Mascot and Fans[]
- Isaa's fanbase is known as the Crownuts. They are represented by a round, oval, dodgeball-sized, dark-blue bird/crow mascot with 3 head feathers. Additionally, the crownuts ordinarily have nubs for arms+legs, no talons or wings.
- Her community is interchangeably called Crow Nation or the Crowmmunity.
- The "Crownuts" mascot design idea was originally a Crow shaped like a donut. However, this had not come to fruition and instead followed a design Isaa had drawn on stream in MS Paint.
- The Crownuts are known to have a large quantity of cake. It is their #1 export.
- The Crownuts get dunked into dye like a Caramel apple to change their feather colors
- The Crownuts occasionally change shape- such as gaining human like hands or feet, losing their beaks, or gaining wings and/or bird talons. Canonically they are technically homunculi that took the vague shape of a crow. They occasionally shape shift into blue-crow hybrids of another animals like Fishes or Kangaroos.
- The Crownuts have teeth.
- Isaa has 2 stream pets:
- Noodle: a fluffy gray cat who sits on her left shoulder, who coincidentally resembles her real-life cat (Noodle predates Frog), Frog before she had gotten her (frog). However, Noodle had only shown up on stream a single time during her 3.0 debut stream. This has led many fans to mistakenly believing that the emotes made of Noodle are emotes made of Frog.
- Timmy: a particularly unhinged Crow with a TTS voice, who Isaa says reflects chat. Unfortunately, Timmy has passed away due to the TTS bot breaking.
- Isaa has 2 pet cats, named Frog and Bear.
Trivia[]
Name[]
- One of Isaa's old namesakes, Isavtuber, was a pun as it also reads 'Is A VTuber'. However, this led to many people pronouncing her name wrong. (It is pronounced ee-suh.)
- The reason why Isaa Corva's name is Isaa (2 a's) and not Isa (1 a) is that there is a 4 character minimum for most streamers. Because the "vtuber" part was being dropped from her name, an extra A was added to reach the character minimum.
Lore[]
- Isaa has heterochromia. Her left eye is orange (previously brown), and her right eye is blue. This was chosen because the American Crow (Corvus brachyrhynchos) has bright blue eyes as a juvenile, which become brown when they reach full adulthood.
- Isaa states that she cannot fly, but canonically she can indeed achieve considerable lift by rapidly flapping the wings on her head like Dumbo.
Models[]
- Starting with Isaa's 2.0 Live2D model, and lasting all the way through to her 3.0 model, she had had the surprising feature of having fully rigged toes (they were not a feature that was commissioned, in fact it was paid for by one of the people working on the model), a feature which she says she hated, but chat enjoyed quite fervently. Chat was saddened immensely when they were informed that her 4.0 model would not have ANY toes, fully rigged or not.
- Her 3.0 model has been dubbed the "Beach Bum" model.
- Isaa's left eye officially became orange with her 4.0 model.
- In Isaa's 4.0 model, she gained 2 additional wings on the right side of her head.
- Subsequently, in Isaa's 5.0 Model, she lost 1 of of those additional wings and instead gained 2 on her boots. (A total of 3 on the head, 2 on the boots).
- The 5.0 model, despite being a 5.0 model, is also Isaa 2.0 (2nd model of modern Isaa), 4.0 being Isaa 1.0.
Miscellaneous[]
- Isaa has a vocal range of C3 to F#6, which is 3 octaves and 6 semitones.
- Isaa has a "Raid Song" she wrote that she sings to thank & welcome in raids coming in from other streamers. It is very popular within the Crowmmunity, many of which it is the reason they followed. However, nowadays the "Raid Song" is only sung if she is raided on her weekly "Music Monday" streams.
- In the past she used to frequently stream Fortnite, Valorant, Apex Legends, and Dead By Daylight. Over time, she began to stream many more Just Chatting streams, after her 4.0 model subathon improved her stream endurance.
- The on stream !awesome counter is currently at 1802, this counter counts how many times Isaa has said Awesome on stream (began counting April 21st 2024).
