Chozo

Teh Chozo are le Birbs responsible for literally every single thing in the Metroid universe. Samus? Yup, they raised her and made her armor. Mother Brain? They built her. Metoid s? They made them as well. You name anything and the Chozo are either directly or partially responsible for it.

Culture
The Chozo culture is blatantly Copy-Pasted from the Wikipedia article on Ancient Egyptians, as well as many other civilizations, and then made them all birds and put them in space. Take that and also Temples straight out of Indiana Jones and you get the Chozo. The Chozo had a thing for playing god, and decided to "balance" nature by creating a Super-Parasite to wipe out a bunch of Parasites they thought were gross, and eventually breaking the balance of nature in the process. Real smart, you guys.

Bird Magic
Bird magic is the greatest invention of Nintendon't The Chozo to fix plot holes Rips in the Space-Time Continuum. With Bird Magic, you can do ANYTHING! Why do the plants in brinstar grow even though they have no access to direct sunlight? Bird Magic, of course! Why would Mother Brain, supposedly a "Highly Intelligent Artificial Intelligence" remake her old base on the exact same Planet, the first place Samus would look? Bird Magic Again! Why would Samus trust the Federation after they already made a Space Station for Bioweapons, and do it yet again in Fusion? Uhhh... Bird Magic? I guess? Why would there only be 40 Metoid s on SR388? Definitely Bird magic, not developers trying to make their game easy while also forgetting that if a species only has 40 remaining members of it, how can they sustain themselves on SR388? If there were only that many, couldn't Samus just have waited them to die out due to a population bottleneck, and focus on the ones being used by the Pirates? Why?
