The show follows Dr. Bruce Banner, a scientist who, after being exposed to gamma radiation, transforms into the Hulk whenever he gets angry or stressed. Throughout the series, Banner is on the run from the military led by General Thaddeus "Thunderbolt" Ross, who sees the Hulk as a threat to national security.
In his Hulk form, Banner has superhuman strength and durability, making him a formidable force against any threats that come his way. Despite this, Banner is constantly struggling with his violent alter ego and tries to find a cure for his condition.
She-Hulk, a.k.a. Jennifer Walters, is Bruce's cousin and a lawyer who gains similar powers to the Hulk after receiving a blood transfusion from him. She joins forces with the Hulk to help him navigate his new life as a superhero while also dealing with her own struggles and challenges.
The Grey Hulk, also known as Joe Fixit, is a separate personality within Bruce Banner that emerges in times of extreme stress. This version of the Hulk is more cunning and manipulative, using his intelligence to outwit his enemies.
As the trio battles various villains and threats, they also deal with personal issues and relationships, making for a compelling and action-packed series that explores themes of identity, power, and redemption.
