Oberon
The Shakespearean character Oberon in A Midsummer Night's Dream is King of the Fairies, but the name, with its strong 'O' beginning, projects a far more virile image than that.
Oberon was also seen as a fairy king in old German legend, in French heroic song, a Ben Jonson masque, and several operas. And an Oberon appeared in Disney's animated film "Gargoyles."
The identically pronounced Auberon is occasionally heard in literary England.

The name of the king of the fairies in Shakespeare's A Midsummer Night's Dream; could work just as well for your little sprite.
