I've been studying this for four years, and there's a LOT of evidence that the origin of the Boxxy character is in anime. Specifically, since 2010, I have long believed Boxxy was originally a live action version of Catie's GAIA avatar. If I was Addi, looking at the first Boxxy video without any explanataion, that would be the only conclusion. Even the Boxxy makeup suggests anime eyes.
Catie has told all about how she was obsessed with anime, but she never acknowledged that Boxxy was inspired by anime. I think this is because she didn't want to step between the fans and what Boxxy means to them, or perhaps Boxxy means something different to Catie, who, like every 21 year old, is embarrassed by her middle-school self. (See "Letter to my 13 year old self").
Of course, there was also the factor of "mystique", an expression that Boxxy used in "FOAR EVERYWUN", which I believe is often misinterpreted. Here, I think it really means "the fun of figuring it out yourself." While Catie has never actually acknowledged that Boxxy was based on Anime, I believe she's been leaving a trail of clues for the past three years, from her choice of Halloween costume to an anecdote in which Catie actually made up Priyanka to resemble an anime character.
I think FOAR TOM represents Boxxy's debut as a human rather than a transcribed cartoon.
And I love it! The first four Boxxy videos showed an amazing growth of Catie's ability to focus and control her facial performance. FOAR SVETLANA was an astonishing human cartoon, but the fans wanted a Boxxy they could have a crush on. For the last couple of years, it seems like Catie has been struggling to resolve the contradictions, and maybe losing the struggle, but now...
FOAR TOM makes me realize that I've never really cared about Boxxy before. It was always about the intelligence that moved her. Back in the bad old days, I could see the precocious girl, winking at me from behind the mask, and I wondered if she was all right. But this time, it's really Boxxy. Catie has disappeared. Like Pinocchio, she's become a real live girl.
