This exciting coloring page shows the huge and intimidating Evil Galactosar from the Monsters vs Aliens franchise. The alien has an intimidating presence with multiple eyes, long teeth and several arms, and it appears to be hovering in space in front of a huge, red planet. To bring out all the details of this alien threat, you can use darker shades of purple for the body, and black for its eyes and teeth. To really make it come alive, use bright blues and yellows for its tentacles, and reds and oranges for the planet. You can create a mysterious and powerful atmosphere by using light blues and grays to shade in the backgrounds.
