Celebi

Celebi, the Timetravel Pokémon, is a mythical Grass/Psychic type introduced in Generation II of the Pokémon franchise. Known for its ability to travel through time and heal forests, Celebi is often depicted as a benevolent guardian of nature. It has no evolutionary relatives, standing alone as a singular, powerful entity. In the games, Celebi is typically a special event Pokémon, making it a rare and sought-after addition to any player's team. Its unique typing gives it resistances against Water, Electric, Grass, Fighting, and Psychic types, but leaves it vulnerable to Fire, Flying, Poison, Bug, Ghost, and Dark attacks. Celebi plays a significant role in several Pokémon movies and anime episodes, often appearing when the balance of nature is threatened. Its association with time travel and its elusive nature have cemented its status as one of the most mysterious and beloved legendary Pokémon. Its diet primarily consists of berries and other natural flora, which it helps to cultivate, and its behavior is characterized by shyness and a tendency to appear only to those with pure hearts.
