I think Samus wearing the Power Suit made by the Chozo who also infused her with their blood, has a strong connection that makes it like a second skin, which allows her to have all the abilities she has with it.
Well when the suit can come off but she dies when it does, or something.
Samus takes off the suit at the end of Metroid 1, II, 3, and 4 for the best ending. The suit comes off when she dies in Super Metroid and Metroid Fusion because, she dies, the suit has lost all its energy to protect her.
Yeah, and it blows off of her. If you aren't good at Metroid games the only time you will see her without a suit is when you die, or you could lok up ending screenshots on the internet.
