Veigar's coat, at least at first glance, is not terribly unique.His base coat is a crisp white, though much of his body is covered in a palette of desaturated browns and tans. The darkest hues can be found at the top of his muzzle and around his face, as well as near his shoulders and down his back, and flecks of brown can be seen throughout the white sections of his coat.

His eyes are a pale yellow, appearing almost white in direct sunlight. Nothing about his eyes will seem unusual until he reaches a year or so of age, when they will become hazy as his sight unfortunately begins to fade. This eerie feature will not be the most noteworthy aspect of his appearance though, even if it will give him an unsettling look as he grows older.

What is most prominent about Veigar is the flecks of white fur that can be found from his face, to his shoulders and sides, right down to his tail - though they generally seem like normal fur, under dim lights they are actually luminescent. In darkness the glow is constant even when faint, though in bright light they are only noticeable when his emotions are running high; they directly correlate to his emotional states.

Since the Ooze event, Veigar's saliva glows a faint shade of neon green.

As a child Veigar will largely be a blank slate, open to be molded by life experiences. Generally he will take after his mother, being far from shy. He will be energetic and curious, his interest hopping from one object to the next with little pause. While his childhood energy might be initially excused as a byproduct of his youth, as he grows older it will become clear that he won't outgrow his bouts of mania. Along with this, he will be extremely emotional, and his will find it difficult to contain how he feels, no matter whether his emotions are negative or positive ones.

Strangely enough, perhaps due to not having concrete parental figures, Veigar will be easily influenced. He will struggle from an early age with who he is and what he stands for, and anything that makes him feel included and important will catch his interest. Once he does latch onto something however he will be passionate about that thing, and often annoyingly headstrong and unyielding in what he stands for.
