Mister Dread Mister Dread was a member of the Men in Black and the leader of three designated to guard the vault . Dread was part of a mission of the Alliance of Shades to stop human s realising the truth about the Grey alien s . He tracked down the Tenth Doctor , Cassie and Jimmy , but was damaged by Night Eagle . He managed to rebuild himself and retrieve the ionic fusion bar , bringing it back to Dreamland , where he was apparently destroyed by the sonic screwdriver . ( TV : " Dreamland " ) In 1972 the Alliance of Shades was disbanded and the majority of his kind were decommissioned as a result . Despite this , the Alliance were unable to remove their hyperdimensional vault connected to St Jude ' s Hospital , where they stored their confiscated alien equipment . In light of this , Dread and two androids were re - assigned to guard the vault indefinitely . One of the activation disks for the vault was left in the care of Ocean Waters , while the other found its way off - planet . In 2010 , Dread and two other agents were located in St Jude ' s Hospital . When Androvax ( in the body of a human teenage girl ) entered the Hospital , Dread and the others were awoken by the perimeter alarms and chased him off . He and the other agents stopped Sarah Jane Smith after Androvax sent her and the others there to free his people . When he discovered that Sarah Jane had taken a clipping of Ocean Waters ' s abduction by aliens , he and the other agents attacked Ocean ' s house . Androvax managed to escape in Gita Chandra ' s body ; Dread followed him , commandeering a van to the vault . He tried to use Gita and Rani Chandra as bait but was ambushed by Clyde and put back in his box , only to be activated soon after by Sarah Jane so he could use his power supply to transmat the Veil ship into space , saving Earth . Dread had used 450 years of power through that act , but since the vault had been sealed with Androvax ' s departure he had no further purpose and decided to deactivate himself . As suggested by Sarah Jane , he used some of his remaining power to wipe Gita ' s mind of her alien encounters before retiring . ( TV : " The Vault of Secrets " ) Personality . Like most Men in Black , Dread ' s personality was cold and aloof . Dread claimed that the Alliance programmed him and the others without emotion because they believed they would make the androids less efficient in their duties , though this lack of emotion contributed to most of them being deactivated by the 1970s . Despite this , Dread displayed a certain level of pride in himself , claiming he was one of the Alliance ' s more successful and efficient models . Even though he claimed he had no sense of humour , Dread appeared to have developed a dry sense of humour . This was evident when Sarah Jane damaged his car and he was bothered by another driver . The driver said he should have found a new vehicle . Smirking , Dread told the man he would take the man ' s van and ripped the door off its hinges , frightening the man off . Dread also displayed a level of ingenuity and cunning that seemed unique to him . Using his mindwiping abilities on Ocean , he also hid the second lock to the vault with her , convincing her that it was a piece of jewellery and conditioning her mind so she would not discard it . ( TV : " The Vault of Secrets " ) Weaponry . He had the ability to remove his hand and produce a blaster , which shot green laser blasts . An organic being would be incinerated if the laser hit a living target . Abilities . Mister Dread had a Neuron - X Series 5 processor , a tritanic endoskeleton and a power cell that was capable of lasting for 500 years . Mister Dread was also able to mind wipe those who saw alien activity . This mind wipe , however , could also leave traces of Dread himself . As an android , He also had superhuman strength , capable of ripping off a lorry door with ease . ( TV : " The Vault of Secrets " ) Although vulnerable to the Tenth Doctor ' s sonic screwdriver in 1958 , ( TV : " Dreamland " ) by 2010 he was immune to the effects of Sarah Jane Smith ' s sonic lipstick while activated . The sonic lipstick was , however , capable of force - activating Mister Dread . ( TV : " The Vault of Secrets " ) Behind the scenes . In " Dreamland " , Mr Dread was apparently destroyed , which possibly contradicts his later appearance in " The Vault of Secrets " . However , Peter Guinness supplied his voice for the character in the former , computer animated , story and Angus Wright played him in the later story , which would suggest that they were two different versions of Mister Dread .
