Appearance
Radia is a 13 foot tall scorpion woman. She has black hair with radioactive green tips, her eyes have black sclera, and she has mandibles around her mouth. She will usually have her scorpion tail and her pair of pincers out, but may put them away to make room on stream. And of course, she has giant scorpion legs. She may occasionally take a human form, at which point her monstrous qualities are hidden, including her height going down to 6 feet.
Her usual outfit is an open white office shirt and black skirt. She wears glasses, a necklace of unidentified glowing green liquid, and her employee ID card.
Background
Her Twitch channel was registered on 27 January 2021.
Lore
- Despite being a radioactive arachnid, you will not get powers if she bites you. WARNING: She may bite you.
Likes and dislikes
- She loves stingrays, to the point of having a ray keycap on her keyboard and multiple plushies.
Miscellaneous
- Though tall, she's thin enough that she has previously entered a house through a dog door.
- While collabing with her friend, she was previously mistaken for a text to speech bot... on her own channel. The incident even got its own Know Your Meme article.
- She has multiple designs featuring sunflowers due to them being used to reduce radioactive element pollution IRL.
- She is, notably, not Italian.
- She shares the same character illustrator as Chokico and Salamimeats.
