The Spectacular Spider-Man: Natural Selection

Peter does a great job arresting shop robbers, bus ruins his self-pictures. When Dr. Curt Connors injects himself with lizard DNA to regenerate his arm, that works. Actually, too well: he soon transforms into a dino-like monster, whose instinct spares nobody, except his son Billy. Peter’s uncomfortable secret-identity-handicap now spills from bully-abuse at school to utter injustice in his lab job.
