Ericson

Ericson (PROSE: Doctor Who and the Claws of Axos) was a technician at the Nuton Power Complex. He took charge of the complex after Hardiman's death. He attended a briefing on the threat posed by Axos with the Third Doctor, Jo, the Brigadier, Captain Yates, Sergeant Benton and Bill Filer, at which he agreed to clear the computers for the Doctor's use.

When the Axons attacked the complex, Ericson took refuge with the UNIT personnel in the reactor room and warned the Brigadier that the damage the Axons had done to the particle accelerator would make it explode. After the Axons were sucked into a time loop, Ericson reiterated the explosion was still imminent and left the room with the others when the Brigadier ordered an evacuation. (TV: The Claws of Axos)
