Character mistake: During the events of Angel of the Ring, in several dialogues Ralf, who is a Colonel and is called as such in said dialogues, takes orders from Heidern calling him "Captain." Heidern's correct rank in the storyline is "Commander."
Character mistake: In the "Before battle" segment before battle 5 in Angel of the Ring part I, Kula during her introduction spells at one point "peropero" with an extra p, "peroperop."
Character mistake: In the Countdown to Hope storyline, at the end of the Chapter EX, Ash Crimson tells Elizabeth post stage 5 "I'm sorry, but now I have this power now."
Character mistake: In the first chapter of Night of the Yokai, after saving King and Ryo, Yuri talks to them about Yuri saving King and Ryo. Yes, in third person, which is not a quirk she shows in any other in-game dialogue.
Character mistake: During the trivia quiz in the Christmas event, Chang Koehan calls Shingo Yabuki "Shinho."
Character mistake: In the miniature city background (where you fight the Sentai versions of the Ikari Warriors and many others) a billboard on top of a building has the wrong logo, with "King Of Fighter", instead of FighterS.
Character mistake: In the KoF98 saga, before meeting the Orochi Female team, the protagonist says to Mature "If it's between the Orochis, then you should surrender against Male Orochi Team, then." The repetition of "then" is an obvious mistake, but the meaning of the sentence itself is also inscrutable.
Character mistake: Commenting Kim's team matchup in KoF97, Chris from the New Faces Team says "an ex-convict and a Taekwondo instructor? Sounds like a tough match." He should say "Two ex-convicts", since the team is made of 3 people, with one being Kim (the Taekwondo instructor) and the other two are the criminals Choi and Chang - it is probably a mistranslation.
Character mistake: In "Even if you sigh", part of chapter 7 of KoF97, Choi Bounge says "we really tried to take Master Kim proud", instead of Make.
Character mistake: In KOF, during the first meeting with the Womens' team, Yuri Sakazaki says that Kyokugenryu is undefeated, but even if the protagonist himself did not meet the team, they were part of KOF94 and they lost.
Character mistake: Before the boss fight of chapter 6 in the KOF95 saga, Noah says "Next is the three Kyokugenryu users. Don't let your guard." Down, of course, is missing. Incidentally, the banner in the background has a letter H drawn quite poorly, so it looks like it says "Dunk CMANPIONSHIP."
Character mistake: In KOF 95 section with the protagonist headed towards the Korean team, during the battle with the martial artist the protagonist utters the nonsensical mistranslation; "What's squid sashimi was."
Character mistake: In KOF95, Chapter 3, scenario "Their older sister", the protagonist's box of text says, in reaction to Noah gloating over the supposed cowardice of the "Man with a black mask"; "They're not the eyes of a man who realised concedes defeat."
Character mistake: In KOF 95 1-1, the "man with a staff" speaks to the "man covering his face" and Iori, answering the question "I was called here...but by who?" with a rather questionable "I am called you, Kisaragi."
Character mistake: In the "Before Battle" segment before the fourth stage of Angel in the Ring part I, Angel says about the 'zombie doll' that "it's bad breath puts me in a bad mood", mixing up verb and possessive pronoun.
Character mistake: In the finale of the third part of the collaboration with Street Fighter V, the announcer Serina's sign-off line is "That's all from SERNIA."
Character mistake: In several instances, the objects you get from Summons are mislabelled (for instance, affinity boxes appear as "summon ticket").
Character mistake: In the King of Fighters 2002 chapter, after the defeat of her team, Mai Shiranui (segment "Road to the truth - before battle") shouts "No, Mr. King, I am mad." King is not a 'Mr', it's her fellow teammate and captain of the LADIES team since KoF 1994.
Character mistake: In the "Athena in Wonderland" quest, Episode 2 "Beautiful Cat Fighter?!", Kensou warns Cotton Tail Yuri about "That beautiful clothes" that she is wearing. Should be those, not that.
Character mistake: In KOF 94, Noah mentions before facing the female team that they have many supporters and that it will be like playing an away game, with the crowd in the stadium. The day of the match though, the battle does not take place in any stadium or arena.
Suggested correction: It's a simile. Noah is saying that everyone will be rooting against him.
