Super Smash Bros. Ultimate is the sixth and latest installment of the Super Smash Bros. series. It was first announced during a Nintendo Direct on March 8th, 2018, before being fully shown off at E3 that year.

Connection to the SNK fighting series
Terry Bogard was announced to be the fifth DLC character and the fourth character in the Fighters Pass in a Nintendo Direct on September 4th, 2019, and confirmed for a November 2019 release. Terry wears his well-known second outfit that debuted in Fatal Fury 2, but with The King of Fighters 2000 default color tones, while his animations appear to be modeled after The King of Fighters XII onwards. He is seen being able to use moves such as Power Wave and Burn Knuckle. He comes with his own stage named "King of Fighters Stadium", with Ryo Sakazaki being visible in the background.

In addition to Terry, the Mii Fighter got three new skins based on Nakoruru, Ryo Sakazaki and Iori Yagami. The DLC pack also comes with 50 music tracks, including tunes from the Fatal Fury series, Art of Fighting series, The King of Fighters series, Metal Slug series and Samurai Shodown series, as well as a few select tracks from Alpha Mission, Athena and Psycho Soldier.

Trivia

 * Terry's reveal trailer makes several references to other SNK titles:
 * The beginning of the trailer shows an invitation falling into Kyo Kusanagi's hand, a scene taken directly from the opening of The King of Fighters '94, the message ending with [S] is a reference to Rugal Bernstein ending the message with his initial [R].
 * Ryo Sakazaki's cut-in is a sequence taken from The King of Fighters '96 intro.
 * Joe Higashi and Andy Bogard's appearance features a sequence from Fatal Fury Special.
 * Geese Howard falling from his tower references Geese's demise at the end of Fatal Fury: King of Fighters.
 * Nakoruru's sequence is from the Vs. screen of Samurai Shodown II.
 * Iori Yagami's sequence is taken directly from The King of Fighters '95, complete with his laughter from his signature win pose.
 * Terry's hand that grabs the invitation is taken from his ending of Real Bout Fatal Fury.

 * Terry's inclusion in the game marks the second time Capcom, SNK, and Square Enix (and, more specifically, Street Fighter, Fatal Fury, and Final Fantasy) have crossed over in a fighting game developed by Bandai Namco, as Akuma, Geese, and Noctis previously crossed over in Tekken 7.
 * SSB Ultimate also marks the second game to initiate the clashing return between SNK and Capcom, many years after the SNK vs. Capcom crossover series, with the first game being Tekken 7 as already mentioned above.
