This was under the Kurt Busiek/George Perez run. I remember Busiek saying that he was bulletproof. He clearly seemed to be powered down for Busiek's run, but how exactly was he bulletproof? Did he get shot and hit by bullets or something? While he did seem to be powered down, he was also able to take down and defeat (And almost kill.) The Presence (A villain who gave The Defenders and Quasar a hard time.) and help take on The Exemplars (Who were kind -of-like mini Juggenaut's.).
