Porygon2: A member of the clan Porygon making it onto her team was a given, but the big question was which one deserved the spot? Porygon2 ultimately made the cut because like Chiaki, it's slow and analytic, but also fiercely competent when the time arises; morose than any of its brethren. It's also fondly reminiscent of a bygone era, in a similar sense to how Chiaki's character is prone to making people strangely nostalgic about their past gaming experiences.
Wigglytuff: She absolutely had to have something to rep her lil' sis Usami, but the problem is that most rabbit Pokémon suck eggs. Thus, PK helped me choose a critter that ticked all the right boxes: pink and white colouration, big ears, fairylike nature, and caring heart.
Genesect: Of course Chiaki would go out of her way to find a Pokémon that changes cartridges to change the properties of its attacks. The female Genesect in the most recent Pokémon movie also had a feminine voice akin to Chiaki's, so they'd probably have some pretty weird conversations, I'd imagine.
Musharna: Chiaki's a big ol' sleepyhead, but not in the same kind of way as say, Snorlax or Slaking. Musharna helped rep her narcoleptic tendencies and her ethereal, metahuman nature at the same time, so it ultimately made the cut over its drowsy cohorts.
Scrafty: Chiaki is cool and adorable. Scrafty is cool and adorable. Chiaki wears a hood. Scrafty wears a hood. Chiaki is fiercely protective of her friends. Scrafty is fiercely protective of its friends. IT ALL CONNECTS!
Mega Slowbro: I actually made the decision to put this fella on her team before it was suggested in the thread yesterday, so I'm happy that you guys see the connection without me having to explain it. Just like Chiaki, Slowbro is quiet and reserved as well as a bit, well, slow on the uptake, and yet both still manage to be great assets to their respective teams as well as possessing immense mental strength and fortitude. I think they'd get together like two peas in a pod.
That's all for today, folks! Tomorrow we'll do Byakuya Togami II since he received the second-highest number of votes, followed by runner-up Ibuki Mioda on Saturday!
