Blade's willpower and ability to control his body allow him to outsmart and dominate even a being as powerful as Hulk in the final installment of the Marvel Cinematic Universe.

For those wondering who would win in a fight between Blade and the Hulk, the winner has not been determined by the story. The comic offers a standard team-up instead of a showdown, and the outcome is clear: Blade is the stronger of the two.
Blade's strength is undeniable, as his willpower and actual power surpass those of the Hulk. While Bruce Banner's immense rage and superhuman capabilities are undeniable, Blade's ability to contain monstrous entities within himself without completely surrendering to them showcases a different dimension of strength.
Blade can do what Hulk can't - he tricked the demon into entering an open field where the Hulk was waiting for them, allowing Hulk to smash the demon with ease.
Blade's possession reveals a disturbing truth—the moment confirms that he can do exactly what Hulk can't. Both characters, driven by the same primal desire to control their shared body, have expressed their desires to achieve complete dominance. However, while Hulk's insatiable rage compels him to repel unwanted intruders, Blade's cunning intellect and agility allow him to effortlessly overpower his possessed host. This unsettling contrast between the two titans suggests that their shared fate may extend beyond mere fraternal kinship.
