Lulach appears to have been a weak king, as his nicknames suggest, and ruled only for a few months before being assassinated and usurped by Malcolm III.

However, it is also plausible his nicknames are the results of negative propaganda, and were established as part of a smear campaign by Malcolm III.

Lulach is also a character in David Greig's play Dunsinane where he is hunted by the English soldiers as a threat to peace in Malcolm's Scotland.

Lulach McPritchett in Modern Family, a Comedy series, is a Scottish warrior and ancestor of Jay Pritchett.

Lulach appears in a 2024 adaptation of Shakespeare's play called Gruoch and Macbeth: A Screenplay by Graham J. Howard.
