Peter Brady
Peter is the Brady's middle child. He has a fragile ego that manifests itself in extremes; often he lets his achievements go to his head while at the same time lets the little things get him down. He celebrates his rescuing of a little girl from a falling shelf of toys, calling himself a hero, but not long after decides he has no personality when some kid at a party says he's dull.
Peter is anything but dull. He may not be too great at fixing bikes or making ice-cream sundaes, but he builds a mean model volcano. He's also great detective and a pretty good reporter. Peter even proves himself to be a fine actor by playing Benedict Arnold in the school play, a role he later lives to regret.
