Spat (デビハムくん, Debihamu-kun/Devi-hamu-kun) is a game-only character in America from Hamtaro: Ham-Ham Heartbreak. He is commonly known for his tan light-gray and black fur, his devil costume, and saying "pfpth" (as an interjection, he constantly ends his sentences with "debi",in the Japanese dialogue). Strangely, he is only noticed by Bijou when he says "pfpth".
Spat is an evil and sinister hamster in a devil costume, who fights with Harmony and tries to ruin love for all hamsters. He never made an appearance in the English TV series; but made an appearance in Hamtaro: Ham-Ham Heartbreak (video game) as the main villain. In the Japanese version, Spat appears from time to time with different evil plots. Just as in Ham-Ham Heartbreak, the Ham-Hams always thwart his plans. He also blushed at Harmony in the anime meaning he may like her, and that he's just being childish about love. In the anime as well, he flies much better than before. He also gets magical powers, like blue lighting/sparks, possessing hamsters with skulls, and making things move with a blue glow around the object. He comes with different plots just as in Hamtaro Ham-Ham Heartbreak. Later on in the Hamu Hamu Paradichu series, he doesn't use skulls to possess hamsters. Instead he shocks them which makes the hamsters possessed, and he also has the ability to disguise himself into another hamster.
Spat is very known to have a hatred of love; he can break the love physically and mentally, for example, telling lies, causing a fight, kidnapping someone to make his/her friend to get worried and even creating fake love letters to make someone become jealous. He hates love so much because it sickens him; when his devil costume turn into a angel costume, he becomes disgusted and embarrassed, he seems to not have a fear of ghosts, Spat as an angel in Ham-Ham HeartbreakAdded by Phineas and Perry Fan as he thinks ghosts are like a anti-love being, however, as he's a hamster he also has a fear of cats. He enjoys sadness, mischief, jealousy, fights, and fears. Spat sometimes can make threats, like he threatened Hamtaro and Bijou, for trying to stop him, so he made the super coaster run at top speed, sending Sandy and her brother Stan flying everywhere. He also has the habit to provoke his enemies by making grimace.He may have some kindness in his personality, because when he kidnapped a hamster girl in Ham-Ham Heartbreak, he gave her a TV to watch and many comforts, showing that he somewhat cared for her feelings.
