Cynthia

"To live their lives to the fullest, people and Pokémon need the chance to throw themselves into battle against the fiercest opposition. That's why I want to battle you. How about it?"

- Cynthia

Cynthia is the Champion of the Sinnoh region. She first appears in Pokémon Diamond and Pearl Versions, and is the first female Champion of the Pokémon series. Her name is derived from the word "synthesis," meaning to combine different pieces together, and applies to how Cynthia uses a variety of Pokémon during battle.

Pokémon Diamond and Pearl Versions
In Pokémon Diamond and Pearl Versions, the player character first encounters Cynthia at Eterna City when they first visit the location. She gives them some advice, but leaves shortly after. After Crasher Wake is defeated, Cynthia will be seen at Route 214. She is impressed with the player character's efforts and rewards them with a Secret Potion. Cynthia tells the player to use this on the hoard of Psyduck, who are blocking the entrance to Celestic Town. She asks the player to go to Celestic Town, her home city, and tells the player to go give a gift to her grandmother. After the player does this, Cynthia will appear in the town, and thank the player for delivering the gift to her grandmother. Like most people in Celestic Town, Cynthia is very interested in the mythology behind the Sinnoh Legendary Pokémon. She often travels around Sinnoh to study more on these ancient creatures.

After the Team Galactic dilemma, the player eventually learns that Cynthia is, indeed, the Sinnoh Region Champion. Her abilities as a trainer are shown in this battle. Her Pokémon are all very powerful, all of which are above level 60. However, her powerhouse is Garchomp, which has several powerful attacks that can take away a massive amount of health in one attack. Although, after a long and arduous battle, the player comes out on top, and Cynthia and Professor Rowan deem the player as the new Champion. She can be battled again several times afterwards.

Pokémon anime
In the episode, "Elite Four Goyō and Dōtakun", Cynthia is seen in Lucian's flashback, when he is talking to Ash, Dawn, and Brock about the Sinnoh Elite Four.

In "Enter Champion Shirona!!". Ash and the group were watching a battle between Cynthia and Lucian. Her Garchomp managed to easily defeat Lucian's Bronzong. Ash was determined to battle her. Meanwhile, Team Rocket, who were disguised as Ice Cream salesmen, actually got to meet Cynthia, who actually bought an Ice Cream from them. Ash and the gang then found Cynthia at the nearby ruins, which was just a little walk from Team Rocket's stand. She was studying about the ancient Pokémon Legends. However, when she notices a challenge from Ash's rival, Paul, she decides to battle him. She used her Garchomp, which managed to devastate Paul's Chimchar, Weavile, Murkrow, and Torterra with relative ease. However, Cynthia decided to look after Paul's Pokémon at the Pokémon Center, while at the same time, giving Ash and the gang tips on how to raise Pokémon. After they left the room to go outside for a little while, Team Rocket sneaked into the building and kidnapped Chimchar. However, Paul used his Ursaring to rescue Chimchar, which he then scolded for getting captured. Cynthia, however, cheered the young monkey Pokémon up, and told Paul that he has to show Pokémon compassion and respect. Paul, however, did not seem too interested in this advice. With all this done, Cynthia then decides to head off, and the group wave goodbye, while Paul hopes to get strong enough to defeat her.
