Simon Smoke is an anthropomorphic dragon, characterized by light reddish-orange scales that complement his long reptilian tail, thin eyebrows, and expressive black eyes, which have triangular eyelashes and (like the other Nightmare Critters) are furrowed into a permanent glare. His features extend to white wing membranes, an underbelly, and ears (the insides of which are white), while a touch of crimson red graces his talons, mane, and wing bones. He houses yellow tail spikes and two curved horns, and he wears a yellow rectangular earring on his left ear. In line with the other Nightmare Critters (and the Smiling Critters), Simon sports a perpetual wide grin with a darkened inner mouth but possesses four white fangs on either side of his mouth. A black necklace gracefully adorns his center, showcasing a captivating yellow dollar sign pendant. Simon also emits the scent of wood smoke from the little spray applicator in his mouth. Personality Simon Smoke knows he's cool and popular, and he makes sure nobody ever forgets it. Whether showing off for friends or just bragging about one of his accomplishments, it's always a popularity contest with him. Almost always, he wins. In truth, he is a colossal jerk, but he does have a knack for getting away with being one. According to his character description, Simon Smoke is the popular kid of the Nightmare Critters. An egotistical, pompous individual, Simon frequently gloats about his numerous accomplishments or shows off to his friends. Staying popular and being number 1 in everything is what motivates and drives him in life. Rarely are his accomplishments matched or surpassed by anyone else's, further inflating his ego. It is this popularity that keeps the other Critters from discovering the truth: Simon is nothing more than a monstrous bully.
