Helliton
From Tardis Wiki, the free Doctor Who reference
Heliton was a crewman in Earth forces during the Orion War. As an android sympathiser, he tampered with the intelligence reports, resulting in the deaths of the entire Planetary Assault Force on Orius Beta VIII.
He was tortured to death by Admiral Karen Brett to obtain the decoding frequency to the scanner sheath the Android Eighth Fleet was using to hide from and ambush any ships attempting to aid the ground forces. This information proved vital to the tactical victory over the Android fleet, which was located near Orius Beta V. (AUDIO: Scorpius)
