Except he WAS lying. Madara stated that kabuto didn't "create this strength" and the harishima DNA was implanted by Madara BEFORE Madara died.
Also I agree that tobi is ALOT less badass without the mask. I mean with the mask, even though itw as pretty much confirmed he was, in fact, tobi he had an aura of malevolence and just breathed evil intent. Now he's ****ing talking way to much and while he ****ed kakashi up he got his **** slapped in turn(well, one or two punches but still).
