Mr Clever
Mr Clever was a Cyber-Planner that tried to overtake the Eleventh Doctor's mind in an attempt to resurrect the Cybermen. Unlike most Cybermen, it displayed a distinct personality and emotional responses, likely due to being influenced by the Doctor's personality. The alternate ego also controlled parts of the body such as the Doctor's left arm. The cyber planner also shared a corner of the Doctor's brain that was blue tinted, and evil looking.He seemed interested in humans, time lords and displayed emotional manipulation and intelligence usually unattributed to Cybermen.Mr clever also shared the slightly barmy attitude of the Doctor, such as leaping onto tables and whirling on the spot.It was created when the Eleventh Doctor was infected by Webley.
