DreamMix TV: World Fighters Unlockables (PS2)

DreamMix TV World Fighters is a 2003 multiplayer fighting game for the GameCube and PlayStation 2. It features licensed characters from a few well-known Japanese companies, including Konami, Hudson Soft, and Takara. A fledgling television program has been suffering from poor audience approval, and the station that carries the show has informed its producers that they will have to rectify the situation or face inevitable cancellation.

An unorthodox plan is implemented: broadcast a contest pitting various superstars from different realities in physical combat in order to increase ratings. Up to four gamers can choose from seventeen playable characters, each with their own themed backdrop, from video game and toy series such as Castlevania, Metal Gear, Gradius, Bomberman, Adventure Island, Bloody Roar, Transformers, Beyblade, and Micronauts. Here's a list of unlockables for the fans of the game:
