Batman: Mask of the Phantasm

A young Bruce Wayne meets Andrea Beaumont while visiting his parents' grave, and they form a deep mutual attraction. That night, in one of his first crime-fighting attempts, Bruce foils an armored car robbery, but is discouraged because the criminals did not fear him. Bruce decides against avenging his parents, feeling he should do what they wanted had they lived to see him as an adult, and proposes marriage to Andrea, who accepts. However, Andrea mysteriously leaves Gotham with her father, businessman Carl Beaumont, ending her engagement in a "Dear John" letter. Believing he has lost his last chance of having a normal life, Bruce becomes Batman.
