The general reptillian shape is clear in Nihaxu's forward stance, counterbalanced by a tail slightly longer than the robot's height. The tail has a plate arrangement similar to the neck, with the same blue glow. The end of it appears to be entirely glowing blue, but this is an illusion created by the extremely large number of flex points near the end, allowing its tail to be prehensile. The thin, digitrade legs have similar glows at the joints, similar to the joints of the arms. The hands, however, are far more complex than the robot's two-clawed feet, each hand having three strong, opposable fingers.
The body of the robot is nearly unadorned, a small collection of blue lines betraying the presence of motorized pockets it can use to store small objects. Closer inspection of anywhere on the robot would reveal an extremely fine grid of tactile sensors, and this grid would be extremely visible due to its density on its feet, hands, and tail were it not for the blue glow surrounding the area. Nothing in the robot's relatively simple design grants any information about gender or emotion.
