“The invasion of Katina is a textbook example of a Venom assault. The first enemy objective is to establish air superiority. Since Andross's Invader IIs are inferior to Cornerian fighters, the enemy will overwhelm the defenders with huge numbers. As Saucerer flies over primary targets, air defence units are lured into meeting the first wave of Invader IIs. A larger wave of enemy fighters then swarms out of Saucerer and eliminates the preoccupied defenders. With the skies clear, Saucerer deploys its Core Weapon and commences with the second objective: the complete annihilation of hapless ground units. At the end of the battle, shock troops are dropped to enslave any survivors.”
—Lylat Datalink; Anatomy of an invasion, pg 68
The Cornerian Fighter was the backbone fighter aircraft in the Cornerian Army during the Lylat Wars, often deployed by carrier or surface base. They are often seen on most Cornerian bases and fleets, such as Katina for example. It was multi-purpose fighter designed for many different types of missions like steath or assault, and is customizable based on the users strengths/weaknesses.
During the Lylat Wars, weak versions of these fighters were produced en masse at an astonishing rate to combat the massive numbers of the Androssian Army. It was the easiest to pilot for untrained cadets, and thus the most used fighter at the time. With its modest shielding, armor, and performance, it could can stand toe-toe against nearly all threats before the invasion by Andross. The Invader II Assault Fighters suffered from numerous design flaws and were vastly inferior to Cornerian Fighters. To overcome their shortcomings, Andross had ordered all Invader IIs to be painted with Cornerians markings to confuse the Star Fox Team's target priorities, nearly managing to fool all but the advanced Targeting Computer. The beleaguered Cornerian Defense Force was nearly exhausted from holding back wave after wave of enemy fighters.

Bill Grey's Cornerian Fighter in the 3DS release of Star Fox 64 resembles the one used by him in Star Fox Command. This was presumably chosen to tell him apart even more.
The Cornerian Fighters piloted by Krystal and Bill Grey in Star Fox Command also bear a slight resemblance to the Guardian Mantis piloted by Vana Sage in Star Wars: Starfighter, except the Cornerian Fighters have pointed noses while the Guardian Mantis has no nose at all.
Interestingly, Bill Grey's fighter in Star Fox Zero resembles the Wolfen in design.
