The Iron Iapetus is the latest in a line of heroes started by the Gold Guardian. Like the three heroes who came before him, he can control the element in his name, and cause it to do a wide range of tasks from building machines, to becoming weapons, to taking on a semi-life of its own.
Iapetus has recently found out that he is running out of time so has rejoined Redoubt to find his successor as the Bronze Battler found him before he retired from the good fight.
