First, don't get me wrong. I did not mean to say you ridicule him. Yet still many people do. Especially when it comes to Aisha's love life. And I neither assume he is dead or he is alive.

Second, the Comics series somewhat belong to a parallel universe with the animated series, as Roxy is a part of the club in the comics but not in the cartoon series.

Third, there is a huge confusion of Season 4 and the 2nd movie's plot, as having Nabu appears in the final episode and the 2nd movie and many people still believe this is the error of producer, much like the Enchantix scenes. But talking back, Bloom once stated Roxy couldn't go to Amazon with them because she did not have Believix power (some cited this as she did not receive the gifts from the Ethereal fairies), but once in a poll, Rainbow stated she had Believix power. Some people tried to talk that the 2nd movie should be in a parallel timeline. But with producers, they have their own reasons choosing the airing time, especially when the ideas of having the 2nd movie was quite the time. In Japan, as people know, during the currently airing time, the air time of the movie and airing series are always in-order. They have been ordered in a fixed schedule. It makes no sense thinking something wrong just with people's beliefs and not from any official source. There could have been some explanation with Nabu's fate in later season, only if Nick did not interfere and messed things out.

So far so good, the confusion of Nabu's fate was still in there, and did not make clear, Nick only mess things out. I personally do not take him as dead or alive. He has gone. His on-screen time is over and they let things move on without making further explanations.
