The Mermen are a group of Seekers that reside in the Casterwill compound of Atlantis. They are the Test of Prowess for those who wish to enter the compound, the former resting place of the Amulet of Will.
The origins of the Mermen are unclear. They are the second test to enter the Casterwill compound in Atlantis. Eathon Lambert never made it to their test, but his son, Lok Lambert, as well as Dante Vale, Sophie Casterwill, and Zhalia Moon managed to enter Atlantis and pass the Mermen's test.
The Mermen are capable of summoning equivalent, water-based Titans to those summoned by a Seeker within their test. This power, however, is useless against a Legendary Titan as they are one of a kind and have no equivalent Titans. The Mermen also have a host of spells at their disposal. Although being the guards of a Casterwill compound, Casterwill spells do not appear to be in their repertoire.
