|This article is about a/an villain in Power Rangers Operation Overdrive.|
Crazar is a lynx-like monster who is one of the Fearcats and the only known female member.
Tyzonn informs the team more about the cave-in that occurred many years ago. He tells them that Crazar was also there. He thought Crazar was buried inside because he didn't see her leave with Mig and Cheetar. His girlfriend, Vella, was lost in the cave-in. They were going to get married.
Red Sentinel Ranger and Mercury Ranger take down Crazar. Crazar then makes herself grow. Crazar is disintegrated by the DualDrive Megazord's blast finisher and an old Mercurian battle spell. Crazar was not finished, causing Tyzonn to be knocked unconscious. Tyzonn awakes on his home planet, Mercuria, with his girlfriend, Vella, looking over him. Vella tells Tyzonn that he never left Mercuria. Vella tells Tyzonn that his whole experience on Earth never happened and it's only been three days since the cave-in. Vella says to him that he rushed back in to save her but she escaped, and he was the one who got trapped inside by the Fearcats.
Tyzonn hears a beeping sound near by, then Vella drops something...It's Tyzonn's morpher. Vella then reveals her true form, it's Crazar in disguise. Crazar informs Tyzonn that she had replicated Vella after the cave-in. Tyzonn then learns that Vella is still alive and Crazar is keeping her somewhere.
Tyzonn battles Crazar and learns that he is still on Earth. He kicks into Overdrive and destroys Crazar with his Drive Detector slash wave finisher.
- Crazar bears a slight resemblance to the Dark Predazord of Wild Force, the reason for this is because her Boukenger counterpart, Ouga, as with each primary antagonist and each individual monster of the week was visually designed as an homage to the various robots and other mecha piloted by the protagonists of the 29 previous Super Sentai series (except for J.A.K.Q. Dengekitai), as Boukenger was the 30th anniversary series. Ouga's look was based on Dark Predazord's counterpart, GaoHunter Evil of Hyakujuu Sentai Gaoranger.
- Crazar's Boukenger counterpart is male, making her a part of the somewhat extended list of Power Ranger characters that were gender-swapped from their respective/original Sentai Series, such as Somnibot, Octoplant and Wedding Dress Org. It's most likely because she/he turns into a woman to beguile Tyzonn that Saban opted to change the gender.
- Crazar's head was later recycled for a generic inmate on Sledge's Ship that is first seen in "Rise of a Ranger." It was later seen again in "Forged Under Fire".
- Crazar can be seen as a member of the audience of Galaxy Warriors in Power Rangers Ninja Steel.
