Character mistake: Once the Women's Team wins the tournament and the organizer tells them that he will "stuff them" (awkward...), he concludes proposing "Now, allow me take you to the battle stage", missing "to."
Character mistake: If the Ikari team confronts Rugal, Rugal recognizes Heidern as "the captain of the mercenary SOLIDERS I annihilated"
Character mistake: In the ending of the Korean team, Rugal gets wrong the line he otherwise always delivers correctly before blasting his own aircarrier, and says "A WATRY grave awaits you", instead of "watery."
Character mistake: In the dialogue before the last battle, Rugal answers Andy's "Who the hell are you?" with "I've heard of you often as the world's STRONGERST fighters."
Character mistake: Rugal's comment on the American Sports Team when you reach the mid-game point is that they are diamonds in the rough, and that he looks "FOWARD" to see how far they can get.
Character mistake: In the mid-game cutscene with Rugal observing the progress of the team, if you pick the Fatal Fury team Rugal says "Hmmm. So they are the ones who toppled Geese and Klauser." The name of the villain of Fatal Fury 2 that Rugal is referencing is Wolfgang Krauser, with 2 Rs.
Character mistake: One of Robert's winquotes is "You're just a bunch of fool."
