Most notable in Dizzy are her wings, Necro (right) and Undine (left), which are her "systems", and her reptilian, salamander-like tail. The two wings attack and defend alternately, morphing into different forms and acting separately. In some instances, they transform Dizzy's body parts like her arm and her tail. Occasionally, Necro transforms her into a demonic figure. In the memorial book, an early drawing of Dizzy shows her with dragon wings.

With a 3-year existence with most of it spent in a small village and a grove, Dizzy's experience is very limited. She's very gentle, innocent, pure-hearted, and kind to anybody she encounters. However, her immense power and her lack of control of it only causes her grief, as she sees it as a curse. She hates violence with a passion and fears to hurt others, thus she isolated herself. This only caused her more sadness, as she constantly longed for human contact. When she got adopted by the Jellyfish, she found her family and happiness. In the subsequent games, she willingly fights to protect her friends.

Dizzy has a hidden realistic side though, as she views the destruction of nature by humans as part of a natural cycle. It is also stated that she is ravenous for knowledge and is excellent in gathering data, evidenced by the number of artwork with Dizzy in a library or holding a book.
