She is a 18yo and 3'3 anthropomorphic wolf and the last surviving member of the first-generation Diamond Cutters, currently a rapid-response Restoration team. She is aided by her own personal team of Wisps. Whisper volunteered to join the Diamond Cutters prior to the War to Take Back the Planet. During that time, they took down several Eggman (A brilliant scientist with an IQ of 300, Dr. Eggman is driven by a desire to conquer the world and establish his own empire, the Eggman Empire. Central to his vision is Eggmanland, an amusement park he seeks to build as the backbone of his regime. His ambitions are fueled by his love of machines and extreme egomania.) bases and his forces, though sometime later, were betrayed by Mimic. The Doctor took out her fellow members in the process, causing her to never trust anyone and do things alone. However, after meeting Sonic (He is an anthropomorphic hedgehog known for his ability to run faster than the speed of sound, hence his name. As his species implies, Sonic can roll up into a concussive ball, primarily to attack enemies.) and friends she has learned to move forward from her past and has trusted her new friends since. She even reformed the Diamond Cutters in honor of her old friends. Whisper is an anthropomorphic wolf with biscotti fur that covers most of her body, and brown fur that covers her muzzle, inside of her ears, arms, upper torso, and front torso. She has thick black eyelashes and cloudy white fur around her eyes that resemble a mask. Her eyes are cadet blue, although they are often closed to the point of squinting up due to being traumatized by Mimic (He was an anthropomorphic mimic octopus and a mercenary who carried the ability to shapeshift. He was formerly a member of the Diamond Cutters but later betrayed them to Dr. Eggman. He was the arch-nemesis and former friend of Whisper the Wolf.). She wears light gray eyeshadow and has a long, bushy tail which ends in several tufts of fur sticking out in various directions. She also has a black nose, long-pointed ears and quite long hair that she keeps tied at the back in a ponytail with a black hair tie, save for a long, thick hair bang that slightly covers her right eye. Her pointed cheeks are a little fluffy. Her fangs protrude from her mouth which is often in a natural frown.

For attire, Whisper wears a cream-colored tube top, light gray leggings, and a dark gray cloak, in which she keeps six Wisp canisters. The cloak also has black and dark gray pockets seen on the shoulders, she sometimes takes off the cloak when off-battle.

Whisper wears an outfit geared towards combat. This includes dark gray arm sleeves with black elbow pads, dark gray and light gray gloves with visible black claws, and dark gray knee sleeves with black knee pads. She sports military-fashioned black, dark gray, and light gray boots. In the past, Whisper was excitable and bubbly, much like Tangle the Lemur. Even then, she still took her missions and fights seriously. Whisper also used to be more outspoken, eloquent, and joyful, but due to the trauma that Dr. Eggman and Mimic had caused her by ensuring the demise of her friends, she grew much more silent and reserved. Since then, she has been more shy, cautious, and distrustful of others, preferring to be out of the spotlight and in hiding. In the present, Whisper is also a rather mysterious individual with a quiet and withdrawn personality. Very soft-spoken, she speaks only when the situation calls for it and, true to her name, in a very low volume, rarely uttering more than a few words at a time. She also values her personal space and limited her interactions with others, fearing that if she made new friends, she could not handle losing them too. When in social situations, Whisper usually exhibits a rather bashful side of herself.

While Whisper is cautious and mistrustful of other people, she exhibits a strong bond with her Wisps (tiny elemental creatures) that is based on trust and friendship, as illustrated by their reception of Sonic the fastest hedgehog in the world persuading her to trust him, and the Wisps' willingness to stand up to Badniks (bad robots) in order to defend her. Due to the trauma she had suffered from losing the Diamond Cutters to Dr. Eggman and Mimic the Octopus, Whisper's emotions have a tendency to get the better of her, which almost resulted in her recklessly destroying a computer with important information on it in a blind rage. Another example was when she learned of Tangle's (the lemur) infection from the Metal Virus, which made her upset enough to make a fruitless attempt to run back into a town filled with Zombots (metal zombies) that could infect her as well in tears for her friend. Whisper's emotions can also cause her to make irrational decisions, such as attempting to assassinate Dr. Eggman or using her Wisps against a Dynamo Cage-wielding Surge. Unless someone keeps Whisper in check, there could be consequences.

Whisper's mask scope and Variable Wispon can be short-circuited via a Zeti's (creatures that appear in the Sonic the Hedgehog series. They are a fabled race of demons native to the Lost Hex that is led by their strongest specimen, Zavok. For a scheme, Dr. Eggman enslaved a group of Zeti known as the Deadly Six, only for them to rise up against him due to Sonic the Hedgehog foolishly disposing of the cause of their enslavement. However, the Zeti were defeated by Sonic before they could achieve their goal of destroying Earth.) power over electromagnetism, which can leave her unable to do anything so long as they are short-circuited. If she so happens to have her mask on or have one of her Wisps inside her weapon at the time, both of them can end up getting shocked. Whisper is an expert marksman and a master of stealth, able to infiltrate areas undetected and hit distant targets with her Variable Wispon without being detected by friends or foes alike. Her natural aptitudes are further enhanced by her unique equipment. She seems to prefer positioning herself on high perches and snipe enemies from a safe distance, but is able to hold her own in melee combat as well, with or without her Wisps. She is also a trained fighter in war like situations. She would not open up to anyone unless she has known them for months. Dosent talk much unless forced too. Shuts most everyone out. So traumatized, no one ever knows what she's really thinking or feeling, though that also has to do with her mask.

Potential love intrest: Tangle the Lemur (She is an anthropomorphic ring-tailed lemur from Spiral Hill Village and a member of the current generation of Diamond Cutters. She first became acquainted with Sonic the Hedgehog and his friends during the fallout after the Eggman War, having sprung into action to defend her village from one of the Badnik hordes terrorizing settlements across the world. Since then, she has been a recurring participant in the adventures of Sonic and his allies.)
