Submarine Explorer 1

The Submarine Explorer 1 (Japanese: かいえん Kaien No. 1) is a submarine built at Stern's Shipyard in Slateport City.

Team MagmaROR or Team AquaSEAS twice try to steal the Devon Parts, which are parts of the submarine, before the submarine can be built.

After the submarine is completed, Stern reveals that its purpose is to explore the Seafloor Cavern, an underwater cavern on Route 128. However, Team MagmaROR or Team AquaSEAS end up stealing the finished product in Slateport City and taking it to the cavern themselves.

In Generation III, the only time the submarine is visible is when it is parked in the entrance of the Seafloor Cavern while the villainous team is inside. In Generation VI, the submarine gets more screentime, being showcased during the theft in Slateport, the preparations at Team Magma HideoutOR or Team Aqua HideoutAS, and parking inside the Seafloor Cavern. In these games, the submarine is also modified by the villainous team after it is stolen. It is modeled to look like a CameruptOR or SharpedoAS, each team's signature Pokémon, and is equipped with a special drill designed to break the seal blocking the entrance to the Seafloor Cavern.

Inside the Seafloor Cavern, one of the grunts remarks that the submarine is "brutal as a ride" because of its small size. Judging by the number of villainous team members in the Seafloor Cavern, the submarine is able to fit at least sevenE people. The submarine is not seen again after the player clears the villainous team from the Seafloor Cavern.

Pokémon Generations

The Submarine Explorer 1 first appeared in The Vision, where it was seen at Team Magma Hideout in its modified state. Maxie, Tabitha, and a division of Team Magma Grunts boarded the submarine and headed for the Seafloor Cavern.

The submarine reappeared, this time in its Alpha Sapphire guise, in The Cavern. Team Aqua used it to exit the Seafloor Cavern after Archie had awakened Primal Kyogre. Once they surfaced, Archie was shocked to discover that the devastation Kyogre was causing was far beyond anything that he had planned for.

Ruby & Sapphire arc

The Submarine Explorer 1 (called S.S. Kaien 1 in the Chuang Yi translation) first appeared in Slugging It Out With Slugma II, where it was stolen by Team Magma in Slateport City. Ruby was caught inside the submarine during the theft, but he managed to get away by using an onboard escape pod. With the submarine's key component having been stolen from Mr. Stone by Team Aqua in Mowing Down Ludicolo, the two teams agreed on a temporary truce in Walrein and Camerupt in order to combine their resources. When the key component was combined with the submarine, it became able to reach greater depths than usual, allowing both teams to safely reach the Seafloor Cavern together in The Beginning of the End with Kyogre & Groudon I.

In Very Vexing Volbeat, Archie sent the submarine to dive to the ocean's depths on autopilot after trapping Amber and Tabitha inside it and removing the key component. As a result, the submarine began to buckle under the high pressure of the deep sea, and was ultimately destroyed in No Armaldo Is an Island, with wreckage floating to the surface while Amber and Tabitha were saved by Blaise.

Omega Ruby & Alpha Sapphire arc

In Kyogre Returns, two submarines, each based on one of Submarine Explorer 1's Generation VI post-upgrade designs, appeared under the ownerships of Neo Team Aqua and Neo Team Magma, respectively. The Admins of the teams used them to travel to Mossdeep City.
