Humphrey is a slender and average gray omega, and he is not well-built. His fur is many different shades of gray. He also has a whit underbelly, a white face with a gray stripe down to the nose, and blue eyes.
Humphrey is an ideal omega wolf: Good-natured, witty, a good sense of humor, loyal, and kind (as well as a skilled peacekeeper, which is technically his job in the pack as he's the omega leader of the Western pack, presiding over the other omegas, keeping the peace and doing their best to diffuse tension, which seems to be the only responsibility he takes seriously).
Humphrey enjoys making jokes, playing games, hanging out with his friends, and when he sets his mind on something, there's no stopping him. Humphrey seems to be the jealous type, seen when he interferes with Kate and Garth at the Moonlight Howl, and calling Garth "Barf" out of pettiness and envy.
Humphrey is also a skilled improviser and brave as in the first film, he used quick-thinking to save Kate from a mudslide, some well-executed flattery to convince Marcel to help them again, and while he doesn't have the prowess of Kate, he has performed his share of bold and daring feats, even though sometimes his irresponsible nature can be a problem.
Still, Humphrey is a true friend and loyal to all important to him, to his pack, his friends, and especially Kate, which is proven several times through out the movie as when his loyalty overrode his intention to run away from his problems and when he risked his life to protect Kate from the caribou stampede, proving to Winston his love for Kate was true. His loyalty was also proven when, during the train ride while Kate fell asleep, Humphrey might have chosen to not wake her up in time to get off for Jasper and run away with her, but he didn't. In addition, Humphrey is among the most beautiful howlers in the film, which is what helped Kate realized that her heart belonged to Humphrey. Humphrey is sometimes seen walking or standing on his hind legs, even though other wolves at the Moonlight Howl were shown doing this (as well as dancing). Humphrey seems to be a bit claustrophobic as he was hesitant to get into a cramped camper after having been dropped into Idaho in a cage. He also likes music as he danced an air-guitar to some playing on a radio (where he learned how to air-guitar is anyone's guess) in the movie.
In the third film, Humphrey seems to be a bit more moody than usuall. He gets annoyed easily and is not really wanting to coach the team for the games. He also is seen giving a dirty look to the Northern team's coach, Nars. Along with his moodiness, he is shown to be extremely protective in the end of the film by yelling at Claudette and telling her to quit flirting with Fleet.
In the fourth film, we see an entirely new side ot Humphrey. Hes shown to have the ability to fight, as he takes down two alpha wolves with Kate in the final battle to protect Daria.
In the fifth film, Humphrey's abilities to fight are developed even more, as he's shown attacking the trappers to save his family, almost risking his life. However, he still maintains his Omega status as peacekeeper, and still has his fun-loving side.
He growing up after being born an Omega wolf, Humphrey befriended three other Omegas named Salty, Shakey, and Mooch, and together, the four of them invented logboarding by means of a halved hollow tree. The first time didn't go so well.
Humphrey also befriended Winston's daughter Kate and is secretly in love with her, which goes severely against pack law: Alpha wolves and Omega wolves aren't allowed to mate. During another of their hill-sledding games, Humphrey caught Kate before she left to attend Alpha School, whereupon Winston reminded Humphrey that a relationship deeper than friendship between him Humphrey and his daughter was prohibited. While Kate was walking away Humphrey glancing at Kate's rear end while shaking his head left and right looking at her curves(or another words looking at her butt) before Winston blocked his view. By next spring, Humphrey had become a teenage Omega leader, and he and his friends had mastered hill-sledding (except for figuring out how to stop) and discovered that Kate had returned from Alpha School as a trained Alpha. When Humphrey expressed an interest in taking his friendship with Kate to another level, his friends reminded him that it wasn't allowed, but he didn't pay attention to them.
As they watched Kate, Hutch, and Candu start hunting caribou, they noticed two wolves, Claws and Scar, from the Eastern pack interfere, resulting in a caribou stampede. The Omegas were impressed and awestruck by Kate's Alpha prowess, as she executed amazing moves to save Claws and Scar from being trampled to death. When the Western alphas (excluding Kate) started a fight with Claws and Scar, Humphrey and the Omegas stepped in to prevent anyone from getting hurt, using their playful and affable natures (as well as throwing Mooch to bodyslam them). Winston appeared, ordering his Alphas and daughter to the den, the Eastern wolves to go home, and complimenting and congratulating the Omegas on their jobs as peacekeepers.
