Lassar

Mr Finch (Brother Lassar) was a Krillitane who took over a Deffry Vale High School in order to crack the Skasis Paradigm which would make both he and his brothers "gods". He was a very sinister alien and liked eating children for his lunch. Eventually, his plan was foiled and Mr Finch perished along with the other Krillitane's when K9 blew up the school.

He was protrayed by Anthony Stewart Head.
