Leaper:
Described as the "power of possibility" as well as the forbidden power to change the laws of the cosmos, Cat Leaper improves the Rebecca's speed and agility drastically to the point where she can become so fast that she leaves behind afterimages to confuse or mislead opponents. However, its true power allows the user to potentially change the outcome of past events by rewinding time.
One of the side effects of its activation, is that Rebecca's footwear ends up getting destroyed as a result of the release of energy. Pushing herself too much with this ability however, will cause an immense amount of pain and even cause her body to start to break down. When time leaping, Rebecca essentially enters a parallel world that may cause a change around her, but history will converge to its predetermined future. She can use Cat Leaper several times, with it even activating if she loses her life, but she would have no recollection of the previous timeline when normally she does.
Overdrive:
By allowing an Ether Gear's power to flow throughout their entire body, an Ether Gear can acquire a massive boost to their capabilities as well as being able to achieve feats with their Ether Gear they normally wouldn't have been able to. Along with this increase in power, Rebecca takes on a new appearance similar to that of a machine's; having three-dimensional lines of Ether surrounding her body and covering their skin as well as getting a pair of cat ears and tail, even her hair changing color.
