Trivia

 * This is the second largest crossover roster of In-Verse's history, the first being the 10th anniversary game Legends.
 * This is the first In-Verse Heroes game with a proper story, despite being the average crossover type, it will have no talked dialogue except for some scenes like The Subspace Emissary from Super Smash Bros. Brawl, instead, and the rest is text-based.
 * Some of the unorthodox selections, such as Sage, Ike, Echidna, Yuri and Hilda, and clones such as Kali and Ignis, are secret characters.
 * Victoria and Jet Dark are the only main characters from games with more than two representatives that aren't final bosses in their representative franchises. Instead the spot belongs to Solaria and Darkness (the first is Victoria's servant and a major rival to Vlad in DMotNIII, the latter is the antagonist of the Neo Formula Racing expansion Xtra.)
 * The story mode will be shorter than Versus, lasting 7-9-hours, 31-hours less than Versus' 40hrs, and the 50-hour Legends.
 * There's a hint that Lumina and Mercury are secretely engaged, according to future characters such as Devil's Eye party, Sibylla, Balder, Ignis, Battle of Zero reps, the Neo Formula quartet, etc.
 * And that's apparently the reason behind Lumina wearing an eyepatch in this game and in Versus.
 * However, due to their age difference; Mercury is more than hundreds of years old and Lumina is only in her mid twenties, but her real age is unknown. This causes a personal conflict between the two.
