Meesterious Mia is a white woman with long red hair in a silver one-piece dress, and wears high heels with brown leggings. In Serious Sam HD: The Second Encounter and Serious Sam 3: BFE, she has a two piece dress with cleavage exposed, a tattoo on her right breast, high heels, and sunglasses.
Meesterious Mia is only playable in Serious Sam HD: The Second Encounter if the player has the Serious Eight DLC. If they don't, she cannot be selected in the menu. Since the DLC is currently impossible to obtain, there's no way to play as her if the player doesn't already have it.
Meesterious Mia was born in a small town in Texas. Ever since she was young, she's always been the center of attention, which eventually landed her a career in the entertainment industry. At first, her career went well starring in “Pyramid Raider IV” and as FastFinger Freddie's lover in “Ways of our Wives”, but then Fastfinger Freddie left “Ways of our Wives” and the show was cancelled afterwards. She tried to regain some of her glory by starring in “Bronx 90210” as Nelly, the main woman character, but the show bombed. With her acting career pretty much over, she decided to join Serious Sam and his fight against Mental as her last chance to get some attention.