As Kate was about to leave, ashamed of her first hunt ending in failure, Humphrey tried to cheer her up by saying that instead of caribou, the pack could always eat berries. However, Kate didn't want to listen and just kept walking away. Later, the Omegas try to brighten up the pack's hungry mood by offering berries in place of meat (the wolves growled at them) and squirrels as a second choice (this was met with wagging tails and drooling tongues).
That night, Humphrey and his friends went to the Moonlight Howl at Howling Rock, where again he was discouraged by his friends in pursuing Kate, and he wasn't happy to see Kate taking an interest in another wolf named Garth, whom Humphrey teasingly calls "Barf." He notices Kate separating from Garth and they had a conversation/argument regarding Garth, Humphrey calling Garth a dud as he heard Garth's horrid howling while Kate was trying to be positive about Garth when they're both tranquilized in their rear ends by park rangers and end up shipped to a park in Idaho.
They notice a goose and duck playing golf (or "some kind of weird game", as stated by Humphrey) and go over to investigate. The goose, named Marcel, pretends to not be afraid of wolves, and distracts them by pointing and exclaiming, "Quick! Look behind you!", then whacks Humphrey on the head with his golf stick, and runs away from the duo. Humphrey forces him down (after a chase through a rocky river, bramble bushes, and into a mudhole). Marcel and his duck caddy named Paddy reveal that Humphrey and Kate were relocated to repopulate, much to Humphrey's delight and Kate's dismay. Kate has to get back to Jasper Park and convinces Marcel and Paddy to help them. Marcel and Paddy direct them into the back of a truck owned by a couple headed straight for Jasper. As they travel along the road, Humphrey gets into some of the couple's things and enjoys the music they're playing on the radio. Later that evening, the couple stop at a gas station and Humphrey has to get out and pee. Unfortunately, he gets sidetracked by a cupcake near a dumpster and the gas station employees see him and mistake the cream on his mouth for foam and think that Humphrey's a rabid wolf. They take aim at him with a gun (making Humphrey wet himself in fear), forcing Kate to give up their ride to Jasper and save Humphrey.
As they travel through the woods, Humphrey apologizes over and over for losing their ride and it begins to rain (he tries a raindance to make it stop raining until Kate enlightens him that raindances make it rain) and she goes on ahead without him.
When Humphrey catches up to her, he finds her hanging for dear life onto a ridge above a mudslide she tried to cross, and she's slipping. Thinking quickly, Humphrey swings on a vine (and humorously does a Tarzan yell) and tells her to grab his tail (which turns out to be very painful) before he swings her to safety. Kate loses sight of Humphrey and sees a mound of mud, thinking that he fell in, and tries to pull "Humphrey" out and thinks that she accidentally ripped off his tail until he appears for real. All Kate pulled out was a stick from a mudball. Then Humphrey suggests they find shelter for the night and Kate thanks him for saving her life.
In the morning, the two wolves are woken up by Marcel and Paddy, finding them in a lair, and they wake up with their noses touching (or kissing, depending on how the viewers look at it). Marcel berates them for losing the transportation that he and Paddy provided, but Humphrey's quick tongue and flattery helps them get another hope to go back to Jasper. Marcel and Paddy direct them to the Canadian Express, which will pass by soon on the other side of the mountain near them. Humphrey and Kate race up the mountain while also playing in the snow, where Humphrey notes to Kate that she's having fun for once. She goes ahead to look for the train and Humphrey meets a bear cub and starts playing with her. Humphrey then throws a snowball at the cub, accidentally making her cry, and Humphrey tries to comfort her and apologizes. This angers the cub's mother, who thought that Humphrey was trying to hurt her baby. Humphrey runs to Kate, who is sure that they can handle the bear, but her confidence is short-lived when two more bears appear. Humphrey tries to use a joke to placate the bears while Kate tries her Alpha training; neither work and they're forced out onto a log hanging by its roots from the top of the mountain. The bears then snap the log, making Humphrey, Kate, the log, and the bear fall down the mountain and down a steep hill of snow. Using his hill-sledding skills, Humphrey saves Kate (again) from the bear and they barely make it onto the train.
