* MechanicallyUnusualClass: Humans don't have claws, fur, and other things that other builds spec into. That said, they're a class that's heavily based around the Tool Use skill, and they make up for any shortcomings with inventions created because of their maxed Intelligence.
** For the majority of players, Outside is an action RPG with the ultimate goal being to successfully reproduct. For eusocial bees, ants, and wasps, however, the special ability Arrhenotoky, who allows the queen to produce male drones with parthenogenesis, transforms that ultimate goal into "collaborate with the colony to help the queen produce eggs", as the worker sisters share 75% of their DNA with one another, while they would only share 50% if their DNA with their descendance. The game is thus transformed into a RTS.

** Walruses are exemplary examples of this, being sluggish, but so durable they can tank Polar Bears, and their tusks can ward off the same. They're less sluggish in water, but that still doesn't help them in matchups against the [[invoked]]GameBreaker Orcas.
** ''Tyrannosaurus rex'' was considered this. It was noted to be not particularly fast outside short bursts of speed. If it was re-introduced in the current-day meta, it would have extremely high attack damage, but its large size made it slower than several modern-day animals. As such, [[CripplingOverspecialization the only animals it could reliably kill would be elephants]].
** Most snails are placed in F-Tier thanks to only having good defence (for their size), the worst speed in the meta, and nothing else. The Cone Snail however has an extremely high attack stat to go with it thanks to a ''very lethal'' venom harpoon that can even pierce human protection, and is a solid A-Tier because of it.

* RPGMechanicsVerse: Applies this to RealLife.

** Myriapods, like scorpions, were considered effective builds in the past due to the then-unique niche of air breathing and their fast speed in the Silurian period. However, as they've mostly stayed the same throughout the millennia, the ever-changing meta has ''not'' been kind to either. Both of them lack good eyesight unlike most arthropods, and their long bodies allow several builds with disjointed hitboxes to easily catch and kill them. Centipedes have it very rough, with their slow attack windup allowing prey to easily see them coming and escape. It's for these reasons that centipedes are considered at F-tier, even lower than scorpions, and millipedes are considered D-tier.

* CleverCrows: Corvids were considered S-tier animals in the city meta and out of all birds in general, thanks to having the high intelligence to get various loots and interactions while also sporting high mobility.

** Between the two S-ranked avian intelligence builds, Crows are considered these compared to Parrots. They lack the parrot's syrinx shriek, deal lower damage with their beaks, and are less dexterous with their beaks compared to parrots. However, Crows have the ability to use the city's terrain and features to their own advantage, and most importantly manipulate or goad other players to their advantage, sometimes even gaining them as an ally to use their strengths to cover for the crows' own shortcomings.

** Orangutans are this in comparison to the other apes. They're fast, but not as fast as chimpanzees. They're strong, but not as strong as gorillas. And they're highly intelligent, but nowhere near as intelligent as humans. According to [=TierZoo=], [[SkillGateCharacter this makes them a great beginner class.]]

** Besides the domestic dog, the other S-tier in the Dog Tier List was the African Painted Hound, not the Wolf which was considered an A-Rank SkillGateCharacter. Like the Secretary Bird, it was capable of surviving the African Savannah thanks to higher stealth, attack and speed than wolves, while also having a better hunting strategy based around [[LeakedExperience propping the weaker members]] than giving the best loot to the best members.

--->Orcas will divert the course of ships, humans will acidify the ocean, you know, classic pranks.
