Spat is an evil and sinister hamster who fights with Harmony and tries to ruin love for all hamsters. He enjoys sowing discord and heartbreak in otherwise-happy hamster friendships and couples. He is able to use a little bit of magic, as he can fly and shapeshift into other hamsters. However, most of his power comes from being able to easily manipulate others. Spat is very childish and petty. If his plan doesn't work the way he wanted it to or he can't have something, he often throws tantrums.
