- Archive Panic: Making certain voicebanks can induce this reaction, based off of how much is needed to record for it, especially those of foreign languages. The Japanese language only needs anywhere around 52 phonetic samples to make a CV voicebank, while a VCV voicebank can take anywhere from 100 to 200 samples, depending on how smooth you want it to sound. Want to make an English CV-VC voicebank though? Hope you're willing to record anywhere between 500 to over 1000 phonetic samples!note
- Broken Base: Ritsu's profile. Is it a parody of ridiculous Utauloid profiles in an attempt to get people to focus more on the music, or a serious background that needs to be stuck to no matter what?
- Fanon: Teto Kasane's official age is 31, but fans often retcon it into 15, explaining that she is "31 in chimera years".
- Similarly, Ruko's and Rook's official ages (12 and 13 years old respectively) have been retconned by fans into 19 and 20.
- Fanon Discontinuity: Nearly everything on Namine Ritsu's official profile is disregarded by the fans. This is probably justified in that he is officially described as a 6-year old misanthropic Jerkass who pads his chest with missiles (and thus weighs 25 tons).
- Also, Yokune Ruko's gender leans heavily on the male side, but due to the feminine appearance, fans still refer to them using female pronouns.
- Fridge Brilliance: Tei SCREAMS this. Using a lot of Hatsune's songs to usurp Hatsune, hardly using any of Len's songs so as to NOT usurp him, using other Vocaloid songs to take over, ect.
- Friendly Fandoms: Unsurprisingly, they have this with the Vocaloid fandom, to the point that the two fandoms nearly perfectly overlap each other.
- Hilarious in Hindsight: Ritsu, despite looking female, is supposed to be a male character and was advertised as the fourth in Crypton's Character Vocal series. Oddly enough, Crypton was planning to have a male vocal as their CV04... but he fell to the wayside and is indefinitely in a state of limbo.
- Idiosyncratic Ship Naming: The names of the most famous ships with Tei: Ten being with Len Kagamine, Tier being with Mayu, and Tension, being with Hatsune Miku herself.
- Never Live It Down: No matter how many updates are made to the program for smoother phonetic transitions or how much effort that was put into an Utauloid to make it sound extremely realistic, Utauloids are mostly known for being extremely robotic sounding in regards to Vocaloid, thanks to early resamplers being rather robotic sounding in general and CV for the longest while being the only recording style. Doesn't help that videos from this time tend to be the most popular ones on both YouTube and Nico Nico Douga. Though, some would argue the more robotic tone to their voice is part of their charm.
