Samus with bed head brushing her and the Metroid's teeth is so disgustingly adorable, I'm tempted to add this picture to that pool on that merit alone.

Samus chatting with Dark Samus cracked me up

It always amuses me when artists depict suitless Dark Samus in a slice-of-life way as a mirror of Samus herself. So rare.

Samus doing average, mundane things is the best. It's been done before, but it never gets old. There's just something amazing about seeing the greatest warrior in the galaxy doing laundry or brushing her teeth.
