Distressed Dude: He frequently gets himself into situations where Zayats has to rescue him.
Dreadful Musician: An inconsistent part of his character is his competency in music. But quite often, he will play ukulele with all the skill of a toddler, and his singing is one of his greatest crimes.
Drives Like Crazy: If an episode features him using a vehicle, he will drive it recklessly.
Evil Is Petty: While most of the cartoons depict him having some kind of motivation for harassing Hare, such as wanting to eat him or get back him back for some perceived slight, other times, he'll have none outside of just being a bully.
Exposed Animal Bellybutton: On a few occasions, Wolf wears a shirt or a tank-top revealing his belly button. In Episodes 1, 16 (beach episodes), and Episode 9, where he was wearing pajamas this is noticeable.
Hates Baths: He's groomed against his will in episode 14, leaving him with his hair in a perm, his shirt tucked in and a bow around his now-brushed tail. As soon as he gets a glimpse of himself in the mirror, he angrily messes up his hair, rips off the bow, and un-tucks his shirt.
Hair-Trigger Temper: Or in this case, hare-trigger temper! Sometimes, he'll chase the Hare for no better reason than to get back at him for perceived slights.
Hidden Depths: Some episodes show him to be a competent musician.
Silly Walk: He has a very swishy, effeminate walk, especially when he's drunk.
Smoking Is Not Cool: He is almost never seen without a cigarette in his mouth. The first scene of the series is him kicking over a trash can to try and find any used cigarettes that are still good. He even offers a cigarette to the Hare in one episode, to which the Hare declines. In another, he tries to smoke the Hare out of a phone booth with an entire lit pack and nearly chokes to death as a result.
Stalker Without a Crush: In every episode, Volk chases after Zayats; occasionally, he snuggles or coochi-coo him after catching. Despite this, Volk's obsession definitely isn't meant to be romantic or sexual.
Wild Hair: He has untamed black hair and is a reckless and rather aggressive predator.
Ungrateful Bastard: Some episodes have the Hare either making peace with or showing no animosity towards him, yet the Wolf still chases after him. In episode 2, he gets saved from drowning and is necessitated by two beavers in a motorboat, and he kicks them out to steal it.
Unsympathetic Comedy Protagonist: He's the focus character, with the episodes following his antics as he tries to catch Zayats; he has many negative personality traits, being a bad-tempered bully/hooligan/stalker, and his misfortunes are the main source of comedy.
Zayats (Заяц), or The Hare
All-Loving Hero: He holds no animosity towards the Wolf, only acting out of self-preservation when he's being preyed upon, and sometimes saving the Wolf when he gets himself in trouble.
Badass Adorable: Zayats may be innocent and sweet, but isn't afraid to stand up for himself.
Bunnies for Cuteness: He is a sweet, cute, innocent hare with a boyish appearance and an adorable voice.
Inconsistent Coloring: In the original shorts, his fur is consistently brown, but in the TV series it's sometimes light grey, and in the short PSA shorts, his fur is solid white with no blush.
It's not known if it's intentional, but hares actually can change their fur color to white in the winter, and most of the PSA toons are about weather-stripping windows during cold seasons. However, the low quality and limited color pallet of the shorts suggest the color change could also be for budgetary reasons.
Stock Animal Diet: He is a hare, and he eats carrots. In one episode, he offers the Wolf a carrot; the Wolf declines.
Tertiary Sexual Characteristics: Inverted. Despite being male (the Russian word "Zayats" is masculine by default), he has thick eyelashes, pink cheeks, engages in feminine activities, and is voiced by a woman.
Vague Age: He has the appearance and attitude of a child, and is often in settings that are largely populated by children (a circus, a fairground), yet appears to be old enough to have his own apartment where he lives alone, and is occasionally implied to be employed where the episode takes place. His parents are seen in the pilot episode, where he is a toddler in a stroller, but in the PS As there is no question that he's an adult. In episode 7, he boards a boat with a ticket for children.
Wholesome Crossdresser: Unluckily, he's dressed like a famous Russian singer and he happens to get stuck on stage in front of hundreds of fans.
You Don't Look Like You: In the PSA shorts, Zayats is redrawn as a taller, pudgy white rabbit with thick limbs, no blush, tiny black irises with no color, and his clothing colors vary.
Your Size May Vary: Generally, Zayats is about waist high to Volk, but in the PSA shorts, he's bumped up to neck-high.
