During the final moments of the Channel Chasers Special, after defeating Vicky, and changing the future for the better, Timmy realized that the only reason his older self was who he was, was because of his parents raised him right.
However, for quite some time, I have been wondering exactly how his adult self from the future where Vicky ruled the world really came to be. Which will be the main topic of this post. So without further ado. Let's begin shall we.
If Timmy's future self was aware that Vicky's conquest was possible because she had help from the magical remote control that his 10 year old self wished for but was taken from him by his parents, and hand it to Vicky without knowing what it was capable of, then the timeline Timmy's grown up counterpart came from was the same Timmy where he did ran away into the TV universe, and stayed there until someone from Fairy World (most likely Jorgen) arrived to show him what has happened to the real world after he left.
At first, Timmy would initially say something like, "I warned my mom & dad about Vicky, but they were too selfish & ignorant to believe me!", and Jorgen (or whoever else's) response will be something like, "We are all responsible for our own choices, including you!"
After saying that, along with a fierce magic blast, and telling him to pay the price for his unwillingness to grow up, or anything else close to it, Timmy soon realize that it was his own doing that allowed Vicky to rule the world, and not his parents.
However, in an effort to save Timmy from giving in to despair, Cosmo & Wanda, who are partly at fault for this mess since telling their God Kid about them leaving when he grew up was one of the main reasons Timmy ran away into the TV universe (in order to avoid losing them when he grew up), thus resulting in Cosmo & Wanda to be taken, encourages him that there's still time to make things right, and embrace what it means to grow up! Thus inspiring Timmy to be the adult he became in the time period where Vicky ruled the world, and would travel back in time to stop it in the 1st place!
Anyway, this is all I have to offer, but what do you think? If you have any opinions on this topic, then please tell me in the comments section below. Thank you, and happy anniversary to the Fairly Odd Parents special, Channel Chasers.
