Bad Egg Pokemon – mysterious phenomenon in Pokémon world

The Bad Egg (also known as “ダメタマゴ” in Japanese) is one of the most intriguing and problematic phenomena in the Pokémon gaming world. It’s not a standard gameplay element, but a security mechanism that occurs when Pokémon data is corrupted or incorrectly modified. This phenomenon has fascinated the gaming community for years, becoming both a subject of study and a source of numerous myths and misunderstandings.

What is a Bad Egg?

A Bad Egg is an error handling mechanism introduced in the third generation. It occurs when invalid Pokémon data is detected, most often due to a checksum mismatch. When the system detects that Pokémon data has been corrupted or incorrectly modified, it automatically marks it as a Bad Egg.

It resembles a regular Pokémon Egg in appearance, but its behavior is completely different. Unlike normal Eggs, which hatch into Pokémon after a set period of time, they typically cannot hatch and constitute a permanent burden on the player’s inventory, taking up space in the party or on the PC.

History in Subsequent Generations

Generation III – The Origin of the Problem

The Bad Egg first appeared in Ruby, Sapphire, and Emerald. In this generation, the bug was designated as “Bad Egg” and was the first protection mechanism against file modifications. Interestingly, only in Ruby and Sapphire could it theoretically hatch, although attempting to do so resulted in the game freezing on a black screen. In the second generation, a different bug with a glitched Egg occurs.

Generation IV and Later

In the fourth generation and later, the Bad Egg was refined as a protection mechanism. In Diamond, Pearl, Platinum, and subsequent installments, it cannot hatch and is even more difficult to remove. The system was designed to more effectively detect invalid information and protect the game’s integrity.

In recent generations, including the Nintendo Switch, this mechanism still exists, though it has been significantly improved to prevent various forms of data manipulation.

Causes of Bad Egg Pokémon

It can occur for several reasons, the most common of which are:

• Use of cheat codes – Incorrectly programmed or incorrectly entered cheat codes by the user into devices such as GameShark or Action Replay can cause corruption.
• Use of glitches – Certain glitches, such as the Battle Tower glitch in Ruby/Sapphire or the Pomeg glitch in Emerald, can lead to this glitch.
• Transfer errors – Problems while exchanging Pokémon between players, especially in older generations, could lead to data corruption.
• Hardware failures – Cartridge damage, problems with the console’s memory, or a sudden power outage during a save can all cause this glitch.
• File Modifications – Direct manipulation of files using record editors may lead to checksum inconsistencies and errors.

In-Game Behavior

It exhibits a number of distinctive behaviors that distinguish it from normal Pokémon Eggs:

• Cannot be released – Attempting to release it results in the message “You cannot release the egg.”
• Cannot be traded – In most cases, it cannot be traded with other players.
• Cannot be left at Daycare/Nursery – It cannot be left in the care of breeding centers.
• Cannot be hatched (except Ruby/Sapphire) – Unlike normal Eggs, it will not hatch after a certain number of steps.
• Can cause game crashes – In some cases, attempting to view statistics can lead to a crash.

Myths and Facts about the Bad Egg

Many myths have arisen around the Bad Egg, which are repeated in the online gaming community. It’s worth separating fact from fiction:

Myth: It infects other Pokémon

Fact: It does not infect other Pokémon in your party or on the PC. This is a common myth, but in reality, it has no ability to “infect” others. Each case is an individual result of data corruption.

Myth: A Bad Egg always corrupts a save file.

Fact: Simply possessing one rarely corrupts the entire save file. It usually simply takes up a slot in a team or PC. Problems can arise with tampering attempts, but its mere existence usually doesn’t corrupt the entire save file.

Myth: It’s a computer virus.

Fact: It’s not a virus in the traditional sense. It’s a security mechanism designed by the developers to protect data integrity. It doesn’t contain malicious code that could damage consoles or other games.

Myth: It can hatch into a Legendary Pokémon.

Fact: In standard gameplay, it won’t hatch into any Pokémon, let alone a Legendary Pokémon. In Ruby and Sapphire, attempting to hatch it results in a freeze, and in later generations, it can’t hatch at all. Therefore, it has no value in this regard.

How to fix the Bad Egg error?

Removal can be difficult, but there are several methods that can help:

• Methods for GBA (Generation III)
• Reverse Cloning – In Emerald, you can exploit the reverse cloning glitch in the Battle Tower to remove it.
• Special Codes – There are special codes for Action Replay devices that can remove it from specific slots on PCs.
• Using a Ruby & Sapphire Box – In some cases, transferring it to a Pokémon Box can help with removal.

Methods for Newer Generations

Save Editors – Professional save editing tools can help with removal, but require specialized knowledge.

Pokémon HOME – In some cases, newer games may block transferring it to Pokémon HOME, which can help isolate the problem.

Bad Egg in the Context of the Pokédex

An interesting aspect is its relationship with the Pokédex. Because a Bad Egg is not a real Pokémon species, it is not registered in the Pokédex. However, in some cases, when it is created from an existing Pokémon, that Pokémon’s data may still be visible in the Pokédex even if the Pokémon itself has been transformed into a Bad Egg.

In the third generation, it is treated as entry number 412, which can lead to interesting interactions with the Pokédex system, especially when exploiting glitches.

The Glitch Research Community

This phenomenon has attracted the attention of many researchers and enthusiasts who have devoted time to understanding its mechanisms. The online community has created numerous articles, guides, and videos documenting various aspects of this bug.

Some fans deliberately create it under controlled conditions to better understand the game’s mechanics and potential security vulnerabilities. Thanks to this research, knowledge about these bugs and how to mitigate them has become more accessible to regular players.

Bad Egg in Pokémon HOME

The latest Pokémon storage tool, Pokémon HOME, also has mechanisms for detecting and handling the bug. In HOME, a Bad Egg cannot be released, traded, or transferred to other versions. Attempting to release it displays the message “You cannot release the egg!”, while attempting to transfer it to the game results in the message “You cannot take this egg from Pokémon HOME!”.

In version 2.0.0 of HOME, a bug caused error code 10015 to be displayed if the player attempted to save changes after accessing the HOME Box menu while a Pokémon was in any slot.

Summary

Bad Egg Pokémon are a fascinating element of the Pokémon universe that combines technical aspects with the player experience. While encountering one is an unwelcome experience for most players, for fans and enthusiasts, it’s an interesting subject of study.

Understanding the mechanics not only helps you deal with this issue but also provides a deeper understanding of the technical aspects. Whether you’re a casual player or a dedicated glitch researcher, knowledge of this issue is a valuable part of your overall knowledge of the universe.

Remember, the best way to avoid this issue is to play as intended, avoid unofficial cheats, and be careful when trading Pokémon online. However, if you encounter this phenomenon, we hope the information in this article will help you understand what you’re dealing with and how to deal with it.
