The Pokemon Company International is kicking off its celebration of the "Pokemon" games' 20th anniversary with a costly commercial in Super Bowl 50.

The spot will encourage fans to "train on," the company said. In the video games and trading card games, fans "train" their "Pokemon" characters for battle. Pokemon is working with the agency Omelet on the commercial.

As part of the campaign, the company is also using the hashtag #Pokemon20 for fans to share their favorite Pokemon memories on social media.

The company declined to reveal other details about the commercial, including its length or during which quarter it will air.

"Pokemon" was first introduced in Japan in 1996 with the video games "Pokemon Red" and "Pokemon Green" for Nintendo's Game Boy.

Video games have a growing history in the Super Bowl, from the "Dante's Inferno" console game spot in the 2010 game to last year's ads for the mobile app games "Hero's Charge" and Game of War."

CBS is selling commercials in Super Bowl 50 for an average of $5 million.
