Star Fox Zero has a side mission that can be accessed in Titania after obtaining the Landmaster's Flight upgrade. In this mission, you play as Peppy Hare, facing off against the Salvadora alone. Notably, in the Western version of the game, every time Peppy performs a barrel roll, he shouts "barrel roll!". This is obviously a reference to his iconic line from Star Fox 64, "Do a barrel roll!" that has become an infamous internet meme over the years. However, in the Japanese version of Zero, Peppy remains silent even when barrel rolling, because "Do a barrel roll!" was never in the Japanese version of Star Fox 64 and as such never really became a meme in Japan.
