Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I know! I was surprised, too! The funny thing is that shortly after I nicknamed my Celebi "The Doctor", I watched a review of Pokémon 4Ever and they used the TARDIS sound for Celebi.
The reviewers did, not the actual film. And Trunks is a great reference. And now I realize that Rowlet's beak reminds me of Imperfect Cell's. Which makes me love it more.
Rowlett's probably going to be the only competitively viable starter, was originally going Litten but with the Bottle cap stuff I want my starter to be competitively viable.
I've never worried about that. For me, I let my championship team retire (they earned it after saving the world and defeating the Elite Four) and let them help me train the next generation. That's my head canon.
