Personality
+ Confident Competitive Watchful Protective Reliable Thick-skinned Loyal
Territorial Stubborn Pushy Impatient Tactless Self-condemning Temperamental
Confident, Competitive, Tactless. Renji knows he's big, strong, and good at what he does. No point pretending otherwise. He doesn't intimidate easily and he doesn't shrink himself down to make others feel comfortable. All that presence can be a lot to stand in front of, but he's got no interest in stepping on weaker people just to prove himself. He takes competition seriously, though. Anyone who gives him a real run for his money earns his respect, and he'll openly admit when someone's beaten him fair and square before demanding a rematch. Trash talk and bravado come with the Valcoguard life, both roll straight off him, and he'll laugh off an embarrassment without much trouble. Renji is blunt, physical, and used to trading insults with people who know how to throw them back. He doesn't always adjust when somebody communicates differently and might hit a sore spot before realizing they were never playing along.

Protective, Pushy, Impatient. He grew up as the oldest of five, and it shows. He's not the type to hover or handle someone with kid gloves, but he'll pull them out of a mess and scold them for getting into it. His mentoring style is to lead by example, then let them figure out the rest on their own, even if they've gotta stumble a few times. He wants everyone he cares about to be able to stand on their own feet! He just has trouble standing idly by when he thinks they can't. Renji assumes he knows best, and if he thinks a problem is serious enough, a refusal won't always stop him from handling it himself anyway. He's very much the act-first-apologize-later type. His fuse was way shorter as a teenager and he's better about picking his battles now, but nobody would call him patient. He runs on instinct and gut feeling, so if you're the type to overthink or second-guess, he's probably made up his mind before you've finished your sentence.

Loyal, Territorial, Stubborn. Once Renji considers someone one of his own, his loyalty is absolute. Fights, betrayal, and anger may create distance, but none of that will make him leave someone he loves to face trouble alone. All that loyalty comes with a territorial downside though. He expects his place at their side to be a given and hates being treated like an outsider. With people he trusts and likes, he gets more openly affectionate. This involves crowding into their space and leaning his weight against them or ruffling their hair, because he assumes they'll shove him off if they want him to stop. Like all big dogs, he sometimes forgets his size. Around strangers he becomes more watchful, crowding close to his partner so nobody can mistake their connection. A long-distance relationship would probably drive him out of his mind. Once he's decided something, good luck convincing him otherwise. This serves him well when persistence is needed. It serves him considerably less well when he's wrong and acts like he can outlast the facts.

Self-condemning. Renji has no shame about being a hybrid/canid, but his surges are a different story. He blames himself for the violent and sexual urges they cause and often hides how badly he's struggling to control them even with medication.
Appearance
GENERAL:
Built like a fridge. Tall, with broad shoulders, a wide chest, thick arms, and large hands. His height always gets people's attention first, then the sheer amount of muscle packed onto him. His hair is thick and wild, predominantly black under a vivid red crown. Longer red sections sweep across his fringe and back between a pair of large black wolfish ears with white inner fur. He has warm tan skin, red eyes, and pronounced canines that show whenever he grins.

SCARS:
A pale vertical scar under his left eye. Several more cross his chest, some broader and more visible than others.
NSFW / EXPLICIT DETAILS:
Anatomy: Varies by setting, but usually AMAB.
Cock size: Large and thick. His cock otherwise looks human, apart from the slightly more sensitive tissue at its base, which swells into a knot when affected by a surge.
Knot: His knot usually only swells during a surge. Outside these cycles, the tissue at his base does not form a tie. During a surge, it expands during sex and keeps him tied to his partner until the swelling subsides. (Can be removed in settings where his anatomy is fully human.)
Other: Renji has considerable stamina and produces more precum and semen than an ordinary human. He also recovers quickly between orgasms. These traits become more pronounced during a surge, when his refractory period shortens considerably and he needs to claim his partner, breed them, and tie them on his knot.
Background
Setting. He comes from a near-future parallel Earth where genetic engineering developed several centuries ago. Worsening environmental conditions pushed governments and private companies to begin modifying humans with traits taken from animals already adapted to extreme climates, pollution, and other hazards. The programs were promoted as humanity's best chance at survival. Many of the first subjects had little choice about taking part.

