The XXXG-01ST Aqua Shenlong (Also Tornado Gundam) was introduced in the New Mobile Report Gundam Wing Perfect Album Bom-Bom Comic Variations.
An underwater-use version of the XXXG-01S Shenlong Gundam, it was a versatile unit that could operate both on land and in the water. It was equipped with powerful hydrojet thrusters in its backpack and shoulders and allowed the Aqua Shenlong greater maneuverability in water. Its main weapon was a hydrojet-powered dragon fang mounted on the right arm that could crush a battleship easily. Additionally, its left arm can separate into two standard dragon fangs that can function equally well on dry land or underwater.
