Most asura have double consonants. Vekk, Sokka, Jezza, Oggy, Zojja, Florggi, Snaff
Is the basic naming convention. So I'd try Greerr, Uzzo, Shirr, Nivva, Grezza are all derivations of your listed names that follow "convention" (I apparently should've gone with Oukk since it's a male toon...)An asura's name often consists of a short, sharp first name with one or two syllables. Feminine asura names typically end in -i or -a vowel sounds, but are not required to do so. Masculine names often end in a consonant sound. Both male and female Asuras often have two of the same letter in a row somewhere in their name, this being a cultural norm, but it is certainly not required. Asura do not have a last name, instead opting to use job titles, a krewe name, or honorifics to differentiate themselves. Those who choose to take a last name of a style similar to humans are rare and are considered eccentrics, though their surname is often ignored by other asura.
