Janet (Wander Over Yonder)

Janet is a living sentient planet from the Yonder Galaxy.

Appearance
Her appearance seems to reflect her mood: When she's lonely, she appears to be a baron wasteland. When she's happy, foliage blooms. When sad, she rains. When she's angry, she becomes volcanic.

Abilities
She's shown to have full control of her terrarian, even being able to produce her own sun, since she's not known to orbit a star.

Personality
She's shown to be emotional and obessive. Though she does have common sense, as she came to her sense when almost hurting Wander in an effort to kill Sylvia, which she apologizes for.
