Bad Egg: Difference between revisions

Bad Eggs are not really [[Pokémon egg]]s, and may possibly never have been, but instead the default message returned by the game if the checksum is off (which happens only if data is altered badly). Bad Eggs rarely hatch and cannot be released, merely taking up space, though there are methods of removing them—it is possible to [[trade]] a Bad Egg away into another game, or remove it by [[cheating]].

==Game data==

In addition to forcing an ordinary Pokémon to have an invalid checksum, it is possible to encounter a Bad Egg in the wild by using an [[Action Replay]] on {{game2|Diamond|Pearl|Platinum}} and setting the wild Pokémon modifier code to 495 (an identifier of Manaphy Egg, although a Manaphy Egg is rendered as a Bad Egg in battle). The game will freeze instantly on capture when the game attempts to show the Pokédex entry. A normal egg captured this way (using an identifier of 494) will hatch into a random Pokémon, including Pokémon that do not normally hatch from eggs like [[legendary Pokémon]] and evolved Pokémon, or may hatch into [[-----]] or, like its [[Glitch Egg|Generation II counterpart]], another egg (which will then go on to hatch into a ----- itself). Due to being incorrectly generated, whatever is hatched may eventually turn into a Bad Egg itself, and then subsequently hatch yet again. The use of an Action Replay with a "1 hit kill" cheat in double battles will often result in a Bad Egg appearing. If the player sees a Bad Egg, the game will occasionally freeze. If {{m|Transform}} is used against a Bad Egg, its backsprite will be exactly the same as its front sprite.  Also, if {{m|Transform}} is used, the only move it knows is {{m|Splash}}.

If the cheat to catch other Trainers' Pokémon is used, often the Pokémon caught, if following moving after another Pokémon, will either be named the same as the previous Pokémon or Bad Egg. There are no other side effects.

In [[Pokémon Battle Revolution]], some Pokémon that are hacked may become Bad Eggs when they are copied from {{5v2|Diamond|Pearl|Platinum|HeartGold|SoulSilver}}. A common example of a Bad Egg replacing a Pokémon is when that Pokémon has more than 510 [[effort values]]. Bad Eggs are unable to battle in Pokémon Battle Revolution.

If the player has a hacked Pokémon, although it won't appear to be a Bad Egg on a DS game, it will show up as a Bad Egg on Pokémon Battle Revolution if used in a DS battle.

In [[Generation V]], if a wild Pokémon modifier code is used to encouter a Pokémon with a [[National Pokédex]] number greater than 649, a Bad Egg may appear as a result. The Egg will flee from battle. Catching the Egg will result in the message for a successfully caught Pokémon, but the data of the Egg will be deleted after the battle. The Egg does not have a [[Pokédex]] entry or any status information. The player's Pokémon will not earn any experience after the battle. Due to the removal of [[seal]]s as a game mechanic, Generation V Bad Eggs cannot have seals.
