Bouncer (Robot)
From Tardis Wiki, the free Doctor Who reference
A bouncer worked for the S.R.S. and guarded the entrance to their meetings. When the Fourth Doctor arrived at a meeting without a pass, the bouncer advanced on the Doctor, but the Doctor tripped him with his scarf. When the bouncer recovered, he apprehended the Doctor.
He was later present at the S.R.S. bunker and tied up Harry Sullivan and Sarah Jane Smith.
He was later arrested when the S.R.S. was broken up by UNIT. (TV: Robot)
