Bruce Banner is a physicist who was the victim of the explosion from a gamma bomb he invented. When under great emotional stress or angry he transforms into the Hulk.
He is often pursued by the armed forces; seen as a danger to the public. Bruce is a very intelligent man and wants nothing more than to find a cure to rid himself of the Hulk.
He loves Betty Ross even though her father is leading the manhunt against him. On some occasions Bruce is capable of fully controlling the Hulk but when not in control Betty is the only person capable of calming him down.
