Create a frame-by-frame pixel art animation of the existing spear-wielding warrior. The original sprite’s colors must remain 100% identical across all frames. Do NOT change or modify a single pixel color, shade, hue, brightness, outline color, or contrast. The character’s palette, silhouette, and proportions must stay perfectly consistent. Only the position of the body parts may move. Never recolor or redraw any part of the existing sprite. Animation style: A natural, smooth spear-thrust attack consisting of 6–8 frames. The movement must look physically believable, with proper anticipation, acceleration, and follow-through. Use the character’s current idle pose as the baseline and animate only by shifting limbs and rotating joints. Do not distort or stretch the body, head, legs, arms, or the spear. Keep all outlines and pixel placements consistent except for the parts that need to move for the attack. Motion flow: 1. Small anticipation: the body leans slightly backward. 2. The spear arm pulls back to gather force. 3. Weight shifts forward. 4. A fast, decisive spear thrust forward (maximum extension). 5. Slight recoil after impact. 6. Return smoothly to the original stance. Purple spark effect: Add a small purple spark/electric effect ONLY at the tip of the spear. Spark color must be strictly within a purple palette and must NOT interfere with or change any of the warrior’s original pixels. The spark should intensify during the thrust frame and fade on anticipation and recovery frames. Ensure the effect is visually separate, clean, and does not modify the spear’s base colors. Forbidden actions: - No shading changes - No color shifts (even 1 pixel) - No new highlights or gradients - No outline adjustments except for necessary movement - No anatomy distortion or proportion changes - No inconsistent pixel jitter between frames Final result: A smooth, clean, perfectly color-consistent pixel art stab animation where the character