Humphrey and Kate laugh about the whole experience, noting the particulars and Humphrey brings up that they make a pretty good team, and Kate agrees. As the train is going along, they notice the full moon, and Humphrey, caught up in the moment, starts howling and convinces Kate to join him. Hearing his howl, how beautiful it is, deep down, Kate realizes she loves him, that this is who she belongs with, and starts howling with him, the two of them howling a soulful duet.
They soon fall asleep, but Humphrey is woken up by Marcel and Paddy, who are both flying alongside the train to let them know that they're just about to enter Jasper Park, and they call Kate Humphrey's girlfriend, which invokes Humphrey's feelings for her, especially when he sees how beautiful she is as she sleeps. Marcel and Paddy leave (not that they had a choice as they crashed into a billboard) and Humphrey wakes up Kate to let her know that they have arrived. They both try to say something, but Humphrey lets Kate go first, and she admits the past few days with Humphrey have been fun and a real adventure for her. Humphrey nervously tries to admit that he loves her, but Kate notices the Western and Eastern packs on the verge of war and runs over to prevent it before Humphrey gets the chance. The duo stop the fight before it begins and explain that they were taken to Idaho to repopulate, provoking Eve to jump to conclusions (as usual) and start to strangle Humphrey. Luckily, Kate convinces her mom that they didn't repopulate and Humphrey helped her back, and Eve immediately stops choking Humphrey, helps him up, and calls him a nice boy with her sweet persona. Then Kate announces that she accepts marriage to Garth, as was intended from the start, to unite the packs. This leaves Humphrey shocked and heartbroken. He had expected her to love him.
In the morning, before the wedding is about to begin, Marcel and Paddy arrive to see that Kate made it home and congratulate her on getting married (even though their faces express some awkwardness because they thought Kate was with Humphrey). Kate asks them who told them, and Humphrey appears, saying that he did, and Marcel and Paddy take off to give Humphrey and Kate some privacy. Humphrey places the flower Kate wore earlier in the film into her hair for her wedding (or one like it) and says that he has come to say goodbye. Kate asks where he's going, and Humphrey says that he is going to do some traveling, see where the train takes him, saying that it's a lone wolf thing. Kate says that she knows Humphrey the fun-loving omega, not Humphrey the lone wolf. He replies that he'll just be a fun-loving lone wolf and leaves. But the real reason Humphrey leaves is because he can't stay in a pack where the wolf he loves is married to someone else.
Marcel and Paddy directs Humphrey to another train. But at the last second, Humphrey realizes that he can't run away from his problems and feelings, and decides to go back to Kate. He runs into Kate and finds out that Winston and Tony are caught up in a stampede of caribou. Using a log, they ride down to save the two alpha leaders by providing the log as a shelter from the caribou, but Kate is knocked out, and Humphrey shields her body with his own while Winston and Tony growl and snarl at the approaching caribou to divert their course. But it seems that it's too late as Kate is apparently trampled to death. Heartbroken that he never got the chance to tell her he loved her, Humphrey begins to cry, and leads both packs in howling a requiem for Kate, but to their relief, Kate begins to wake up. Then the duo admits that they love each other (whispering in each other's ears). Seeing this (and that Humphrey had bravely protected his daughter), Winston convinces Tony to unite the packs under a marriage between his other daughter Lilly and Garth (as the two fell in love with each other during Kate and Humphrey's absence), effectively abolishing the rule of social class.With the packs united as one, the wolves celebrate at Howling Rock, the marriages of Garth and Lilly and Humphrey and Kate, the latter couple howling a duet at the summit of the mountain, leading to a happily ever after. In the deleted scene he is shown to be a playful adult wolf. He is trying to convince his wife, Kate, to howl with him, but she refuses. When he starts howling by himself, he looses his balance causing him to fall off the log he was standing on.
