MerQueen is a very large Mer Creature and one of the minor antagonists in Primeval. She is a large red Mer Creature from the Future where she is the leader of the Mer Creatures. She came out of an anomaly and she attacked Abby Maitland and Connor Temple tries to rescue Abby, but Connor gets swapped by the MerQueen (the wilhelm scream can be heard). The MerQueen captures Abby and takes her to the Future. At the Future, Connor tries to help Abby, but the MerQueen arrives and drives away her Mer Creature minions. After Abby was rescued, the MerQueen climbs to kill Connor and Abby, but Nick and Stephen get their guns and shoot at the MerQueen and blood comes out of her, killing her instantly.
