I have indeed, anonymous! You don’t get to where I am in the field of pokémon technology without having your fingers on the metaphorical pulse of, well, pokémon technology—and the “rotom dex,” as it’s called, is certainly the innovation of the year. I’ve heard about it for months, ever since word first spread out of Kalos about its development, and believe me, since the moment I’d heard about it, I have always wanted to get my hands on one. Unfortunately, while I could easily get the shell, the rotom is the difficult part. Even with my connections, not a single one has a rotom to trade, let alone any definitive leads on where one might be (outside of Sinnoh’s Old Chateau, which is unfortunately spoken for in terms of a trainer).
That aside, it’s entirely possible. Being ghost-types, rotom are naturally mischievous, and they don’t lose all of their personalities upon possession of an electronic device. On the other hand, Alola is hardly the only region with morbid entries (for good reason, oftentimes), so in some cases, it may simply be the nature of the subjects themselves. This, quite honestly, is one of the many reasons why I would love to get a rotom dex of my own.
(The other reasons, of course, largely involve the idea of holding actual conversations with a ghost-type pokémon.)
