A holographic nightclub singer created by Vic Fontaine in 2374 in the image of Kira Nerys, so that Odo can practise being at ease with her.
Lola Chrystal appears in the Deep Space Nine episode His Way. When Odo turns to the holographic lounge singer Vic Fontaine for advice about his feelings for Kira, Vic decides that what the constable needs is rehearsal, and builds a character for the purpose.
Lola is a sultry singer of the early 1960s who looks exactly like Kira and performs Fever in Vic's lounge. Odo is taken with her at first, then finds the whole thing hollow, because she has Kira's face and nothing else of her.
Vic concludes that only the real woman will do. He tricks both Kira and Odo into a dinner in the holosuite, each believing the other knows the truth, which leads to their first kiss on the Promenade.
