Heartless Killing Machine Mug

Start your day with a dose of dry sarcasm and robotic self-loathing—just the way Murderbot would want it. This Murderbot Diaries-inspired mug features the iconic quote: “As a heartless killing machine, I am a terrible failure.” Perfect for fans of The Murderbot Diaries by Martha Wells, this mug captures the reluctant hero's energy—equal parts existential dread, protectiveness, and social anxiety. Whether you’re bingeing media, enduring unnecessary human interaction, or simply trying to survive another meeting, this mug is your ideal companion.

Available in 11oz (standard) or 15oz (large)
Dishwasher and microwave safe
