I have info for Dani posted on my deviantart. I'll just sum some of it up because I don't feel like making a character profile right now.
Gender: None (Agender)
Social life: Not many friends, very clingy and worries about friends often. They're always afraid they're going to loose them. A very loyal and trustworthy friend, but very sensitive.
Voice: Chuggaaconroy. Chugga is the voice actor.
Powers: Can levitate, but other powers are unknown since they don't use them often.
