Being an avid fan of the Harry Potter franchise, I should have known about the character of Delphini, but I only recently learned of her. I am fervently against the mere existence of this character, and for one simple reason.
For those who may not know still, Delphini is the daughter of Voldemort. Yes, you read that right… The daughter of VOLDEMORT! She is not a fan-made character, and the story she appears in – Harry Potter and the Cursed Child – is not a fan-fiction. It is canon, somehow…
Voldemort would NEVER conceive a child under any circumstance. It completely contradicts the very essence of his character. He literally lacks human emotions like love and empathy, and there is absolutely no evidence throughout the entire Harry Potter series (or reliable outside sources) that Voldemort could be subjected to lust. Not to mention, he rejected Bellatrix’s advances. He didn’t care that she was obsessed with him. For crying out loud, he killed Snape, whom he immensely respected and fully trusted, simply because he believed Snape was the Elder Wand’s true master. How the actual fuck could anyone, for one second, believe that Voldemort could one day go up to Bellatrix saying, “Hey, I’m feeling a little frisky. You wanna…?”
So, I am to believe that Voldemort went a whole 70 years without getting laid, and then suddenly, for no reason at all, he decides to hook up with a chick?
I don’t know how the fanbase has reacted to Delphini’s existence as of this moment. I haven’t looked into it. But, I would expect and hope they would reject her outright. Just because Delphini was created by JK Rowling herself, that doesn’t mean she knows what the hell she’s doing. Sometimes fans have to confront the creators of franchises they love. Fans of Star Wars rejected the prequels, even though the prequels were made by George Lucas himself, and fans of The Godfather rejected the third installment even though it was made by Coppola and Mario Puzo. It doesn’t change the fact that these things exist, but time has shown that fans can certainly make things illegitimate and almost universally ignored.
Delphini does not exist. Period.
