Create a superhero inspired by Thanatos, the Greek god of peaceful death. Reimagine him as a modern end-of-life caregiver, ensuring serene transitions in a high-tech age. His attire should be a blend of medical wear and futuristic fabrics, adorned with symbols of rest and passage. Eyes should convey deep empathy and acceptance. Accessories might include a touchpad that eases pain or a pendant that captures final memories. Embrace a palette of soothing lavenders, clinical whites, and twilight blues. Capture the essence of a guardian who ensures every ending is met with dignity and care.
