After reading the threads regarding the last episodes of DP, I wanted to share a few thoughts about Vlad Masters/Vlad Plasmius..
I tend to feel that Vlad had three separate motives during the course of the show. During the first and most of the second seasons, he tried to get Danny to renounce his father and become a son to Vlad. Having failed at this on numerous occasions, he then tried to create a Danny clone so that he could have him as a son. During the third season, Vlad seems to want to acquire power and influence on a major scale, hence his becoming mayor, then trying to blackmail the world into making him ruler.
A few have expressed a desire for Vlad (as well as other characters) to have been give some more character development. While I understand that desire, I have to point out who created the series (Butch Hartman of FOP fame) and where the series was aired (Nickelodeon). The series definately had a FOP feel to it (sight gags and funny lines) but added some character development and a continuing storyline. Adding more depth to the characters might have given the show a different feel to it, possibly not a positive one. Also, airing on Nickelodeon, the target demo was 8-12. Nick would probably have frowned on adding a ton of extra characterization to the show, feeling it would have been wasted on its targeted audience. Avatar is the exception--not the rule...at least for now...
Even with Vlad's regret about revealing his secret, I don't feel he's a candidate for reforming. Perhaps if new episodes are made, there might be a chance, but not right away. I don't believe Vlad is gone...the asteroid scene and the music during it kind of leads me to think it was just a final payback for his actions. It reminds me of other times during the series he had similar payback (i.e. explosions, ghosts attacking him, etc.).
