Aqua monsters represent water and liquid for the most part, if not ice in certain cases, such as "Mobius the Frost Monarch". They may also represent aquatic or amphibious creatures that do not fall under the category of Fish or Sea Serpent. In the same respect, most Aqua-Type monsters are WATER-Attribute monsters. Aqua-Type effects are varied, but many of the best focus on hand control.

The powerful Archetype of Frog monsters fall into this category.

Other notable Aqua-Type monsters include: "Tribe-Infecting Virus", "Cloudian - Eye of the Typhoon", "Penguin Soldier", "Abyss Soldier", "Servant of Catabolism", and "Yomi Ship".

The monsters that belong to this Type also gain a boost from "Umi", "Power of Kaishin", "Maiden of the Aqua" and "Wetlands".
