Bruce Banner, also known as the Hulk, is a founding member of the Avengers in this continuity. He wields immense superhuman strength, durability, and regenerative capabilities when transformed into his large green alter ego. Emotional stress typically triggers his transformations, though he demonstrates a degree of control over the Hulk persona.

As an established Avenger, Banner participates in team missions and security operations, such as safeguarding the transfer of the Red Skull. During these missions, the Hulk clashes with adversaries like Ares and the Absorbing Man. Following the Avengers' decision to train a new generation called the Future Avengers, Banner assumes a mentorship role. He works with Makoto, Adi, and Chloe, genetically modified teenagers formerly manipulated by Hydra.

Banner connects deeply with Makoto, relating to his struggle to control newly acquired superhuman abilities, stemming from Banner's own experiences managing the volatile Hulk. He understands Makoto's challenge to harness his powers responsibly. During training exercises and real-world incidents, Banner and the Hulk provide guidance and combat support to the young recruits. For instance, when the trainees protect children during an attack on Avengers Tower, Banner operates alongside them. He later assists Thor and the Future Avengers facing threats like Enchantress during their visit to K'un-L'un.

Banner maintains his scientific expertise, often collaborating with Tony Stark on projects like prototype portal technology. These experiments sometimes lead to unintended consequences, including incidents triggering Hulk transformations during testing. Banner exhibits caution regarding his transformations, particularly after events where the Hulk's emergence caused significant property damage or public concern. His presence within the Avengers provides stability and experience to the younger members as they confront ongoing threats like Hydra's Emerald Rain Project and the Masters of Evil.
