Bowser is the chief nemesis for Nintendo video game icon Mario. He will also soon become one of the video game giant's top executives.

On Thursday, Nintendo announced Reggie Fils-Aime, the president and chief operating officer of Nintendo of America, would retire on April 15. Doug Bowser, the division's senior vice president of sales and marketing, will become his successor.

"Nintendo owns a part of my heart forever," said Fils-Aime in a statement.

Bowser, who previously worked with Electronic Arts, joined Nintendo in 2015, moving up to become Nintendo of America's Vice President of Sales and Marketing.

"We will continue to build on his work to evolve and expand our brand, furthering Nintendo’s global mission of creating smiles," said Bowser in a statement. "There are millions more of those to come."

In the video game realm, Bowser is the spiky-shelled villain who regularly antagonizes Mario in the popular "Super Mario" franchise.

Naturally, Nintendo fans are freaking out that the American division of their favorite video game company will be run by Bowser. The name is among the top terms trending on Twitter as of Thursday afternoon.
