Musrex is a mashup of the latin words for mouse and king. The name is a play on the folklore of rat kings, bad omens associated with plagues. As an immigrant, Leandro identifies with rodents – unloved creatures with no permission to exist, but nevertheless survive and thrive.

Leandro chose mouse king (Musrex) as opposed to rat king because mice are cuter, but also because he strives to be bold and playful with his work.
