Harmony (エンジェルちゃん) is an angelic hamster who appears in Hamtaro: Ham-Ham Heartbreak and some of the Japanese episodes. Fighting for the power of love, she reunites separated couples and repairs broken friendships.
Harmony is a lovely and kind hamster. She makes it her mission to help others out, in the name of friendship and love. When hamsters' relationships enter a rough state, Harmony will be there to help settle things; shooting love arrows at the hamsters to restore their love. She is the arch-enemy of Spat; an evil, devilish hamster who attempts to destroy love and happiness.
She always says "tee hee" at the end of her sentences. When getting ready to use her magic (in the Japanese episodes), she says the phrase "Rabu Rabu Rabu Rin, Rabu Rin Rin!".
Harmony and Spat are always at odds with one another. While Spat sees her as his mortal enemy, Harmony tries her hardest to just get Spat to change his villainous ways. She seems to get tired of chasing Spat around, but she is very patient with him. When he does bad things, she encourages him to "just do good things". At the end of Hamtaro: Ham-Ham Heartbreak, Harmony turns Spat into an angel; possibly indicating that he eventually did turn to the "good side".
In Hamtaro: Ham-Ham Heartbreak, it is implied that Harmony may have a crush on Boss (and vice versa). When she was at the Clubhouse, she said she enjoyed it there very much, spending much time with Boss and teaching him her Ham-Chat words.
- In the Italian dub, she is called Lucina, which means "little light" or "fairy light".
- On the North American releases of the Hamtaro Official Trading Cards, Harmony's halo is removed; seemingly due to it implying loose religious context.
