Asteroid Manipulating Chicken will appear covered with asteroid shield (that will look best if 2.5D could be implemented, especially for spherical asteroid movement).
In phase 1, it’ll have one shield layer of small asteroids, will shoot eggs (in CI2’s Big Chicken’s rate), and will sometimes cause a shockwave firing remaining asteroids from the shield. That chicken can quickly regain a shield by manipulating powers to protect itself.
When it lost 33% of its total health, phase 2 begins. It’ll cause a shockwave first, then it’ll gain new shield layers (first outside one is the same as in phase 1; the second one is filled with medium asteroids). Instead of shooting eggs, it’ll now use its manipulative powers to send a asteroid wave (if you remember original Chicken Invaders 2, there were background asteroids and that was inspiration for this attack) to us.
When it lost 67% of its total health, (final) phase 3 begins. As in phase 2, it’ll cause a shockwave first and then it’ll gain new shield layers (outside and middle ones and the inside one made from big asteroids). It’ll do shockwaves more often than before and it’ll use its manipulative powers to send a wave of asteroids to us and throw huge asteroids at you.
