Platinum Berlitz

Platinum is the female protagonist of the DP series, but she goes by the title Lady Berlitz, and her first name has been kept a secret since the beginning of the series until the story progresses to Canalave City. There were several occasions that her first name has been mentioned, but it has always been covered by other speech bubbles, as if being drowned out by other sounds or voices. This was deliberately done to wait for the release of the third sequel to Pokemon Diamond and Pearl, which title was planned as her first name.

Platinum is a descendant of the prestigious Berlitz family, which is a wealthy clan in Sinnoh with a history of more than 200 years, producing fine scholars in every generation. A family tradition calls for each individual to travel to the summit of Mt. Coronet, and collect a special material to create an accessory bearing the family crest. Like her father Sir Berlitz, she is acquainted with Prof. Rowan and has worked as his assistant before she set out on her journey, allowing her to know a lot about Pokemon.

Proud and arrogant, Platinum comes off as a spoilt girl, and only spends her nights at top-class luxurious hotels. She did not find it necessary to reveal her name to people of a lower class, as taught by her butler Sebastian, and thus refused to tell it to Dia and Pearl, whom she mistook as her bodyguards due to a mutual misunderstanding. However, Platinum actually has the heart of an innocent child underneath her perky exterior, and can sometimes come off as goofy even. As she weathered through various adventures under the support of Dia and Pearl, she gradually came to appreciate their presence, shared her glory of victory with them when she won the Super Contest, and even started addressing them by their first names after the incident at Veilstone City.

When Sir Berlitz became Team Galactic's victim of false ransom, Platinum rushed to Canalave City to find him, during which she discovered the truth about Dia and Pearl's real identities, something the boys have known since meeting the real bodyguards but decided to keep a secret from her for the sake of sustaining the ties they've worked so hard to keep. Platinum took the news hard since she trusted the boys so much, and locked herself behind close doors. After sorting out her thoughts through a fitful night's rest, during which she dreamt of the boys perishing in an explosion, she made up her mind to continue their companionship. She revealed her full name to the boys after confessing her own lies throughout their journey, an act to make them equal as friends instead of the client and bodyguard relationship they've shared so far.
