She the unseen Bigger Bad of that foresaid episode, since she's the one who sent the space bug to Earth, and was responsible for the events of the episode.

In Danger & Thunder, she makes a physical appearance and attended the secret villain meeting, and it is revealed that the space bug belongs to her, revealing herself to be responsible for the events of the space bug incident. It is unknown what kind of powers she may possess but we can speculate them to be the same (or similar) to the Space Bug.
