Cynthia Shirona

Cynthia is the Champion of the Sinnoh region, who makes her first appearance in Pokémon Diamond and Pearl. She also is the first female, non-playable character Champion introduced in the core series. Cynthia is an archeologist who investigates myths involving Pokémon and is described as mysterious, referring to herself as "the researcher of myths." With her interest in mythology and history, she spends her time researching and exploring various sites associated with Legendary Pokémon of the Sinnoh region. Because of this Cynthia has a wide knowledge of Pokémon and their relationships with people, creating some theories of her own. She can get carried away with these topics, often talking for long periods of time or theorizing in places where she shouldn't be. Cynthia realizes this behavior, catching herself and apologizing whenever it happens. Similarly, she speaks politely, frequently asking the player if they are doing well and uses phrases such as "pardon".

Cynthia tends to enjoy relaxation and travel, visiting the villas owned by Caitlin and the player found in Unova and in Sinnoh's Battle Zone respectively. In Platinum, she expresses that part of the reason for this is that she is typically a messy person and has research papers thrown around the house. Cynthia also enjoys the piano, claiming that she enjoys the sound, listening to it with both her body and spirit.

Cynthia has a large love and passion for Pokémon and is implied to have helped Professor Rowan with his Pokédex, embarking on an adventure as a child, similar to that of the player. Cynthia can be seen as a generous person, providing the player with multiple items and information throughout their journey, including Pokémon Eggs. While generous, she is also very appreciative of the player's efforts. At the Pokémon League, she acknowledges the player's strength as a Trainer and their bond with Pokémon. She enjoys fun and challenging battles and isn't easy to give up.

Cynthia's known relatives include her grandmother, her grandfather, and a younger sister, all of which go unnamed. Her family lives in Celestic Town, although her own hometown was not mentioned, even going as far to say that her home region is a secret. Cynthia bears a striking resemblance to Volo and Cogita, implying some form of ancestry, however the direct correlation between the three, is unknown.

Cynthia is an adult woman with long curly platinum blonde hair that reaches behind her knees. Bangs fall over her left eye, and two large side curls fall in front of her shoulders, curling inward, covering her ears and the back of the neck. She has thin eyebrows. Cynthia's eyes are thin, but round, and point outward ending with thick eyelashes. She has gray irises. While their relation is unknown, she carries similar design attributes with that of Volo and Cogita, possessing similar facial structures and colors.

Her hair has four decorations, two on each side of her head, resembling black teardrops, like the Aura-sensing appendages of a Lucario, with a gold stripe around each, as on the ears of an Umbreon. One of Cynthia's most iconic attributes is her long and heavy black coat that drapes over half-way down her legs, ending in dark black fur trim. The coat forms a V-neck with the openings connecting to another with another teardrop-like ornament that is silver in color, potentially acting as a zipper, that ends on the front of her chest. Two more silvery buttons appear next to this ornament. The coat's long sleeves end at her wrists also ending in dark black fur trim. Cynthia also owns a scarf of the same black fluffy material as the fur trim on her coat, covering a majority of her neck. Underneath, Cynthia wears a plain, dark-gray V-neck dress shirt with long sleeves ending at around her hips. Cynthia's long light gray dress pants also lack much detail other than seams. The pants however, do cover her ankles, leaving no form of skin in sight. The toe tips of Cynthia's black pointed high-heel shoes have a thin gold stripe that end at the soles. A majority of her shoes are covered by her pant legs. Cynthia without her coat and hair decorations is seen in concept art for Diamond and Pearl.

Cynthia owns a Pokédex and she has a Key Stone.
