It appears that Nintendo may have accidentally let slip new information about an upcoming Super Smash Bros. Ultimate DLC character. In a listing on Nintendo of UK's official website, Challenger Pack 4 was shown to feature "1 new fighter," "1 new stage," and "several new music tracks." The listing doesn't specifically identify the character, but below the description, there is a copyright notation reading, "©SNK CORPORATION ALL RIGHTS RESERVED, " suggesting the next Super Smash Bros. Ultimate DLC character could be coming from SNK.
This bit of news is especially surprising because rumors regarding Super Smash Bros. Ultimate's next DLC character have been blazing. There have been rumors about Ninja Gaiden's Ryu Hayabusa, about Untertale's protagonist Frisk, and about Overwatch's Tracer and D.Va, and those rumors are all from just the last week. Yet, there have been no rumors regarding any SNK characters in recent memory.
As to which SNK character Nintendo could put into Super Smash Bros. Ultimate, there are so many possibilities. SNK is known for franchises including King of Fighters, Metal Slug, Samurai Shodown, and Fatal Fury. The pony-tailed Terry Bogarde is by far SNK's most popular character, though Geese Howard is gaining due to his inclusion in Tekken 7. SNK's most popular female characters, Nakoruru and Mai Shiranui, would also be great picks.
Recent rumors may not deserve much faith given this new SNK curveball, but even the more ambiguous rumors have pointed toward the addition of a female character. Kazooie is brilliant, but a female DLC character would pair nicely with the otherwise all-male DLC cast, especially so since Dragon Quest's The Hero specifically went with all of the character's male variants.
Before this rumor gets labeled as confirmed, there is one detail worth noting. The Nintendo of UK website has a similar listing for SNK Heroines' next DLC for the Nintendo Switch. "New Character MissX" also has the SNK Corporation copyright notation. This could mean that whoever was putting together these listings accidentally copy and pasted the copyright to both, an accident that seems plausible.
Expect clarification from either Nintendo or SNK in the near future.
Super Smash Bros. Ultimate is available now exclusively on Nintendo Switch.
