Since my ideas about Featured Articles seem to have been well-received, I went ahead and created Template:FA for us to put on the talk page of articles we'd like to nominate.
Already nominated Ralok's suggestions (Hokita and Remulakian) plus the following articles: Anunnaki, Cardassian, Dalek, Elder Thing, Felucian, Geth, Grox, Kryptonian, Long One, Mala'kak, Martian (Looney Tunes), Martian (Ray Bradbury), Melmacian, Mesklinite, Metroid, Necromorph, Pak'ma'ra, Prawn, Soft One, Species (Alien Species), Tenctonese, The Thing, Weeping Angel, Xenomorph and Yautja.
These are the wiki's best articles IMO, but if you disagree feel free to contest them. Also, please nominate more articles if I forgot some which also deserve FA status!
