Smart Hulk

Smart Hulk (also commonly known as Professor Hulk) is a merged version of Bruce Banner and the Hulk. He is the result of Banner spending 18 months in a gamma lab, successfully combining the massive strength and indestructible body of the Hulk with his own brilliant mind, calm demeanor, and identity. In Avengers: Endgame, this new fused personality allows Banner to enjoy the best of both worlds: he gets to retain his human intelligence and emotions while possessing the giant, green, superhumanly strong body of the Hulk. Key Characteristics of Smart Hulk: The Fusion: Unlike their previous adversarial relationship—where Banner and Hulk would fight for control of the body—they now form a single, unified entity. Appearance & Personality: He is physically huge and green like the Hulk, but wears shirts, speaks eloquently, and is a celebrity who is happy to pose for selfies with fans. Crucial Role: His combined brain and brawn are vital in Endgame. He is the one who builds the time machine, operates the Nano Gauntlet, and performs the "snap" to bring back half of the universe's population who were dusted by Thanos.
