Rarity is a count that indicates a slug species' level of rareness.

Levels of Rarity

So far, slugs are seen classified into 1 of 6 levels of rarity: "Common", "Uncommon", "Rare", "Extremely Rare", "Ultra Rare" or "One-of-a-kind".

  1. "Common": indicates that a species is commonly found and comes in large numbers.
  2. "Uncommon": indicates that a species comes in large numbers but can be tricky to spot.
  3. "Rare": indicates that a species is large in numbers but can only easily found in certain areas.
  4. "Extremely Rare": indicates that a species is few in numbers and can only be found in a certain area.
  5. "Ultra Rare": indicates that a species is very few in numbers with there almost being no chance to spot more than one of each species let alone spot even one.
  6. "One-of-a-kind": indicates exactly what it says, only one of each species exists in all of existence.

  • Oddly enough, rarity levels also refer to power levels
  • Officially Tazerlings are classified as Common slugs, but oddly enough in the episode Roboslugs, they're seen classified as Uncommon on Quintin's database.
