|“||I can accept nothing but victory, because I have already pledged the honor of my family name in front of an audience!||”|
–Platinum, Pokémon Adventures: Volume 31
Platinum is a well mannered and elegant member of the Berlitz family. She is often described as a princess and because of her heritage she starts off as rather aloof and refuses to tell her name to "commoners". However, she has made an effort to be less so, even biting back on impulse and telling Buck her name.
Owing to being sheltered for a long time in life, she shows signs of enthusiasm at trying anything new. For instance, her excitement at going down in a coal mine on a tour resulted in her getting attacked by Kricketot. She sometimes has a naivety about the Pokémon world and its customs. In example, she had never heard of Gym Battles or Pokémon Contests until her journey.
She is very knowledgeable since the beginning of her journey, but she's decided that it's better to experience things rather that just reading about them, making her the chosen one of Uxie. Due to her connection with Uxie, she is given the title of "Understander".
Diamond & Pearl arc
Prior to starting her Pokemon journey, Platinum was born into the Berlitz family, well known for their wealth and generations of scholars. Due to this fame, she became well acquainted with Professor Rowan. This led to her possession of the Pokédex and the three Sinnoh starters, which she was meant to provide her bodyguards. The original purpose of her Pokémon journey was to continue the Berlitz family tradition, by traveling to Mt. Coronet and obtaining a specific material used in creating the Berlitz crest.
She didn't know that Diamond and Pearl were her bodyguards and she thought about it when she learned the truth but she still kept the two of them because of their friendship. She is being taught by Diamond and Pearl how to battle.
Whenever she is battling a Gym Leader, Diamond and Pearl give her some tips. She met Cynthia while training for her battle with Gardenia. In later chapters, she swears to defeat Team Galactic's plans and forgives Diamond and Pearl for lying.
Platinum makes another appearance in the Platinum arc. She bought a Villa after Steven Stone sold it before leaving back to Hoenn. Platinum planned to turn it into her Battle Zone base.