In their parents old den, Humphrey is helping Kate to get the den in order for the holiday. When Salty arrives asking him on how's life with Kate and says its "efficient". Humphrey goes with Salty to collect some moss, berries, and flower reefs. Humphrey greets his in-laws after a while a word that Runt has been kidnapped.
He acts as the coach of the Western Pack wolf team in the Great Wolf Games, starring his own pups.
Humphrey at first tries to stop the pups from going into the forest on request of Kate, but when he and his mate find out that Runt is trying to help Daria, he supports his son and the blind female wolf and helps them get to Rabbit-Poo Mountain. During the final fight, he shows his more violent side, knocking over an alpha wolf to protect Daria and his family.
Humphrey and Kate are out searching for food. They are suddenly trapped in a large snowstorm. They take shelter in a nearby cave to wait out the storm. Humphrey surprises Kate with blueberries, but she realizes that bear eat them and now realize they're in a bear cave. They hide from the bears. They attempt to sneak pass the bears but just as Humphrey makes it over he ends up getting cuddled by one of the bears.
- Kate - When they where young Kate told Humphrey she is going Alpha school and Humphrey was totally shocked when she told him about it. When Kate came back he commented on her alpha moves. When they were on the train Humphrey started to howl, he asked Kate to joined in and eventually Kate finally howled with him on the train. When Humphrey said he was leaving Jasper and Kate said "I know a fun loving Omega " At the wedding Kate said "I can't "& "I fell love a Omega" Then when Kate got hit by caribou Humphrey jumped to save her. When he thought Kate died he howled. But when Kate woken up she whispered in Humphrey how she feels and so did Humphrey as well.

- 'Again with the butt, these mosquitoes are out of control.'
- 'Is this about Barf?'
- 'That's not a good idea.'
- 'A simple boo would have sufficed.'
- 'Kate and Humphrey, World adventures, what do you think?'
- 'I just wanted to tell you, I lo...'
- At the end of the first film, it is unknown whether or not Humphrey and Kate are the new leaders of the pack, although there are hints:
- At the beginning of the film, Winston clearly stated that Kate was his heir for leadership of the pack; this said that by marrying Kate, Humphrey also becomes a future leader of the pack.
- Winston and Tony, by allowing the marriages of Garth and Lilly and Humphrey and Kate, abolished the rule of social class, effectively making Omegas equal with Alphas, making Humphrey eligible for leadership.
- Winston and Tony are implied to have retired from leadership when Winston asked him, "What do two old wolves do after they retire?".
- In the sneak peek of Alpha and Omega 2: A Howl-iday Adventure, Humphrey and Kate are seen living in what used to be Winston's and Eve's den, giving the impression that they are the leaders now. Also, Stinky states that he is the future leader of the pack, which would only be possible if they were the leaders.
- But this could also be questioned, seeing how Stinky addresses Winston as "great leader" early in the fourth film.
- While in Alpha and Omega 5: Family Vacation, Humphrey tells the pups about his embarrassing encounter with a moose of Marcel flew him into the moose's butt and was farted on much to his shock and embarrassment for which he had to go to counciling.
- In the first film Humphrey's encounter with a moose happens in three different scenarios with first in the trailer Humphrey flies into the moose and gets his head has clattered face-first into its bottom, possibly getting its head lodged in the moose's rectum in the process. The second he was wedged between the moose's antlers as seen in the film and the third was him paragliding into and literally hugging the moose's butt while being farted on. He screams as the moose lifts his tail as if he was going to poop on him. This was not seen in the first film due to a different script.
- Humphrey finds out that he is ticklish when Kate tickles his nose with her tail while rescuing her.
- It appears that in Alpha and Omega 2, Humphrey matures by not wanting to hang on a vine to get across the stream, and when Kate wanted to log sled to the Eat Food, Get Gas station.
- Due to their similar appearances, people on the Internet mistook Winston to be Humphrey's father before the original movie was released when Winston is actually the father of Kate. Although, by the end of the film, Humphrey becomes Winston's son-in-law, and they seem to have a good relationship.
- Humphrey's name in Teutonic means "Support Peace," which suits him for his role as a peace keeper. However, he's been a jerk to Garth because of being jealous to marry Kate.
