UNTOUCHED (ORIGINAL)

Untouched means you will obtain the Pokémon in its original build and stats, as though you have received it directly from the event distribution in its rawest form with all the nitty-gritty details as shown in the photo with the event information above. 

CUSTOMIZED

• Pokémon Level: The level cannot be below the distribution level. It can only be modified higher (as Pokémon can be levelled up). For example, if the event Pokémon was distributed as Level 50, you can customize it to be Level 51 or 100, or any level in between, but not below 50. 
• Shininess: If the event Pokémon was released as shiny, it cannot be customized to be non-shiny, as well as modifying a non-shiny event Pokémon to be shiny, unless the event distribution clearly stated that the event Pokémon can be obtained in either shiny or non-shiny form.
• Nature: Only when the event Pokémon was released with random Nature can you choose for any Nature that you want. Some event Pokémon has permanent Nature and cannot be altered.
• Individual Values (IVs): Most event Pokémon come with random IVs, and that's when you can change them to your liking. When they are released with fixed IVs it will be mentioned in the description above.
• Effort Values (EVs) or Awakening Values (AVs) in Let's Go versions: Most event Pokémon come with 0 EVs or EVs in all stats, and that's when you can change them to your liking. When they are released with fixed EVs/AVs it will be mentioned in the description above. Please note that the EVs can only be up to 510 EVs in total with max EV in two stats only up to 252. In Let's Go game versions, all stats can have 252 Awakening Values (AVs).
• Moves: All the moves that come with the event Pokémon have their PPs (Power Points) non-maxed. You can customize to have them maxed. All event Pokémon moves can be replaced with any moves that you want, as long as the moves are technically learnable by that Pokémon in the game version you will be receiving it.
• Ability: This aspect of the event Pokémon cannot be altered.
• Held item: Can be replaced with any Held Item you fancy.
• Ball: You cannot change the ball in which the event Pokémon is contained.
• Ribbon: You can add Ribbons (as long as available to the game version) to the event Pokémon but not remove the Ribbon that came with it.
• Date Received: You can customize this data if this matters to you, however, we recommend to choose a date that's within the duration of the distribution of the event Pokémon. We highly recommend the first date of release, so you get that feeling, albeit false, that you had it on the first day of distribution.
• Nickname: It is okay to give a Nickname to event Pokémon.
• Gender: Only when the event Pokémon was released with the option to choose Male or Female can you choose the Gender. If the event Pokémon was distributed as Male you cannot alter its gender to Female.
• Language: Common notion is that whenever an event Pokémon is released in Japan, its language should be Japanese (shown as JPN). However, this is not correct. Event Pokémon can come in any language, as originally they will be set to the same language as the game that received it (remember when you first open the game, it asked for the language that you prefer). So any Language is actually okay!
• All other important values such as OT name, ID number (only when it states "Yours" can it be customized to any OT and ID Number), Met Location and Fateful Encounter cannot be altered.
