The broad (0.4-100 keV) bandpass of the X-ray astronomy mission Suzaku and its high-throughput CCD detectors in the Fe K band is now allowing us a significant advance in understanding the nature of the X-ray reprocessing in obscured AGN. I will illustrate these capabilities with new results of the X-ray spectra of obscured AGN ranging from relatively bright and mildly obscured to the extreme case of a Compton-thick source hosted in a Ultra Luminous Infrared Galaxy, for which we have been able for the first time to unveil the power of the AGN.
