Welcome to the Primal Page.
When a creature is primal, it usually owns many strong physical attacks.
Primal creatures are essentially beasts that always have Berzerk active. (Metaphorically, not cosmetically.)
Primal-types are often fast and have an edge to their physical attack.
Take the Luproo for example.
Fast, destructive, and cosmically resistent.
-Here is an opinion from the person who wrote this.-"Personally, I think that Primal-types are mentally weak, which means they have a mental shield from cosmic attacks, like Flare or Starshine."
