Sybe

A high-level magical beast called Psycho Bear. It, along with other Psycho Bears, attacked Barilossa and the others, but all except itself were annihilated by Flio and Fenris. Despite this, it attempted to attack Fenris, but was overwhelmed by her (irritated) intimidation and surrendered. Through a subjugation spell, it was named "Sybe" as a pet of Flio and the others.

Because its form as a Psycho Bear is too large, it usually takes the form of a Unicorn Rabbit through Flio's transformation magic. It can switch between its Psycho Bear form and Unicorn Rabbit form on its own.
