Jikkyou Powerful Pro Yakyuu^[a] and marketed internationally as Power Pros, is a Japanese baseball video game series created by Konami. The game is known for its super deformed characters, and fast-paced, but deep game play.^[2] Most games in the series are developed under license from the Nippon Professional Baseball (NPB) and the Japan Professional Baseball Players Association (JPBPA), letting them use the league’s team names, stadiums, colors, and players’ names and likenesses. There are also six games in the series with the Major League Baseball (MLB) and Major League Baseball Players Association (MLBPA) license, two with the Korea Baseball Organization (KBO) and Korea Professional Baseball Players Association (KPBPA), and one with the World Baseball Classic license. It is long running in Japan, starting out in 1994 for the Super Famicom, and appearing on many different consoles: Saturn (1995–1997), PlayStation (1994–2003), Nintendo 64 (1997–2001), PlayStation 2 (2000–2009), Dreamcast (2000), GameCube (2002–2006), Wii (2007–2009), PlayStation 3 (2010–2016), PlayStation 4 (since 2016) as well as PlayStation Portable (2007–2013) and Vita (2012-2018).

The game has two spin-off series: Professional Baseball Spirits, a baseball sports simulation series with more realistic graphics and physics, and Power Pro Kun Pocket. The latter was released on handheld systems between 1999 and 2014 with versions for the Game Boy Color, Game Boy Advance, and Nintendo DS. Although the series was originally designed as the side-story of Success mode and was part of the main series, Konami retroactively declared it as a separate series.

In Japan, the series has been critically acclaimed and commercially successful, while in North America it received mixed to generally favorable reviews^[4][5] and sold poorly.^[6] As of December 2020, the series has sold over 23.5 million copies, in addition to 44 million mobile game downloads as of October 2020.^[7]
