Hello, I'm an expert in the field of Pokémon lore and game mechanics. Let's dive into the question about whether a Ditto is considered a legendary Pokémon.

English Answer:
No, a Ditto is not considered a legendary Pokémon. Legendary Pokémon are typically characterized by their rarity, unique abilities, and the lore surrounding them, often being powerful or mystical creatures with significant roles in the Pokémon world. Ditto, on the other hand, is a unique Normal-type Pokémon known for its ability to transform into any other Pokémon it encounters. While Ditto is indeed rare and has a special ability, it does not fit the traditional criteria for being a legendary Pokémon.

Chinese Translation:
不，百变怪（Ditto）并不被归类为传说（legendary）宝可梦。传说宝可梦通常以其稀有性、独特的能力以及围绕它们的传说为特征，通常是在宝可梦世界中强大或神秘的生物，扮演着重要的角色。另一方面，百变怪是一种独特的普通属性宝可梦，以其能够变身为它遇到的任何其他宝可梦而闻名。虽然百变怪确实稀有并且拥有特殊能力，但它并不符合作为传说宝可梦的传统标准。
