Ok, I really don't think Mag Mel and Razenoid are gone because they wouldn't just completely change enemies halfway through the series. Sure, they replaced Spectra with Zenoheld halfway through NV, but they kept the Vexos, plus Spectra was still a villain, just not the MAIN villain, plus Spectra was supposedly working for Zenoheld the whole time. Also, Dylan's lollipop was pink, not blue. Does this mean anything? Lastly, I agree with the people saying the Zenthons aren't dead. Why? Because Dan and Drago can just re-summon them, no matter what defeats them.
