Nene has a very mysterious personality when first revealed. She has a strong habit of spying on people to gain information (which she does frequently before joining the Fusion Fighters). She is willing to do anything in order to obey AxeKnightmon's orders, going as far as to torture Stingmon for information or threaten Christopher so that he'll join up with them. After joining the Fusion Fighters, Nene became friendlier and more compassionate.
