He just hovers. Without really moving his head. His arms barely move too.
Then i guess there is an entire species of Samuses, with power suits and everything...or something really f***** up beyond what human's mind can comprehend.
Obviously Anthony is the biggest threat in that situation if you didn't saw what Samus can do. He is the biggest and bulkiest of the group and has a giant gun. But Ridley waited for Samus to arrive instead of joining those creatures and enjoying that.
Ridley is obviously not a dragon. He just looks like something between a dragon and a pterosaurus and that something didn't ate anything for at least 1 year.
He is still intelligent enough to at least be unique compared to other bosses and enemies. I already made a post that explains why Roidley is not just a mindless beast.
And if he would be just an animal, then he would never trick those scientists into entering his cage so he could kill them and escape. He could have remained in that cage since they were feeding him and he was just kinda like a pet.
OR he just can change color like an chameleon, but a lot better (he can turn invisible). Like chameleons in fiction. He turns dark-grey in Other M when his skin becomes invincible to Plasma Beam. Also, in ZM, Ridley wasn't black. I don't know how this color is called, but it isn't black.
- He died on Zebes and there was absolutely NO SPACE PIRATES on SR-388.
- It is officialy confirmed or at least it is canonical, i don't remember, that Ridley is dead. And his clone. And that clone's X-parasite mimic. It doesn't means he will never return because there is still Space Pirates somewhere and they (and maybe Galactic Federation) would most likely store Ridley's DNA (and Kraid's since he somehow returned in SM after Samus killed him in ZM) just in case something like that happens. Or, you know, Metroid will not get Fusion sequel and will, just like LoZ, get only prequels, sequels of prequels, prequels or prequels, etc. Then we could get explanation why exactly Ridley is suddenly organic in SM.
Ridley survived events of Super Metroid only in that non-canonical SM comic. He escaped Zebes before even encountering Samus for 2nd time.
I noticed something about Galactic Federation - there is no other specieses shown except for humans and maybe Chozo and Luminoth. At least in the games. That is weird since there is supposed to be a lot of them...
