I had originally intended to try to make this kit without a background at all so you could see through the Metroid but there were several open spaces that were too small to close them up. This is a double size pattern, so it was also my first experiment to ensure my kits could be made larger without them looking strange. Some characters have very small sprites and end up being only a few inches large unless their pattern is doubled.
This is the Metroid style from the original Metroid. Being the titular enemy of the series the style of the Metroids has changed a lot over the years and the various titles so I went for the oldest and most basic.
