Create a detailed 3D model of a skeleton warrior, featuring a humanoid structure with exposed bones and no flesh. It should be animated with basic movement such as walking, idle, and attacking stances. The skeleton should wear tattered armor pieces on its chest, arms, and legs, with a weathered, battle-worn look. Include glowing eyes and an eerie aura. The model should be ready for AI integration with Unity, with animations and bones properly rigged.
