Here's why:
* Glitch Pokémon are unintentional: They arise from errors in the game code, not from deliberate design choices.
* Legendary Pokémon are intentional: They are powerful and rare creatures designed by the developers to be special.
* Glitch Pokémon lack official recognition: They are not part of the official Pokémon lore or the Pokédex.
* Glitch Pokémon are often unstable: They may have unusual stats, abilities, or moves that break the game's balance.
While some glitch Pokémon might share some characteristics with legendary Pokémon, like being powerful or rare, they are fundamentally different due to their unintentional nature and lack of official recognition.
