This idea was obviously meant to be a celebration of the past 20 years of Pokémon. From big things like the return of Gary and Mewtwo to smaller things like a recurring theme of the number 20 (by the way viginti, as in Project Viginti, is Latin for 20), it was all over the place. It would be too much to specifically go over every little joke and reference I made, but they should be easy enough to find.
The idea for this episode can be traced way back to before I had even considered writing Cosmic Quest, back to when Genesect and the Legend Awakened first came out. I’m sure I’m not alone when I say that I was immediately disappointed that the Mewtwo in the movie was not the same Mewtwo I grew up with. In all honesty, the Mewtwo present there was very disappointing. I wanted to watch a movie about a fierce and invincible demigod-like being with an inbred hatred towards humanity, not some random arrogant psychic lady who’s indifferent towards humans. But soon after that movie, with the existence of Mega Mewtwo X known, my brother and I came up with the theory that an upcoming movie would feature a battle between the two Mewtwo, with the original Mewtwo becoming Mega Mewtwo X. At this point, that ever actually happening seems extremely unlikely, as we are now at the end of Kalos’ lifespan, and it’s during Kalos they would want to use the Mega Mewtwo. But, I did realize soon after starting Cosmic Quest that I could work that idea into my own episode. As the 20th Anniversary approached, I decided that I wanted to do a 20th Anniversary special. I quickly realized that a battle of the Mewtwo would be a perfect anniversary plot.
In reference towards the name of the episodes, Attack of Clones, I want to explain my logic. I, one day, had a sudden realization that whenever Mewtwo pops up, it is in movie/special that has name that seems to be linked to a Star Wars title. It first appears in Mewtwo Strikes Back, similar to The Empire Strikes Back. Then it appears in Mewtwo Returns, like Return of the Jedi. And finally we have Genesect and the Legend Awakened, similar to The Force Awakens. Therefore, I could not resist making a Star Wars joke here, and Attack of the Clones was the obvious choice.
One last thing I have to mention is some last minute changes I made. I had actually finished both episodes the Wednesday before the anniversary, that means that they were complete before the announcement of Sun and Moon. I went in right before publishing the episodes and added the Sun and Moon references to both Team Rocket’s reward jokes and to Mew’s speech. Originally the reward joke (the one where they mention the names of every Pokémon game) had Meowth saying something about speculating that they’d be catching Z’s on beds made of money, as current speculation inferred Z was to be the next game. But with the announcement of Sun and Moon I changed the line to being about the Sun and Moon. To further the joke, I added the extra statement about never being able to catch Z’s as a jab at the fact that Z Version will almost certainly not happen.
The anniversary may be past us, but always remember to train on!
