Rotom Pokédex

The Rotom Pokédex (Japanese: ロトム Rotom illustrated encyclopedia), also known as the Rotom Dex, is an electronic device found in Alola. It is a Pokédex that is enhanced after being possessed by a. It appears in Pokémon Sun, Moon, Ultra Sun, and Ultra Moon. This special Pokédex is said to be rare, even in the Alola region. While inside the Pokédex, can speak with the player. It is given to the player by Professor Kukui.

In addition to functioning as a regular Pokédex, the Rotom Pokédex also has other features for the player to use.

Functions
In Pokémon Sun and Moon, the Rotom Pokédex appears on the bottom screen, displaying a map of the area the player is currently in. By tapping the screen, the player can access a variety of functions:
 * When the player taps the center of the map, Rotom repeats its most recent suggestion on where to go next.
 * When the player taps the map outside the center, the full map function opens, acting in a similar way to the Town Map in previous games.
 * When the player taps the black bridge between Rotom's eyes, the Pokédex function opens.
 * When the player taps either of Rotom's eyes or on the red part of its body, Rotom will shake and react in a variety of ways.

In Pokémon Ultra Sun and Ultra Moon, the Rotom Pokédex gains more features, upgrades, and different personalities depending on how the player responds to the Rotom Dex.
 * The player can bond with the Rotom Pokédex in order to unlock new features such as the Rotom Powers and Z-Rotom Power.
 * The Rotom Dex gains its own form of Affection as the player starts talking to it or interacting, which gains a heart every time that happens.
 * Every ten minutes, the Rotom Dex will get a sad look. Tapping it will cause it to react and give it a heart and may ready the Roto Loto, or it may ask the player questions, answering these questions give Rotom a heart and may ready the Roto Loto. Rotom will also ask questions at certain story intervals, and upon reaching Poni Island every interaction that produces a heart will guarantee the readying of the Roto Loto.
 * Taking a photo when prompted by Rotom following the evolution of a Pokémon will ready Roto Loto, and doing things after becoming Champion such as surfing on Mantine has a chance of readying Roto Loto.
 * Rotom Dex can give the player a nickname depending on their choice, examples are Roto-(first character in player's name), Roto Jr. or Master.
 * The personality of the Rotom Dex can be influenced in three different ways, defeating many Pokémon will result in Rotom having an aggressive demeanor, using Pokémon Refresh often will give Rotom a more playful personality, and finally visiting the Pokémon Centers a lot will make Rotom more easy going.
 * Rotom Dex can give the player bits of information about game features, with the set of advice changing depending how much the player responds to the Rotom Dex.

Pokédex
The Rotom Pokédex's primary function is a fully featured Pokédex. The player can browse and search Pokémon species, view data about them, and look up their habitats. The Pokédex can also produce QR Codes for the QR Scanner for most registered Pokémon. In Pokémon Ultra Sun and Ultra Moon, a Pokémon that can only be encountered in an SOS Battle will have a picture of an Adrenaline Orb next to its location markers when the map is zoomed in.

Map
When the Rotom Pokédex is idle, the screen usually shows a map. In this view, the map stays centered on the player's immediate area. The player's location is marked by a smiley face icon, with an arrow indicating the direction the player is facing. If the player is inside a building or certain locations (such as Ten Carat Hill), however, the map will remain stationary no matter where the player moves and there is no directional arrow. During the main story, a red flag may also appear, indicating a place the player is supposed to go.

If the player taps the map, the screen's view broadens to show a larger map akin to Town Maps in other games. In this broader view, the top screen shows an overview of the whole Alola region, while the bottom screen focuses on an individual island. If the player moves the map's cursor over different areas on the island, the top screen will show a snapshot of the area, a description of the area, and a list of landmarks within it. The player can scroll between the islands using the L and R Buttons and can zoom in using the Y Button. This view also marks the location of any Pokémon Center the player has visited with an icon.

The broad map is also used when the player uses Charizard Glide. In this mode, all places that the player can fly to are marked by wing icons.

The island maps (from the lower screen of the broad map) are also used when the player views a Pokémon's habitat from its Pokédex entry.

Poké Finder
The Poké Finder (Japanese: ポケファインダー Poké Finder) function allows players to take pictures of Pokémon in locations where the icon on the player's bottom screen turns into that of a camera. It can be activated by pressing the R button or tapping the camera icon in those select locations. Pictures are then evaluated with a "Thumbs-Up" score.

Upgrades
Upon taking pictures, the player is awarded with a "Thumbs-up" score, which is then added to the total number of "Thumbs-Ups" the player has earned over time. As the total number increases, new versions of the Poké Finder can be unlocked as follows:
 * Version 1: Default version.
 * Version 2: Unlocks at 1,500 Thumbs-Up. Adds the ability to zoom.
 * Version 3: Unlocks at 10,000 Thumbs-Up. Adds additional zoom.
 * Version 4: Unlocks at 100,000 Thumbs-Up. Adds maximum zoom.
 * Version 5: Unlocks at 1,500,000 Thumbs-Up. Adds the ability to call Pokémon over to the player. A stamp is added to the player's Passport.

Photo Locations
Pictures can only be taken at specific locations, each of which features its own set of available Pokémon. The Pokémon that can be encountered vary with the time of day.

