Aneel was a Kreel delegate sent to negotiate with the Klingon Empire regarding a recent supply of advanced weapons that the Kreel had discovered.

Although apparently willing to attend the negotiations on the Enterprise, Aneel swiftly revealed his true colours when he tricked the dying civilian passenger Jaan Devin into assisting him in gaining access to the ship's armoury in exchange for an alleged cure for his illness, his crew subsequently stealing various phasers for later use in a fight with the Klingons. However, his attempt to take the Enterprise was quickly undone, his mutiny ending when his body was partly thrown into an active transporter beam while he fought with Worf, resulting in his head and shoulders being sent down to the planet below while the rest of him remained on the Enterprise.
