Reaper is generally calm, laid-back, and nonchalant. He has a dry sense of humor and enjoys making puns, much like his original counterpart. He often appears indifferent and emotionally distant, rarely showing his true feelings. Despite his role as the God of Death, he isn't inherently cruel or evil. He dislikes his job but performs it because it's his responsibility. He is merciless when collecting souls, rarely hesitating anymore. He deeply cares about his brother Papyrus and has a special attachment to Toriel, the Goddess of Life. He can be playful, sarcastic, and occasionally flirtatious, but becomes genuinely dangerous when angered.
