It's unlikely that terror comes to mind when you think about Nintendo. That's why a lot of people are a bit offended when they see the author of Mario uploading a new, enigmatic, and eerie video. Furthermore, we have no idea of what it really relates to.
The kind of games Nintendo is renowned for are well known to everyone, so this little horror teaser that only poses the question "who is Emio?" is pretty mysterious. Though not much is shown in the brief 15 seconds, what is is sufficient to start a conversation.
The only thing we see is a shadowy man wearing a basic trench coat. Their frames are just slightly lit as they lean against a wall. However, we aren't attracted to it. The paper bag with a hand-drawn happy face on top of their head is the most unnerving aspect of this clip. Why is that thing grinning? Grocery is something you carry in bags!
Is there a connection to the Nintendo/Bloober Team collaboration?
It is not my intention to assign meanings to you. Everyone has their own theories, I'm sure. If you're interested in reading what other people are saying about this Emio persona, check out this Reddit thread. To be sure, the Nintendo website itself doesn't provide any further information.
Still, it's not impossible to draw the conclusion that it has anything to do with Bloober Team. Listen to me. In essence, this interview (Google translated from Polish to English) with Piotr Babieno, the CEO of the company, does touch on a new project that the horror developer is working on for "Nintendo platforms."
So, is this a brand-new horror IP from the creator of Layers of Fear? I would want to reiterate that this is just conjecture on my side. unadulterated and basic. Nonetheless, there's something very intriguing about the timing of the Emio teaser and the interview. But keep in mind: conjecture. Not a thing more.
That being said, Nintendo is not entirely out of the question to sometimes dance with the scary monster. I'm not referring about Luigi's Mansion, however. Many may recall Eternal Darkness, a survival horror game unique to the Game Cube that almost developed the sanity system that would be made ubiquitous years later in Amnesia: The Dark Descent. It's not like Nintendo is scared to go into the eerie and dark—after all, it published that.
As of right now, it's a lighthearted little teaser that's getting everyone excited about potential future projects from the team behind The Legend of Zelda and Donkey Kong. But also Mario 64, with its enormous, cracking piano.
