Almost forgot I had these. Just a bunch of thumbnail doodles of the guys from same universe as this picture. You can also check out the stories they're from in the links on that page.

From top-left to bottom right, as told by Shep:

Jared 'Jare' Kuznetsov: Jared's daily life is one big ego-trip. The world clamours to watch the world-class bodybuilder, astonished to see him bigger than his was last at every competition. Narcissistic to a fault, the giant white wolf will gladly push you out of the way if you're standing in front of his mirror, just to get a better look of himself. Jared's ambitions are limitless, there is nothing he won't do to spread his empire and celebrity. But don't be fooled by his spoiled demeanour and lavish lifestyle; fuelled by said ambition, Jared works hard to build his image. From working with talent agents, to working his ass off in the gym, Jared won't stop until his name is on every damn product you buy. He'll do anything if it furthers himself, but if it doesn't, he's about as lazy as can be. Sometimes that even includes loving his own husband.

Jonathan-Jackson 'JJ' Carter: A big grumpy tiger, JJ is Jared's loving husband. JJ had always been a warrior; a football star at every level of play. He was as household a name as his husband, but took a backseat, choosing to coach his university's football team; choosing stability over the lifestyle his husband so often promotes. And while he did it to be closer to Jared, as the wolf's career soared, he found himself almost... alone in their stately large home. Prone to keeping things to himself, no one, not even his husband, knows how deeply unsatisfied he is with his marriage; though, his anger does surface from time to time, just ask his boys out on the field how much of an ass he can be. He's thought about leaving Jared, but after two failed courtships with different high school sweethearts, the fear of finding nothing is gripping.

Devon 'PH' Renard: The perfect Gary-Stu. :P But, if I had to give him a personality, he'd be one sly fox. While he's got the body to muscle through anything, this veterinarian knows a thing or two about finesse. Ever the charmer, he'll have you wrapped around his finger before you've even told him your name. That being said, the guy holds more secrets than your government. He'll be pleased to make your acquaintance, but don't expect friendship. Slow to trust, he'll learn a lot more about you than you'll ever know about him.

Stephen (Étienne) 'Steve' Collins: If it walks on two legs and has an ass, chances are Steve's peeper's been in it. A proper Frenchman (well, half-French) at least he'll take you out before pluggin' your choice of hole. Steve's always been confident, sometimes brash, but he often shies away from asking for the things he truly wants in life. He almost missed out on being with his dear husband, Devon. It took him years to build up the courage to ask his hubby to go through with an adoption. And sometimes, he looks at his fellow bodybuilder and best friend, Jared, and wonders if he should ask how he's getting so big...

Walter 'Walt' Graves: There are two sides to Walt: the fun-loving, everyone-wishes-he-was-their-dad figure, and Agent Graves. Him and his husband, Tim, are quite the couple; they get invited to all the neighbourhood barbecues, and everyone loves Walt's famous ribs. He's loyal to his friends, generous to those that aren't, and seems like he could never make even one enemy. It's nearly impossible to get him mad, nothing seems to faze him. But, all it takes is to raise your hand against his husband and soon, you're staring death in the eye. Walt wonders what life would be like if him and Tim were more... normal -- what it'd be like to not have to sleep with a gun underneath his pillow. But, as Tim's field of work always seems to invite trouble, those days seem far away. His greatest fear is that this'll all become routine, that they'll never know a peaceful existence and that putting a bullet through someone's skull will be his job forever.

Timothy 'Tim' Fessenden: Tim's always noticed year after year that during his biology lectures, the student population is decidely more female than male. It also doesn't help the hunky rat that he blushes profusely whenever a 'cute' student wiggles their fingers at him. He sometimes can hear a wave of 'aww's from the crowd every time he squeaks. Dr. Fess also conducts research on muscular hypertrophy, AKA, muscle growth. Taking up the mantle from his father, Tim works, sometimes in secret, to develop serums for government projects. A size-queen, Tim loves the size of his hubby, his friends... oooh, just about any big guy. And while he's a pretty imposing figure himself, people often remember him for his big heart, moreso than his big biceps. Walt sometimes questions his husband's altruism, but everyone knows who pulls the leash in the relationship, always going along with Tim's plans to fix BIG problems. And there's a lot of big problems to fix in their part of town; monstrously-sized men terrorizing the town as frequently as it rains. Confronted with adversity, Tim is often reminded that despite his beefy physique, numerous piercings and tatted up arms, he's still the small, scared rat he's always been. But he always pushes past the feelings of dread, making him quite possibly the bravest rat there is.

Welp, there it is. The descriptions aren't really canon, I added quite a few embellishments.