Childhood. Renji was born the oldest of five and grew up with four younger siblings underfoot. He was the older brother who dragged them into whatever he was doing, taught them by letting them fail, and stepped in if they got into trouble they couldn't handle. He was also a temperamental kid with a short fuse and got into fights more often than anyone in his family wanted, especially after hybrids in his hometown were blamed for a break-in at a nearby genetics clinic.
Hybrids. Genetic modifications were hereditary, and the descendants of those subjects eventually grew into established hybrid populations. By Renji's lifetime, hybrids have been ordinary members of society for generations. Some can pass for baseline human at a glance, while others have bodies that require specialized clothing or medical care. Renji's family comes from a long-standing canid bloodline and has no direct connection to the original programs beyond sharing that history.

Valco Accords. Abuse within the early modification programs eventually led to the Valco Accords, named after the city where they were signed. The accords recognized hybrids as full citizens and established strict rules governing genetic work. They also created protections around biological samples, making it illegal to collect or use someone's genetic material without informed consent. The accords are accepted across most major states, although enforcement varies, and some local authorities still treat crimes against hybrids as a low priority.

Valcoguard. The Valcoguard was created as the investigative and enforcement arm of the accords. It is separate from ordinary police and specializes in crimes involving illegal genetic work. Its agents trace trafficking networks, seize illegal research, and recover hybrids held inside laboratories.
Abilities
Canid Senses
Renji's hearing and sense of smell are both far sharper than a human's. He can hear quiet movement through walls, recognize people by scent, and follow traces they left behind in an area. He also notices smoke, blood, chemical leaks, and similar changes before most. Strong smells and high-pitched noises can overwhelm him for exactly the same reason.
Hybrid Physiology
Renji's strength far exceeds ordinary human limits. He can lift a small car clear off the ground, and his hybrid body can withstand blows that would seriously injure most people. His high pain tolerance makes him exceptionally difficult to put down in a fight. These traits give him excellent defensive capabilities and make him well suited to search-and-rescue and protection missions, where he can shield others, clear debris, and carry people out of danger. His offensive power is moderate overall. He is deadly at close range, though his options against distant targets are limited.

His ears and tail make his moods difficult to hide. His ears turn toward anything of interest and flatten when he gets overstimulated or annoyed, and if the emotions are enough, the hairs at the nape of his neck raise like hackles. He also runs hotter than non-Canids.
Surge
Canids tend to have high libidos, but some bloodlines also experience periodic endocrine cycles. Renji calls his a surge. This can last from days to weeks and makes his body run even hotter than usual. He grows restless, sleeps badly, and reacts much more strongly to touch and scent. Sexual release takes the edge off for a while, but the need always comes back and grows harder to control as the cycle continues. If Renji ignores it for too long, the surge starts eating away at his self-control. As instincts take over, he may lash out or become violent. The cycle only ends once it has run its course, which is why his suppressants are a necessity if he has no other outlet.

Renji grew up in a small rural village as the oldest of five. His parents owned an auto repair and towing garage, so he spent much of his childhood passing tools, helping with heavy jobs, and learning how machines worked by getting his hands on them. His four younger siblings were rarely far behind. Renji let them tag along, showed them how to do things for themselves, and stepped in whenever their adventures got out of hand.

Everyone in the family has a heteromorphic Quirk, though its traits manifested differently in each sibling. As Renji grew taller, broader, and more visibly powerful, people around the village began avoiding him, even treating him as dangerous before he had done anything to deserve it. His younger siblings faced the same suspicion, and Renji got into plenty of fights defending them during his teenage years.

His first surge began during puberty. The sudden hormonal cycle was difficult to control, and the local doctors had never treated anything like it. They recognized it as a complication of his Quirk, but they had no idea how to manage it beyond monitoring his condition and waiting for the cycle to end.

Renji wanted to become a hero because his Quirk made him exceptionally suited to rescue work. He was also sick of watching heteromorphs like his family get treated as dangers for simply existing. After he was accepted into U.A., the school's medical staff referred him to a specialist team at Central Hospital that treated illnesses and complications caused by Quirks. The team had recently developed a suppressant for similar endocrine conditions. It reduced the worst of his urges and allowed him to sleep while a surge ran its course.

After graduating, Renji was recruited as a sidekick by a top hero agency. He specializes in rescue, civilian protection, and containing threats at close range. He has taken suppressants since his time at U.A., but years of regular use have caused his body to build a tolerance. Each dose now wears off a little sooner than it should, leaving him restless and painfully worked up before he can safely take the next one.
