Lich

Trivia

 * Lich's voice actor, Gary Schwartz, voiced the Heavy and Demoman classes in Team Fortress 2, another title by Valve
 * Lich's lines, "UM NUM NUM" and "I'll put his soul to use" refer to lines said by the Heavy class in Team Fortress 2: the first is an alternate to "OM NOM NOM", used when the Sandvich Edible Device is consumed; and the latter refers, in pronounciation, to the voice command "Put dispenser here" (due to Heavy's accent, this line sounds like "Pootis penser here"), which gained notoriety after players started to spam the voice command
