Big Primids (ビッグプリム, Big Prim in Japan) are some of the more powerful enemies in The Subspace Emissary. Although they are identical to normal Primids in function, they are much larger and far stronger. They were made big as a result of having the Super Mushroom in their DNA. Its Smash Attack is very powerful, and deals a large amount of Knockback.
The biggest Primid of all. Its attacks are the same in form and function, but considerably more powerful than a normal Primid's. Watch out for its smash attack--it will launch you far. It also has jump and roll attacks. The bigger size means an increase in Shadow Bugs--does that mean it takes more Shadow Bugs to move bigger Primids?
