M is for... Mercer

A headstrong young lieutenant assigned to the space station which was acting as prison to Davros, creator of the Daleks. Captured by escaped slave workers on Skaro, he had been brought to Earth to stand trial and had been sentenced to cryogenic suspension on this vessel in deep space. Mercer was angered by the way the station was run, with lax procedures and poor maintenance. Dr Styles warned him not to kick up a fuss. Others before him had tried and failed. Soon after his arrival, the station was attacked by a Dalek force, working in conjunction with mercenary Commander Lytton and his troopers. Most of the crew were killed by a toxic gas, but Mercer and Styles survived. Attempts to kill Davros failed due to the equipment failing, so they elected to blow up the station with him on board. Mercer joined forces with the Doctor's companion Turlough, after initially thinking him a Dalek agent. A man named Stien, who was a Dalek replicant, joined them. His mental conditioning was erratic, and his unreliability led to Mercer's death at the hands of one of Lytton's men.

Played by: Jim Findley. Appearances: Resurrection of the Daleks (1984).

• This story features surnames from earlier Dalek stories - Styles (Day of the Daleks) and Galloway (Death to the Daleks) - and Eric Saward opted to give Mercer the first name 'Tyler' in his novelisation of the story (as in a character from The Dalek Invasion of Earth).
