Lassar


 * "Lucas Finch" redirects here. For the Gizou who impersonated Lassar, also known as "Lucas Finch," see Lau'Tan

Brother Lassar was a Krillitane who, under the name Lucas Finch, took over Deffry Vale High School in order to crack the Skasis Paradigm, which would make both him and his brothers "gods". He ate at least one school child and several of human staff of Deffry Vale along with his "brothers". Lassar tempted the Tenth Doctor with the Paradigm, insisting on "the changes that could be made if this power was used for good"; that he could bring back Perganon, Ascinta or the Time Lords. Sarah Jane Smith stopped the Doctor and reminded him to "move forward". The Doctor declined Lassar's offer and ran. Eventually, Lassar's plan was foiled and he was believed to have perished along with the other Krillitanes when K9 Mark III blew up a vat of Krillitane oil, destroying both the Krillitanes and the school. (TV: School Reunion)

It was thought that Lassar had survived the blast, permanently adopted human form and the name Lucas Finch, and served as prosecutor when the Tenth Doctor was put on trial by the Shadow Proclamation. "Finch" was revealed to be Lau'Tan, a Gizou in disguise, hoping to use Lassar's form to manipulate the Doctor, the Krillitanes, and the Shadow Proclamation. (COMIC: Fugitive)

Behind the scenes

 * Finch's first name was not given onscreen, only on the Deffry Vale School website. According to an on-line interview with Head, Finch's original name in the script was "Hector", but this had to be changed when a check found a real headmaster named "Hector Finch". However, Finch's name is given as Hector in Doctor Who: The Encyclopedia.
 * Near the climax when K-9 is attacking the Krillitanes, Mr.Finch orders his men to "Stop that shooty-laser dog thing" that manner of speaking was a running gag from the show Buffy The Vampire Slayer which also starred Anthony Head.
