Meer Campbell has a voice that sounds very similar to her idol's, Lacus Clyne, and she uses this to her advantage as she impersonates Lacus throughout the episodes. Reflecting this, both Meer Campbell and Lacus Clyne are voiced by Rie Tanaka in the Japanese version and by Chantal Strand in the English dub. Jillian Michaels provides the English singing voice of both as well.Her name means "lake" in Dutch, possibly reflecting her role in the story as her idol—Lacus's name also means lake but in Latin.

Meer is contacted by Chairman Gilbert Durandal, who asks her to pose as Lacus to enhance his political position. After she accepts the job, Meer's face is surgically altered to look identical to Lacus; however, tell-tale signs that reveal their own identities—their hairclips and attire.

Meer takes Lacus' image as a pop star further: singing more upbeat versions of her songs, more dancing, more revealing clothing, etc.

Realizing that Lacus has a political influence greater than his, Durandal uses Meer to gain support for his policies. Meer believes in Durandal's ideals, and is glad to further his agenda by impersonating Lacus. Meer's belief is that by impersonating Lacus, she will be loved by everyone. However, a few people can tell the difference; Athrun Zala, Kira Yamato, and most of the other major characters in the Three Ships Alliance easily know she is not the real Lacus, especially since Lacus has been living with most of the senior members of the Three Ships Alliance in Orb, and later onboard the Archangel. In The Edge (a manga series depicting Athrun's side of the story), Gilbert Durandal acknowledges to Athrun that Meer is an impostor.

Meer is flirty and tends to be very excitable, especially in Athrun's presence.

When she first meets Athrun, she introduces herself as Meer Campbell, and admits she is not Lacus Clyne. When Athrun attempts to convince her to escape Gibraltar with him, she refuses, claiming that she is Lacus and that she prefers to be Lacus. Later in the series, Meer insists to Athrun and Lacus herself that she is Lacus.
