Star Fox character designer Takaya Imamura illustrated the back boxart of Star Fox Adventures for its Japanese release. Notably, it's one of the first notable instances of Fox's head being drawn with a more stylized, Noh Kitstune mask look, as opposed to the more animalistic proportions he had in-game and also in prior installments such as Star Fox on SNES and Star Fox 64. This design has often been described by certain fans, often in a derogatory manner, as a "bellhead", due to it being somewhat shaped like a bell.

Star Fox Command would be the first time Fox would sport this head design in-game, and it would go on to influence his appearances in later Super Smash Bros. games and to a certain extent, Star Fox Zero.
