Krell (22nd century)

Admiral Krell in 2154.

Krell was a Klingon Admiral who attempted to destroy Qu'Vat colony after it became infected with a Klingon augment virus, despite Phlox's assurances that he had developed a treatment. Krell became more receptive after Phlox beamed a sample of the virus onto the bridge of Krell's ship, infecting him and his crew. Phlox refused to give him the cure unless Krell powered down his weapons, which he did. (ENT: "Divergence")
