Bob's personality is that of a classical hero. At his core he desires to be a hero and paragon, and to do good for its own sake. But as shown in newsreels, Bob is physically invulnerable, but all to human in his flaws. He grows weary of a world that won't stay saved for more than five minutes; and later, shows a streak of hubris and arrogant pride, seeking to relive his glory days at the expense of his family life.
