastic Four, and the Thing have also managed to take down the Hulk using their intelligence, teamwork, and unique abilities.
The lullaby was introduced in Avengers: Age of Ultron as a way of reverting the Hulk back into Bruce Banner after a successful mission. Natasha would slowly approach the Hulk and gently touch his hand, saying “the sun's getting real low.” This would calm Hulk down enough to change him back into Banner.
Cyclops' brother, Havok, is one of the few Marvel superheroes who can defeat the Hulk in a fair fight. Alex Summers aka Havok may not be as popular as his more famous brother, but he is easily one of the most powerful mutants in the Marvel Universe.
