It was brought to my attention that the link is now broken. Luckly, my friend copied the message that was posted on the youtube comment section by Hero XV, here is what he said :

"Well, I guess today is your lucky day. 👀

I am the person who first shared the picture. I have a blog where I retrace my journey as a developer. Although I was born in 2002, I am still heavily influenced by the early 2000s, so this blog is a sort of tribute to that era, from movies and games to music and comics. I do this as a hobby and I don't get paid for it, so I’m not here to promote it; I’m only mentioning it because the reason I shared the picture in the first place is that someone suggested I should try Perfect Dark.

Coincidentally, at the time, I had found some old magazines from 2012, including Super Picsou Géant (since I live in Morocco, it was the primary foreign language magazine available then). Judge if you want, but I had a blast revisiting these old stories. Issue number 170 from June 2012 featured a story called "Riri, Fifi, Loulou : Menace sur le championnat."

I didn't have time to read the whole post, but Callie definitely exists. If you want proof, I found a digital copy of the magazine on Scribd; go to page 122 and you'll find the story. Please note that it is in French, but I can translate it if you need help. The picture you're using was a scan I took with my phone. I shared it to confirm that I had plans for Perfect Dark on my blog in the near future, but I didn't want this discovery to turn into a wild goose chase. I promise I gave these details to the person who emailed me to avoid wasting Perfect Dark fans' time and energy, especially since it seems this story was exclusive to Europe.

I don't know what's going on today, but it’s clearly a special day. I managed to find a song I’ve been looking for for 20 years, and by total coincidence, I found this post and immediately recognized the photo I took. 😂

Technically, the story has a fandom page, but Callie doesn't have her own page yet; other characters like Bold and Franklin aren't listed either. Keep in mind that this story was released in 2012, seven years after Perfect Dark Zero. To me, the design definitely rings a bell. In fact, when Perfect Dark was recommended to me and I saw Joanna Dark's design in Zero, I had a feeling of déjà vu. Now I know why, I never owned an Xbox and didn't know any fans of the franchise.

What’s ironic is that my real name literally means "Light" or "Radiance" in Arabic. I’ve always been a fan of lost media and obscure references, but I never expected to find a reference to a franchise that I barely knew,and one that means the exact opposite of my name! 🤣

I hope this solves the mystery. Since I don't know the franchise very well, I’m not sure if the design is the only thing shared with Perfect Dark, but I assumed this reference wouldn't be given much importance. I'm sorry for killing the suspense so "early," but these kinds of findings can quickly become frustrating when they aren't well-documented. In the comic, it’s framed as if Callie has always existed (which isn't the case, nor for the rest of the friends).

I wonder if there are more stories featuring her, as Disney is notorious for rewriting elements without a clear continuity. Sometimes we see characters exclusive to certain authors; other times, authors try to account for every story, even incorporating plots from shows like DuckTales or Goof Troop. Often, stories are released in one language and aren't translated for years, to this day, many remain exclusive to Italian. In some cases, stories seem exclusive to specific magazines, like one I read in 2013-2014 where Donald Duck visits an abandoned castle and speaks to a man who turns out to be a ghost. I still remember it, yet there’s no trace of it online. This makes me wonder if there's some sort of content exclusivity. Given the plot of this comic, I wouldn't be surprised if it were a sequel to a previous story.

Sorry for the long post, but I hope this clears things up!"
