Starting Prologue: World of Chaos and Chapter XVI: Sovereign Power while wearing the Star Mercenary costume, which resembles Fox McCloud from the Star Fox series, will turn Jeanne's jet plane into an Arwing. Wearing the costume during the former chapter will feature Jeanne wearing it as well, with a swapped color palette from green to orange. Wearing it during the latter chapter on top of turning the jet into an Arwing will replace the jet's reticle, weapons and sound effects with those from the Star Fox series including being able to fire Smart Bombs, charged shots, and replacing its Umbra Climax with the Hyper Laser. The cutscene at the end of Verse 2 will also switch the receiver sound effect with that of an Arwing's, as well as add three additional Arwings flying behind Jeanne towards Fimbulventr as a nod to the original four-pilot Star Fox team. Additionally, scanning a Fox or Falco amiibo in the Nintendo Switch version will display a message from Rodin implying that Slippy leant the Arwing to Jeanne.
