Why did the Hulk's power decrease in the later stages of "The Avengers"? #usa#avengers #marvel

Description: Initially considered a top-tier Avenger, the Hulk later became a mere tool. In Avengers 1 and 2, the Hulk possessed incredible destructive power and a unique Hulkbuster armor. After being severely injured by Thanos in Avengers 3, the Hulk refused to reappear, displaying an independent personality and resentment that others only coveted his power. Later, Banner underwent gamma experiments, merging with him to become the Hulk, with Banner taking control of the body, resulting in a decline in his fighting ability. Even with his weakened state, he remained responsible, willingly taking the damage from the snap and risking his life to cover his teammates' escape. Close description
