* She is the only character to ever replace the [[narrator]] at the start of an episode. She did so from ''[[SM045|Now You See Them, Now You Don't!]]'' to ''[[SM055|The Professors' New Adventure!]]'' (apart from ''[[SM048|Night of a Thousand Poses!]]'').
* Lillie is the only student of Professor Kukui to obtain her [[Z-Ring]] and her first [[Z-Crystal]] in two different episodes.
