Zebesian (Aqua)[1] are only found in Metroid Fusion. They were the result of an X Parasite containing Skultera DNA combining with a Zebesian, giving the Zebesian the ability to swim, as well as a pair of fins and a mermaid-like tail. When this enemy does not sense an enemy, it will swim sluggishly, but after detecting Samus Aran's presence, they will immediately charge right at her. They fire short, red blasts compared to the green shots fired by normal Zebesian. The mutation makes them better suited to water than normal Zebesians, but also decreases their strength.
