Trivia

• The event icon resembles the game's boxart with more characters.
• This is the only Co-op event to have Jigglypuff, Sheik, and Shulk in it, as they are not played as or fought in any other Co-op events.
  • Likewise, besides the characters mentioned above, this is the only Co-op event to have Diddy Kong, Little Mac, Toon Link, Palutena, Marth, R.O.B., Ness, Villager, Dr. Mario, and Mega Man as opponents.
• After Hungrybox tweeted out a picture of The Ultimate Battle, speculation arose that the event was "teasing" the then-unannounced Super Smash Bros. Ultimate, due to its name, and the event description saying "They're all here!"; however, as the name in Japanese also translates to "The Ultimate Battle", and the name of Ultimate in Japan being Super Smash Bros. Special, the naming connection between the event and the game is purely coincidental.
