There are many one word names are there. Foreigner, Asia, Queen, Faust, Blur, Genesis,Jet Boston, Cog, Kansas, Caraven, Oasis, Love, Nektar, Pulp, Rush, Smog
I have a few ideas, though you should just name your band what ever you wish. I personally like Objection! , Obliteration! , Massacre! , Harmony, Bewitchment, and Vicariousness.
