After many years of selective breeding, they’ve finally developed a breed of phoenix that, rather than self-immolating itself into ash, instead roasts itself to a perfect internal 165° F while burning off all the feathers, resulting in an instant, ready-to-eat poultry dinner.
It is still reborn from the remains (after you eat it) (phoenomorph)
How is is reborn? Bursting out of your chest? (Sorry, I see “-omorph” and my mind immediately goes to Alien.)
Yep that’s why its name is a portmanteau of Phoenix and Xenomorph
