Bitch in Sheep's Clothing: She comes off as this sometimes. She's usually a sweet girl, but she casually insults Meiko a lot, loves to get passive aggressive with other Vocaloids and is implied to have aspirations of world domination.
Cuddle Bug: Implied in "Crafts", where the Mystical Sock of Wisdom tells her that the best charity she can give is a big hug, to which Miku state that she's "the most charitable person she knows".
Mad Scientist: They love to perform biological experiments on people, including Kaito.
Luka Megurine
The Ace: Parodied, as she's hoisted as a "supreme knower of all things ever" and often gets hyped up by the narrator, when she's actually just a crazy lady who's obsessed with her Trademark Favorite Food.
Establishing Character Moment: "Hello. My name is Cat Orange. But you can call me Cat-O. I like belly rubs because they don't make me explode. Please rub my belly so that I won't explode :3"
Ret-Gone: Possibly, as the storyline he was introduced in was both cancelled and deleted from the channel.
Stuff Blowing Up: Will apparently explode if not given constant belly rubs.
Butleroid
Deal with the Devil: For the low low price of YOUR SOUL you can get a second Butleroid!
