"People don't understand the word ruthless. They think it means 'mean.' It's not about being mean. It's about seeing the bright, clear line that leads from A to B. The line that goes from motive to means. Beginning to end. It's about seeing that bright, clear line and not caring about anything but the beautiful fact that you can see the solution. Not caring about anything else but the perfection of it."
The Andalites are an alien race of grazers. They are centaur-like creatures, with the lower body similar to a deer and a torso similar to a human. The males' entire body is covered in blue fur and the females' in bluish-purple fur, which becomes tan-coloured as they get older. Their arms, somewhat weak in comparison to that of a human's, end in seven-fingered hands, which while weaker, they are nimbler as well. The head of an Andalite has a set of almond-shaped eyes, as well as a pair of stalk-eyes that endow them with 360-degree vision. They have a nose-like organ which features three vertical slits. Their sense of sight is similar to that of a human's, though the stalk eyes can see a small ways more into the ultraviolet spectrum and the infrared spectrum. The other most notable feature of the face is the lack of a mouth. They eat by crushing grass under their hooves and absorbing the nutrients. They communicate by way of telepathic communication, called Thought-speak.
