Biosite Parasitic Pokemon Type: Normal Ability: Parasite
HP: 50 Attack: 70 Defense: 50 Special Attack: 70 Special Defense: 50 Speed: 70
Sounds pretty crappy, but its performance in battle isn't what it's about. Its ability, Parasite, is the main focus of it. When you are out of battle, you can use Biosite's Parasite ability to attach it to one of your Pokemon, much like an item, but it doesn't take up your Pokemon's item slot. When Biosite is attached to a Pokemon, that Pokemon's stats (with the exception of HP) are boosted by 50%, but at the cost of losing 1/6 of their HP each turn. Also, when Biosite is attached to a Pokemon, it still takes up one spot in your party, even though it isn't an active member of the party, meaning that you cannot have a full party of 6 if Biosite is attached to a Pokemon.
R.I.P. Pokemon Cycle Fact: Things are so much better when taken at face value.
