Etymology
The name may be a reference to Marlboro Cigarettes, since the creatures often spew horrid fumes from their mouths. The word "mal", originating from Latin, means "bad" or "evil" across many languages, including English, where it is not used on its own but can be found within words such as "malevolent" or "malefic".
