Human

Humans, also collectively referred to as man, mankind, or humanity, are living things on planet Earth in real life and fiction. In fiction, however, they aren't limited to just that sad little blue ball. They can live on other planets like Mars, Venus, or a totally fictional planet. They're what most stories ever told have as their Main Cast.

Abilities and the lack of them
In reality, humans are known for their continuous progress forward into a Utopian Future with research in many spheres of society such as government, politics, and technology in general. But aside from always finding a new way to amaze themselves, humans don't have many natural abilities. They can't fly without airplanes like birds, they can't swim all that powerfully like fish, they can't use magic or superpowers like mages or superheroes, and they can't do anything really cool without machines. They die to just about everything they encounter if it comes in great enough doses: fire, water, gravity, incoming objects, plants, other animals, and even air.

Humans and other races
Humans often don't get along with other races such as animals and aliens. They're also seen as inferior to other intelligent races that were able to leave their home planet, run more advanced societies, and have more abilities than humans. When intelligent alien races encounter humans, they might begin an Alien Takeover that humans could somehow overcome despite being depicted as worse than the aliens in almost every way. If humans aren't the focal species of a Humans 'n' Animals story, they'll likely be portrayed as the Nature Haters who destroy the environment so they can expand their vast empire while the animals can't do anything but helplessly watch as their homes are bulldozed by the heartless, selfish humans.
