Like all other Gyms in Paldea, the Medali Gym building itself is simply used for registering Gym challengers. The Gym Test requires the player to gather clues across Medali, and the Gym battle is conducted at the Treasure Eatery restaurant.
Gym Test
The Gym Test of the Medali Gym requires the challenger to figure out the secret menu item. At the start of the test, the player is given one clue for the secret menu item, while the other clues are scattered in various places throughout the town. Other Gym challengers can be found across Medali and will give hints to the player if defeated, which will help the player in finding the clues.
Once the player has figured out the secret menu item, they must report it to the waiter at the Treasure Eatery. If the player places the correct order, Larry will accept a battle against them.
The possible answers for the secret menu item are as follows (the correct answers are written in bold):
Like the other Paldean Gyms, there are Trainers present. Unlike those Gyms, however, the ones fought here are not local Gym Trainers, but other Naranja AcademyS/Uva AcademyV students who are also attempting to challenge Larry.
Medali Gym appeared in HZ059, where Liko, Roy, and Dot visited it for Dot's second Terastal Training test. While Larry was away from the Gym when the group visited it, they later found him at Treasure Eatery, where Larry formally introduced himself and agreed to battle Dot at a battlefield that was revealed to be located at the restaurant. During the test, Dot used her Tinkatink in battle for the first time and her Quaxly unexpectedly evolved into Quaxwell. Despite this, however, Dot ultimately lost the battle, but Larry still approved her performance and usage of Terastallization in a battle with two Pokémon, allowing Dot to pass the test.
Dudunsparce is Larry's third known Pokémon.It was used during Dot's Terastal Training test, where it faced both Quaxly and Tinkatink. It was able to gain the upper hand on Quaxly when it paralyzed him with Glare. It then battled Tinkatink before being recalled in favor of Staraptor after their attacks seemed evenly matched.
Staraptor is Larry's fourth known Pokémon. It was used to battle Tinkatink and Quaxly during Dot's Terastal Training test battle, where it was swapped in to replace of Dudunsparce and quickly defeated Tinkatink. Despite receiving major damage from Dot's newly evolved Quaxwell, it was still able to defeat him after Terastallizing while Quaxwell was immobilized by paralysis.
