Xylene

From Wikitrix

Xylene is an alien friend, colleague and potentially former lover of Max's that came to Earth to retrieve the Omnitrix in "The Visitor". She possesses powerful telekinetic abilities, allowing her to move objects with her mind and fly. Xylene was the one who sent the Omnitrix to Earth in the first place, and that she had intended to send it to Max. Because Ben found the device instead of his grandfather, she said that the capsule had veered off course,. She also accessed the Upchuck form on the Omnitrix for Ben, showing high knowledge of its workings. Being reptilian, she doesn't truly understand things like familial relationships ("On my planet, once you hatch, you're on your own.") and seems to view Ben and Gwen as rivals for Max's affection rather than family members.
