Zinnia could be considered one of the most unusual characters in the franchise, mainly because of her depth and her mysterious and tragic history. This has been seen before in characters like N or AZ; however, unlike them, she is unable to achieve a happy ending.

She has a somewhat crazy and overactive imagination, appearing mainly in her pre-battle animation and during her talks with the player character. She is always able to laugh even in sad moments. She can get gassy, strong and stinky.
