Category 3 Attacker-class Siren-type

The Category 3 Attacker-class Siren-type Machina is an uncommon combatant characterized by their shield array and main role of underwater combat, as well as their bodies being adapted to aquatic movement with strong, fishlike tails replacing their legs. They move very quickly and with great agility underwater, often aided by electromagnetic water propulsion systems. Many of these Machina are able to levitate across solid ground, where their propulsion systems help them have some rudimentary ability to move around above water.
