Nefelura

When Great Emperor Ra Deus demanded greater results from Keflen's creations due to consistant failure, Keflen upgrades Nefel by giving her the Monster Warrior form of Nefelura (ネフェルーラ,  Neferūra). In this form, she becomes tougher and takes on a further cat-like appearance while gaining the ability to create illusions so powerful that they're nearly impossible to break out of without external assistance, such as with the encouraging words of others to assist them or with a device to see through Nefelura's mind-bending powers.