Roto Loto
In, this feature is unlocked after visiting the Pokémon Center on. Roto Loto allows the player to obtain items called Rotom Powers, which can be used to provide boosts similar to the Pass Powers from Generation V and O-Powers from Generation VI.

The feature can be activated by tapping on Rotom's eyes once it starts to glow gold, which can occur at random times between 10-20 minute intervals. Its eyes can also glow by tapping on Rotom if it has a sad look on its face. Once the player reaches Poni Island, the player can also activate Roto Loto by interacting with Rotom or answering its questions. After becoming the Champion, the Rotom Dex will activate Roto Loto if certain requests are fulfilled, such as after Mantine Surfing or Ultra Warp Riding.

Rotom will automatically use several Rotom Powers during the course of the story - Roto Experience when arriving at Melemele Meadow to retrieve Nebby, Roto Hatch after obtaining the Egg at Paniola Ranch, and Roto Prize Money when first passing through.

Z-Rotom Power
In, the Rotom Pokédex gains this ability from when the player reaches maximum affection with Rotom. When a Rotom Power is used during or outside of battle, the Rotom Dex will assist the player by allowing a Z-Move to be used again for a second time during the battle.

In the anime


received an Alola Pokédex from Professor Kukui in The Guardian's Challenge!. It was empty until Loading the Dex!, where Kukui completed the Pokédex by having a Rotom enter the device, turning Rotom into what it calls the Pokédex Rotom version (Japanese: ロトムポケデックスフォルム Rotom Pokédex Forme). It has since registered Ash as its user and follows him around the region.

In the Pokémon Adventures manga
The Rotom Pokédex debuted in The Grand Entrance and Delivery Boy Sun. Originally, it was a regular Rotom that Professor Kukui requested to receive from a region outside of Alola so that he may use it to fuse with one of his Pokédexes. Due to this particular Rotom having a weak body, it was unable to be transferred electronically, so was given the task of delivering Rotom to Professor Kukui while also using her pharmaceutical skills to keep it healthy along the way.

After Moon successfully delivered Rotom, Professor Kukui decided to have it enter 's empty Pokédex. Due to Sun's mishandling of the Pokédex, Rotom refused to enter it and ran away in disgust. Angered by this, Professor Kukui forced Sun to retrieve Rotom while he attempted to clean the dirty Pokédex.

Later, it was revealed that Professor Kukui had a spare Pokédex, which he gave to Moon. This Pokédex was the one that Rotom decided to enter, becoming the Rotom Pokédex in the process.

Moon later traveled to Lush Jungle with Mallow to find a Mirage Berry. There, they found in battle with a. Not knowing anything about the Ultra Beast, Rotom went up to Xurkitree to try and record data on it. Xurkitree retaliated by shooting Rotom with a powerful Electric attack, forcing it to fall to the ground and shut down. When Rotom later reactivated itself, it could only utter one word: "".

While traveling from Akala Island to Ula'ula Island, Professor Kukui's yacht was attacked by a wild. Though Sun managed to defeat the Pokémon, he, Lillie, and Rotom ended up separated from Moon and the others. When doing his second trial at the site of the former Thrifty Megamart, Sun was given the task of taking a photo of the Totem Pokémon that lived inside. Shortly after entering the area, Sun and Lillie were attacked by the Totem Pokémon, a, which destroyed the camera Acerola gave him for the trial. While Sun had battle Mimikyu, Rotom revealed itself and let Sun use its Poké Finder function to replace the broken camera.

As the battle went on, Rotom translated Mimikyu's speech to reveal that it was angry at Sun for insulting its ragged appearance, as other humans had did in the past. After encouraging Mimikyu to find companions who would appreciate it despite how it looked, Sun added Mimikyu to his team and gave it the nickname Franc. Rotom took a picture of Sun and Franc together and emailed it to Acerola, successfully completing the trial. Afterward, Sun thanked Rotom for his help and suggested it join his team, which Rotom rejected.

By the time Moon arrived in Ultra Space, Rotom had rejoined her. Using the powers of the Pokédex, it was able to sense a, who would be able to take them all back to their world. Upon finding it, they discovered the Ultra Recon Squad members Zossie and Dulse riding it.

In the TCG


Rotom Dex was introduced as an TCG Item card in the Pokémon Trading Card Game during the English Sun & Moon Series (the Japanese Sun & Moon Era). It was first released in the TCG Collection Sun expansion before debuting in English in the TCG Sun & Moon expansion, with an illustration by 5ban Graphics. It was also released as a TCG Full Art card in both expansions, with an illustration also by 5ban Graphics. Rotom Dex allows the player to shuffle their Prize cards into their deck. The player then take the same amount of remaining Prize cards they have left from the top of their deck and put them face down as their new Prize cards.

Trivia

 * The Rotom Pokédex is the only Pokédex without the ability to view information about all Pokémon known as of that time (Generation VII), as it lacks information on the 403 Pokémon not in the Alola Pokédex and cannot receive a National Dex upgrade by any means.
 * Despite being a Rotom, the Rotom Pokédex is unable to view information about Rotom.
 * In Pokémon Sun and Moon, Samson Oak mentions that the Rotom Pokédex was at least partially invented by a "young fellow from Kalos", which could be referring to Clemont. This is further supported by the Pokémon Adventures, wherein Professor Kukui reveals that the Rotom Pokédex was developed by "Kalos's famous genius inventor".
