F-Zero series

Cameos of the F-Zero Series in the Star Fox Series

In one of the endings of Star Fox Command, Fox McCloud and Falco Lombardi become pilots in the G-Zero grand prix, a grand prix not unlike the F-Zero grand prix.
In another ending of Star Fox Command, Falco becomes a member of the future Star Fox team where he is paralyzed in the legs. His new boots resemble that of Captain Falcon's, a racer in F-Zero.
Octoman, an enemy in Star Fox Command is also a pilot in F-Zero. His appearance is shared in that game.

James McCloud, a racer in F-Zero bears many resemblances to the character of the same name in Star Fox. Both run a band of mercenaries, his being Galaxy Dog. His appearance is strikingly similar as well, mainly his clothing choice, though. He has a wife and young son, the latter of which he claims he will purchase an F-Zero machine for to get him into piloting. In F-Zero X, his winning phrase is "I am like a sly fox" referencing the Star Fox series.
Leon is named after a Star Fox character of the same name and is based on Wolf O'Donnell.
A large majority of machines in F-Zero use G-Diffuser systems in their engines. The same are used in Arwings.
Space Dynamics Co., the team that developed the Great Fox and Arwing, developed a large portion of the Machines used in the F-Zero grand prix.
