Momoka Nishizawa

Momoka Nishizawa is one of the main characters in the series Keroro Gunso. She is the partner of Tamama and is a very rich girl, being the only daughter of the head of the Nishizawa Corporation, Baio Nishizawa. Momoka has short, dark teal/blue hair with two pieces sticking up on each side. They get sharp like blades when her dark personality takes over. She has dark purple eyes. Momoka mostly wears various kinds of dresses or suit tops with mini-skirts. She also sports Chinese dresses a few times. Later in the manga, she also often sports long tight-high socks, but they're much less common in the anime, only appearing when she wears her outfit from the third movie. Momoka used to have long hair when she was younger, and the glimpses of her future self in the anime also show her with long hair again. Momoka has two personalities/alter-egos. Her first and most commonly viewed personality is cute, polite, shy and sweet (taking after her mother's hidden side). In this personality, she acts weak and cannot unleash her true power. Her second is brutal, hot-tempered, and incredibly strong (based on her mother's outwards personality). When phasing to her brutal side, there's a sound similar to that of a sword sharpening or being unsheathed. The four soft spikes on her head then sharpen, and her expression changes. This personality is triggered by feelings of anger and frustration. After an incident where Momoka's dark side split from her temporarily, they even started interacting with each other as completely separate consciousnesses. Sometimes the two sides will work with each other or even in spite of each other, like one time her dark side had a plan to become closer to Fuyuki that was unknown by her main personality. In the anime, a third personality appears once due to a personality transferer device, which applies her father's personality to her. In the manga, using a device to bring out her potential, both of her personalities combined into one while its effects lasted, with dark Momoka's strength and surface Momoka's grace.
