A teflon non stick coating and yes the Covenant breath air except the grunts who breath methane. To be honest its fiction. There are a hundred and one questions that you could ask Bungie and the team would probably come back with 'cos it looks cool' half the time. Granted the story makes Halo enthrawling but it is only fictional.
