Lego Aquazone

Lego Aquazone (stylized as LEGO Aquazone) was a Lego theme that was launched by The Lego Group in 1995 and discontinued in 1998. It centred on undersea miners and their enemies searching for crystals. It consisted of submarine vehicles and aquatic animals, with minifigures designed for submarine adventures.

Overview
Aquazone was a Lego product line that focused on undersea adventures. It launched in 1995 with two sub-themes named Aquanauts and Aquasharks, which were released simultaneously. This was followed by the release of three additional sub-themes: Aquaraiders in 1997, Hydronauts in 1998 and Stingrays in 1998. Aqua Raiders was launched later in 2007 as a standalone theme.

Aquanauts (1995–1996)
The Aquanauts were the heroes of this sub-theme, which launched in 1995 and continued production until 1996. They were defined as a group of undersea miners. The backstory of the theme focused on the Aquanauts exploring the ocean in search of crystals to investigate their properties. Their base was called the Neptune Discovery Lab. They also used underwater vehicles, such as the Crystal Explorer Sub and the Crystal Crawler to do their work.

Aquasharks (1995–1996, 1998)
The Aquasharks sub-theme was launched alongside Aquanauts in 1995 and continued until 1998. The Aquasharks were described as a group of scuba-diving bandits that attempted to steal the crystals. They used a variety of underwater vehicles, including the Spy Shark and Deep Sea Predator, which were designed to resemble sharks. The Aquasharks hid their stolen crystals in a cave instead of a base.

In 1997, the third sub-theme was launched called Aquaraiders. This sub-theme only released three toy sets. The Aquaraiders were designed as a group that searched the ocean floor looking for the crystals with their Scavenger and collecting them with the Aqua Dozer. Their ships were mainly designed with a green and black colour scheme.
