Pokemon Facts #46 - Paras

Early English promotional material for Pokémon Red and Blue listed Paras's name as Parasyte.
In Generation I, Poison attacks are super effective against Bug, making Paras and Parasect the only Pokémon to have ever had three 4× weaknesses.
No other Pokémon has the same Egg Group combination as Paras and its evolution.
Paras and Parasect share their species name with Shroomish, Breloom, Foongus, and Amoonguss. They are all known as the Mushroom Pokémon.
Paras can be seen as a counterpart to Morelull. Both share the Grass type and the same base stat totals, both can learn Spore, and both can be found in the wild in Pokémon Sun and Moon, taking the place of the other depending on the time, with Paras being found during the day and Morelull at night.
In the 1.0 release of the English versions of Pokémon Ruby and Sapphire, the Pokédex entry of Paras refers to it as BUG POKéMON. In the 1.1 release, this was modified to mention BUG/GRASS POKéMON instead. The Pokédex entry in Pokémon Omega Ruby and Alpha Sapphire says Bug Pokémon like Pokémon Ruby and Sapphire version 1.0, however.
