Mask sees no joy in life and thinks anyone who is happy should be stomped out. He hates Inklings who enjoy life, and he despises optimism. He's confident, clever, and knows how to take down a team without even breaking a sweat. His voice is raspy, whispery, and low, but not very deep. He isn't very emotional, but once he gets angry, it becomes obvious. He’s also a highly skilled fighter, as a member of the S4.
