Watchdog Man is a young-looking man with a blank and uninterested look on his face. He dresses in a full-body dog suit with a red collar, with his face showing where the dog's mouth should be.
Watchdog Man has been shown to be very blunt and nonchalant. He also has a habit of wearing his costume all the time, even keeping it on when he bathes. His table manners are also bad since he eats like a dog and is never seen using a fork or spoon. He acts like a dog at all times, speaking sparingly, sitting on his haunches while alert or loitering, and curling up in a dog bed while asleep. He takes a stance on all fours while fighting, rather than standing upright to confront enemies.
Like a loyal and well-trained dog, he is solely interested in protecting his territory. Though he solely performs his hero duties there in Q-City, he relentlessly hunts down and dispatches any mysterious beings there, ripping them apart as quickly and savagely as he's able. He often piles up and perches atop the corpses of the mysterious beings that he kills.
Though willing to brutalize human attackers, he notably holds back and does not go for the kill, instead beating Garou down until he escaped Q-City's limits. He can be rather impish when fighting human criminals, as seen when he counters Garou by "shaking" his attacking hands.
His expression is constantly deadpan, making him difficult to read. Similar to Saitama, he's also very prone to boredom, as seen when he's unimpressed with Bang's Water Stream Rock Smashing Fist during a sparring match between Bang and Metal Bat at Bang's dojo, and decides to go back to Q-city to fight monsters.
Abilities and PowersEdit
As an S-Class hero, Watchdog Man is very powerful. A testament to his prowess is that he was left in charge of Q-City, which is considered to be the most dangerous city in terms of number and average disaster level of Mysterious Beings. He is also described to eliminate monsters like no other. In his early days as a hero, he managed to rip off the head of an enormous monster without incurring an injury. Watchdog Man is also strong enough to defeat Garou effortlessly without using his full strength. He has never lost a fight against monsters before, and is respected and feared by heroes and villains alike.
Immense Strength: Watchdog Man possesses an extreme amount of raw physical strength, being able to easily rip apart multiple monsters far larger than himself with his bare paws. Watchdog Man was also strong enough to severely wound Garou while holding back.
Immense Speed and Reflexes: Watchdog Man is extremely fast, being able to rip apart multiple monsters within a few seconds. Despite being attacked by around 30 monsters from the Monster Association at the same time, Watchdog Man managed to quickly defeat them and came out of the battle without a scratch, surprising Garou, who was watching the fight. He was also able to effortlessly keep up with and block all attacks from Garou during their fight, then retaliated at the speed that the Hero Hunter was unable to counter. Garou himself even commented on Watchdog Man that the hero's speed far exceeded his expectations.
Immense Agility: Having excellent physical prowess, Watchdog Man is incredibly athletic and moves in a way that resembles that of a savage animal during combat. He is able to climb from one place to another, which makes it hard to follow his movements. Furthermore, his amazing speed and reflexes also grant him the balance to match his unpredictable attacks.
Dog Attributes: Watchdog Man possesses characteristics usually associated with dogs. He has an absolute sense of smell and hearing. His senses allow him to instantly detect any monster who enters his domain. He noticed someone farted during a meeting when none of the other S-Class heroes noticed.
Expert Hand-to-Hand Combatant: Garou described Watchdog Man's fighting style as that of a beast or a monster rather than a human. Garou also noted that Watchdog Man lacks any special techniques or weapons, relying only on simple hand-to-hand combat, very much like Saitama. However, Watchdog Man's skills are demonstrated to be rather powerful, being able to counter Garou's martial art techniques, including his Water Stream Rock Smashing Fist. As a result, he can counter all of Garou's movements perfectly, since Garou's techniques are designed to be used against human targets, not animals, as well as the fact that Bang didn't teach him how to fight animals. When he countered Garou's attacks, his blocking resembled the dog-like behavior of giving his paw for a handshake. This, along with his physical prowess and senses, makes him one of the few heroes capable of beating Garou with no problems.
