Iron Chef America recognizes the Iron Chefs from the original Iron Chef, though Morimoto is erroneously credited as having 66 victories in the original Kitchen Stadium as a result of a typo (he was, in reality, 16-9-1, with one victory coming in overtime). However, Iron Chef America does not appear to include Iron Chef USA in its history: when Iron Chef American Todd English appeared on Iron Chef America as a challenger, his record from Iron Chef USA was not reported and no references to him being an Iron Chef were made.
