Aquaman

Aquaman's powers and abilities

Water Body - Ramon can freely turn into Aquaman at any time he wants, assuming a liquid form. While he is like this he is invulnerable to almost all physical damage (as it passes right through him) and can increase his mass by absorbing water around himself.

Water Control - Aquaman can control all forms of water around him, whether it be creating massive water columns, creating a layer of fog to hide his approach or to blasting water from his finger tips. He is especially talented with the latter power, being able to expertly adjust its power from just knocking someone around to cutting through steel. In addition, he can propel himself at massively high speeds by rapidly releasing and reabsorbing water.

Danger Sense - Ramon has a powerful, if vague, danger sense that allows him time to transform into Aquaman if he's in any danger.

Aquaman's weaknesses

Dehydration - Excessive heat can cause Aquaman to rapidly lose mass as the water making up his body evaporates.

Tight Spaces - Despite possessing a liquid body, Aquaman cannot pass through areas that would be too small for his normal physical form, such as gaps in fences and the like.
