Konami Corporation (コナミ株式会社, Konami kabushikigaisha) is a leading developer and publisher of numerous popular and strong-selling toys, trading cards, anime, tokusatsu, slot machines, arcade cabinets and video games. Konami is famous for many different popular game series, such as Metal Gear, Castlevania, Silent Hill, and Dance Dance Revolution.
In the mid 2010s, controversy during the development of Metal Gear Solid V: The Phantom Pain led to famed developer Hideo Kojima cutting ties with the company and the company itself losing considerable goodwill with fans.
The mascot and most famous character of Konami, Solid Snake, appears as a playable character. In addition, many others from Konami's Metal Gear series, such as Gray Fox, Shadow Moses Island, and Metal Gear REX, appear in Brawl as well. Otacon, Colonel Roy Campbell and Mei Ling also appear in Snake's Smash Taunt in which they talk with Snake about the character he's battling.
After missing out on the previous game, Snake returns as a playable character along with one new music track from Peace Walker and a new Final Smash, Covering Fire. Additionally, Simon and Richter Belmont from the Castlevania series make their debut as playable characters. Other elements from Castlevania appear such as Dracula's Castle as a new stage along with Dracula himself as a boss.
Due to rights issues with Kojima Productions, Snake's symbol is changed from the FOX emblem (which was also Kojima Productions' logo) to the series' signature exclamation point.
