* Cheats: Using cheat codes to obtain Legendary Pokémon in Pokémon Diamond is generally considered not legitimate by the community. This is because it breaks the intended gameplay experience and can be considered unfair to others.
* Events: Legendary Pokémon distributed through official events (like those hosted by Nintendo or Game Freak) are generally considered legitimate. These events often have special markings on the Pokémon to denote their event origin.
* Giratina, Heatran, Dialga, Azelf, Uxie, Cresselia, Mespirit: These are all Legendary Pokémon that can be found in the game naturally, but they are extremely rare. If you obtain them from official events or trading, they are considered legitimate. However, if you obtain them using cheats or hacks, they are considered illegitimate.
Important Considerations:
* Trading: If you trade for a Legendary Pokémon, it's essential to understand how the other person obtained it. Trading a Pokémon obtained through illegitimate means could result in you receiving a "hacked" Pokémon.
* Online Play: Using a hacked Pokémon in online play can get you banned.
* Personal Preference: Ultimately, the decision of whether or not to consider a Pokémon legitimate is up to you. Some players may be more lenient than others.
Remember: If you're unsure about the legitimacy of a Pokémon, it's always best to err on the side of caution.
