Tonmi Kristian "Otus" Lillman (3 June 1973 - 13 February 2012) was Lordi's drummer from October 26th 2010 until his death. He was the replacement for Kita.

Otus tragically passed away in 2012 from a bout with illness. He was aged 38 at the time of his death. In order to compensate for the death of Otus,Lordi hired a temporary drummer. The new drummer's identity was unknown,and he was just called "The Drummer". It was later revealed that "The Drummer" was actually Jimmy Hammer of the Finnish band Ironcross.
