Mawse Lawson Gouulle is an italian immigrant who was part of an experimental test with a certain chemical that unearthed his animal genes.

His voice should have an italian accent and be necessarily high-pitched (sorta like Super Mario's voice). Also, try to make his growls sound like some sort of animal and, if you want, thrown in an extra word in Italian.

Technically, his voice is high enough for a female to cover the role, but I've never tried anything like that, so I wouldn't know how it'd turn out.
