Nightmare LiAnn is somewhat similar to LiAnn, but they have their differences. Nightmare LiAnn is immensly evil, unlike LiAnn. LiAnn entered the Nightmare Dimension through the Artificial Rift-Portal Transporter, a dimension-hopping device developed by the Irken Empire (and engineered by conquered Vortian scientists). She stumbled upon Nightmare LiAnn, and a very unfortunate incident occured, after which LiAnn no longer likes carrots.
