Road Attack Zord (as named by Gemma) is the Ranger Operators' wheel-like robot, described by Flynn as a "self-deploying combat weapon" and by Doctor K as a "self-operating ". When the Engine Cell Chip is set in its palm-sized "Wheel Mode" form, it enlarges and transforms into a Megazord-like "Warrior Mode". With the Engine Cells used for the other it can transform into human-sized wheel or warrior modes, and with its own personal Engine Cell, it transforms into the wheel or warrior forms enlarged in-scale to the size of the Rangers' Megazord formations.Not So Simple
