Could somebody explain how Hoopa and the two others were found? I went to the GTS and requested a couple of random names and it accepted it. I literally typed gibberish such as "uhauhds" and deposited a Plusle. The game seems to accept any name - as well as Hoopa etc so why are we sure that Hoopa and the others are real? I know there was something with Japanese names being trademarked but is there more to it?
If you type in their names in all caps it will autocorrect to the proper capitalization, it does not do this for gibberish.
