Q-Bee is the leader of the Soul Bee race, a race that eats souls to live. Q-Bee stands for Queen Bee, which is her title, not her name. Their race lived in the lands of the Dohma family. But during the time when Jedah was dead, her home began to crumble and her race was on the verge of dying out. When Jedah was revived and created the Majigen, she noticed the vast amount of souls in the new dimension. She headed towards the Majigen to gather souls to satisfy her Soul Bee's hunger and to satisfy her own hunger as well.
Overall, Q-Bee is an easy-to-play six-button character with a few quirks that makes them a bit less typical than average. They are capable of dashing in midair, and have a set of attacks where they fly to the corner of the screen before lunging with their stinger out, and is also capable of entering a mode of extended flight, which is ironic considering their moveset is actually rather lacking in the air, and much more vulnerable than their moveset on the ground.
Their AI is somewhat stronger than normal, and while a bit slow to react at times, is capable of some fairly clever and dangerous techniques involving a mix of all of the character's techniques.
