Hulk

David Banner is a genetics researcher for the government trying to improve human DNA; his supervisor, General Thaddeus "Thunderbolt" Ross, forbids human experimentation, so David experiments on himself. His wife, Edith, soon gives birth to their son, Bruce Banner. David realizes Bruce inherited his mutant DNA and attempts to find a cure. After discovering his dangerous experiments, Ross shuts down David's research; David rigs Desert Base's gamma reactor to explode as revenge. Believing he's dangerous, David tries to kill Bruce but accidentally murders Edith when she gets between them; the trauma causes Bruce to suppress his early childhood memories. Ross arrests and sends David to a mental hospital and puts the 4-year-old Bruce into foster care. Mrs. Krenzler adopts him, and Bruce assumes the surname, growing up believing his birth parents are dead.
