Dragon Ball Wiki

Monster Island (モンスターアイランド Monsutā Airando) is a place on Earth where numerous animals and rare creatures live, including Cell Juniors and Minotauruses.


After quitting work at a royal nature park, Android 17 moved to Monster Island.

This island is recurringly the goal of poachers who usually go in search of the legendary and unique surviving Minotaurus with the aim of snatching their horns of great value, but all these attempts are thwarted by 17, who works on the island as a Monster Island Ranger (MIR). The Dragon Ball Super manga shows that the seven Cell Jrs. reside on the island, which Android 17 has tamed so they don't attack the rangers.

In the anime, this ecological reserve was the objective of the Galactic Poachers, who, with their ship, took all the animals of the island, including the Minotaurus, but the plans of this criminal gang were foiled by Goku and 17.

Later, the island would be under the protection of Goten, Trunks and Marron in the absence of 17 for his competition in the Tournament of Power until it ended. While protecting the island, Goten and Trunks encountered the Cell Jr's, whom Android 17 had forgotten to tell them about. Fortunately, Goten and Trunks were wearing MIR uniforms which they eventually noticed while fighting them, causing the Cell Jrs. to to stop fighting.

Android 17's wife was a ranger here prior to marrying 17.[1] In the manga, the Cell Juniors living on the island consider the Rangers as allies as they have been tamed by Android 17. Goten and Trunks briefly work as Rangers during the Tournament of Power with Android 17's niece Marron staying with them on the island as a guest. In the manga, Goten and Trunks wear Ranger uniforms like Android 17's while defending the island.
