Ham-Ham Gang ; :Voiced by:
Kurumi Mamiya (Japanese),
Chiara Zanni (English) :Owned by Laura, Hamtaro is a courageous Ham-Ham who's always ready to help out his friends and his owner Laura. However, he cannot stand being ignored by Laura. He is clueless about many things being that he is of an innocent nature, especially love (much to Bijou and Sparkle's dismay). Hamtaro makes the most of his life as a
golden hamster (8.6cm) and lives each day in happiness hoping to make more friends and have fun. Hamtaro usually ends his sentences with "noda" (のだ) or "nanoda" (なのだ), a phrase often used by playful characters in the Japanese version. This is omitted in the English version. In both Japanese and English versions, he says such things as "Hamha!", "Heke", "Packa-packa" ("kaji-kaji"), and "kushi-kushi". ; :Voiced by:
Kazusa Murai (Japanese),
Chantal Strand (English) :Owned by Maria. She is a somewhat unworldly hamster who loves her blue ribbons, but she is not above getting dirty when she needs to help her friends, and has been known to be generous and helpful. She used to live in France before moving to where she is now, but she feels attached to Japan and has even refused to go back to France. In the Japanese version, she speaks normal Japanese and adds the words "dechuwa" (でちゅわ) (most likely a hamster version of "desu wa") at the end of her sentences, while the English version of Bijou has a French accent. The name "Bijou," is French for "small, exquisitely wrought trinket", or it can also mean "jewel". She has a huge crush on Hamtaro (this is proven in the first episode, when she winked at him after their dancing performance) and is always touched by Boss's affection towards her. ; :Voiced by:
Rikako Aikawa (Japanese),
Saffron Henderson (English) :Owned by Kana. Oxnard is Hamtaro's best friend in the series and the first Ham-Ham he meets. Oxnard is a bit clumsy at times and has a love for delicious food, especially sunflower seeds (of which he always carries one around). He breaks down in tears when he loses the sunflower seed he carries around. He looks up to Boss and often tries to train with him whenever possible, wanting to be as strong and brave as him. He was originally an easily frightened Ham-Ham, but he has become braver and more dependable in recent episodes. Oxnard has a crush on his close childhood friend Pepper. His Japanese name translates to "calf", which is probably referring to his spotted cow-like fur and his large appetite. ; :Voiced by:
Kentarō Itō (Japanese),
Ted Cole (English) :A wild field hamster who wears a helmet and carries a shovel. The self-proclaimed leader of the Ham-Hams, Boss has a huge crush on Bijou. He often tries to look like he knows everything, only to have it backfire in his face. He has a bit of a temper, but he is very dependable, courageous, and nice, even shy at times (especially around Bijou). Because he is a field hamster, he is more familiar with nature and is more independent compared to the other Ham-Hams. He has even developed a field hamster sense that instinctively tells him what kind of weather is approaching. However, he cannot deal with the sea as he is prone to sea sickness. Near the end of
Hamtaro: Ham-Ham Heartbreak, it is hinted that he has a small crush on Harmony. Later in the series, Boss develops a crush on other girl-hams, such as Gelato and Oshare. ; :Voiced by:
Rei Sakuma (Japanese),
Tabitha St. Germain (English) :Owned by June. Considered to be a very maternal Ham-Ham, as she often takes care of Penelope and tends to Cappy. She loves the color pink and always wears her pink scarf. Dexter and Howdy often fight for her affection, but she does not seem to notice (sometimes acting like a mediator for them). She feels that she is too young for a relationship anyway. Her Japanese name translates to "scarf", while her English name is based on the word
pashmina. ; :Voiced by: Kaori Matoi (Japanese),
Jocelyne Loewen (English) :Owned by Kylie. Considered the youngest of all the Ham-Hams, Penelope is usually never seen without the cover of her yellow blanket (though a few seconds in the opening theme show her blanket coming off, revealing her brown and white fur). Although she is friendly to everyone, she feels particularly attached to Pashmina. Being innocent and naive, due to her age, she gets into trouble more often than most of the other Ham-Hams. In season two, she has shown some cross-species affection for Herbert the Pig, a boy by the name of Ethan (Kylie's younger cousin), and a rabbit at Ethan's school. Unlike the other Ham-Hams, and perhaps because of her young age, Penelope can't say anything more than "Ukyu" (うきゅ) in the Japanese version, and "Ookwee" or "Ookyoo" in the English version. ; :Voiced by:
Takako Honda (Japanese),
Brad Swaile (English) :Owned by the eldest son of a bookstore owner (though it seems that the bookstore owner's daughter is the one who cares for him). He always carries a book with him, and is often turned to for information. He seems to know a lot about
science and
literature due to his love of reading. He is a little taller than the other Ham-Hams, partially due to his tall ears. He has a crush on Sandy, though it is never initiated until Hamtaro tells him about Sandy's feelings. ; :Voiced by:

Her interest in rhythmic gymnastics have been influenced by Hillary, who is a gold medal gymnast. She has a crush on Maxwell. While in the English version it might seem that the two have confessed their affections, a Japanese episode confirms that they are not quite romantically involved yet. In the English version, she has a
valley girl accent. She is also shown to be good friends with Hamtaro, as she confided in him her crush on Maxwell. ; :Voiced by:
Kōki Miyata (Japanese),
Noel Fisher (English), Michael Coleman (English) :Owned by Noel. Sandy's twin brother, who is often caught flirting with the other girl hamsters. As a result, he can be an annoyance to the other boy Ham-Hams, especially Boss, Howdy, and Dexter. Initially, Sandy and Stan were separated, after Noel (who had a crush on Hillary) offered to take care of one of her hamsters. He is often seen shaking his maracas or riding his skateboard. Stan seems to have a crush on Flora, the nurse hamster pet of the veterinarian, Dr. Lion. ; :Voiced by:

Paul Dobson (English) :Owned by Goldie. A Ham-Ham notorious for telling bad jokes, especially at inconvenient times. He speaks with a

Cathy Weseluck (English) :A mysterious hamster that Boss found in his hideaway (which would soon become the Clubhouse). It is unknown where he came from or how he found his way there. He is always
sleeping, but often utters some helpful and wise advice when the Ham-Hams are in need of it. Through uncanny streaks of luck, any bad situations he may end up in always seem to work themselves out for him; leaving him no worse than before. In the English version, he talks with a
lisp. His Japanese name is based on the word "neru" (寝る
to sleep), while his English name is based on the word "snooze". ; :Voiced by:
Chihiro Suzuki (Japanese),
Samuel Vincent (English) :Owned by Curtis. A refined hamster, who is quite smart. He has a crush on Pashmina, but often battles with his long-time friend, Howdy, for her affection. His Japanese name is a pun: Megane means "glasses" in reference to the tan markings of fur around his eyes that makes him look like he's wearing glasses. Coincidentally, his owner is an
optometrist. ; :Voiced by:
Ai Uchikawa (Japanese), Ellen Kennedy (English) :Owned by Kip and Sue. One of the younger Ham-Hams, Cappy loves hats. The two hats he most commonly wears are his green swimming cap, and the giant red saucepan that he usually hides under. While he loves his home, he does not like being spoiled, and looks up to Boss due to Boss's independence as a field hamster. Pashmina often tends to him when they are together. He has developed some sort of a rivalry with Stucky, especially when it comes to hide and seek. His Japanese name is based on the word "kaburu" (被る ''to wear/put something on one's head''), while his English name is based on the word "cap". ; :Voiced by: Yūko Saitō (Japanese),
Jillian Michaels (English) :Owned by Mimi. A Ham-Ham
