Born Better
God of Lightning
I think he knows, he just wants to emphasize on Gladion ("The Edge") appearing, which in his eyes signifies the "plot" being here", by feigning ignorance of the Japanese names of Rockruff and Lycanroc. Just look at his signature, he uses the Japanese name for Hawlucha, so I'm sure this person is aware of what most of the Japanese names are, especially for one that's been captured by Ash.
The first part was a legitimate question. I don't keep up with the Japanese names. And I figured that poster was Hawlucha's Mexican name or something considering it's well...a Lucha poster.
And I'm really not sure how me asking about Japanese names has anything to do with me commenting on plot.
Also, when the hell is the dub coming? I can't wait to see this, but I absolutely refuse to want Pokemon in Japanese.
