Clean flat-colour cartoon, bold dark outlines, simple cel shading with one shadow tone, slightly retro sci-fi palette of greens, purples and silvers. The attached base image is the base character. Draw 3 legendary one-of-one versions: complete 1024x1024 images with an opaque background, same character and style, each a unique full concept.

Keep EXACTLY the base's framing, pose and placement (facing straight at the viewer, both eyes level and looking at the viewer, head centred left to right; framed head and shoulders: the top of the head near y=210, the neck meeting the shoulders near y=740, both shoulders and the upper chest in the picture and running off the bottom edge; the arms are down and out of view, nothing in front of the chest; extra detail from the creator: looking straight at the viewer, calm and curious), head at the same size and position, so they sit in the grid with every other piece. golden alien emperor, alien in a full astronaut suit, glitching hologram alien.
