Lili, the daughter of Truman Zanotto, grand head of Psychonauts, is a fellow trainee at Whispering Rock Psychic Summer Camp, and has been so for a number of years prior to Razputin's temporary enlistment. She has a wealth of existing psychic experience, and loves nothing more than exciting adventures to stir up the otherwise quiet nature of the campgrounds. Although Lili is an excellent psychic, she's become bored and disillusioned from years of repetitive training, and believes the Psychonauts are 'just not what they used to be'.

From the very moment that Razputin walks (or drops, as the case may be) into the camp, Lili falls for the budding Psychonaut. However, her natural reluctance to throw herself at him prevents her from immediately revealing her affections. The two grow closer as they discover that they are sharing the same disturbing nightmares and begin to work to save Whispering Rock and the world. However, Lili is abducted, and Raz gives pursuit to save her. In the end of the game, they finally come together.
