The hero's M-404 PI from 'Revenge of the Yolk' with 'The Next Wave' background.
Famous pilot and protector of Earth
In the first game, the Chickens attempt to conquer and invade Earth. The Hero witnesses this and drives the chickens away. He attempts to eat later, but the Chickens come back with another plan almost instantly.
His spaceship back then used the rear weapon pods as its exhausts. The available colors for the engine were red and blue. The ship also uses a green version of the Ion Blaster as its default weapon.
The Next Wave
In this game, the hero repels the second attack of the Chickens and confronts the Mother Hen Ship. The Mother-Hen Ship manages to escape twice, but on the third encounter, the Hero removes its eggshell barrier and destroys it, securing Earth's safety again.
The design of the spaceship isn't too different from the one seen in the first Chicken Invaders, except for that now the entire M-404 PI is darker with a dark gray tip and dark gray tips on the tail wing, and that the windshield of the spacecraft is now orange instead of blue. The ship also now uses the red Ion Blaster as its default weapon. The side view render of the ship uses a brighter paintjob.
The artwork for the logo uses the design from Revenge of the Yolk.
Revenge of the Yolk
The third game involves the Chickens creating a weapon of mass destruction known as The Yolk-Star™. After going through the entire galaxy, the hero manages to return to the Solar System and destroys it.
In this game, the spaceship's design has been changed completely. Instead of using the rear weapon pods as exhausts, the M-404 PI uses a single triple-exhaust built into the back of the ship, which can move it across thousands of light years very quickly. The tail wing extends out further, the windshield is now red, the area behind it is wider, and the spaceship has some blue markings painted on it around the windshield and in the pods. The available colors for the engine are orange, blue, green and violet.
The fourth game again has the Chickens trying to destroy Earth. This time, they built a machine called the Egg Cannon (a.k.a. the Vitelline Molecular Propulsor, as mentioned by Hen Solo). However, after the hero goes through several portals and explores many galaxies different from his own, he manages to get back to the Solar System just in time and destroys the Egg Cannon.
This game didn't change the Hero's M-404 PI a whole lot. The windshield is now purple, the weapon pods and the tail wing are more detailed, the markings it had earlier are now gray, and it uses the Boron Railgun as its default weapon.
This game also is the only one to allow you to control a different ship. Once you spend 1000 Keys, you're able to play in Hen Solo's Millenium Hatchling. The only visible difference it has on weapons is that it makes your starting Boron Railgun orange.
Cluck of the Dark Side
In this game, a chicken-built spacecraft known as the CK-01 Henterprise spews feathers near the Sun that block sunlight from reaching Earth to freeze it over. Luckily, the Hero manages to blow the feathers away using the Humanity's Greatest Fan, and later destroys the Henterprise.
This game saw a lot of changes done to the hero's ship. The most important change that happened in this game is that the M-404 PI's design can now be customized. As for the default ship setup, the tip of the ship is no longer darker again, however the entire ship is as dark as it was back in The Next Wave. It has some blue markings on it near the cockpit, on the tip, and on the tail wing. The windshield has also a yellowish color. The engine is blue on default settings.
