Humans are implied to be sexually compatible with several of, if not all, the alien species in the universe, as several hybrid human and alien citizens exist. This is portrayed best with Gwen, who is of both human and Anodite. Another notable example is Ester, who is of both human and Kraaho.
Powers and Abilities
As the attributes of humans are well-balanced mentally and physically, they are able to survive in almost every kind of environment, which negates the weaknesses of alien hybrids who are half-human. For example, Ester describes Earth's surface temperature as "nippy", whereas a pure Kraaho would be at great discomfort on the surface.
Humans are excellent climbers, being able to climb almost anything.
Humans are very adaptable both mentally and physically, been able to adapt to environment changes quickly and figure out how to deal with unexpected and stressful situations better than most species. For example, whenever Ben can easily figure out what to do and what is going on, Rook remains highly confused.
Humans are the best long distance runners on Earth, one hunting tactic employed by ancient humans was to chase their prey until it became too exhausted to continue fleeing.
Compared to many alien species, whose biology makes them naturally strong, humans have about or below average physical strength. Even if they were to train themselves to improve their physique, the untrained average human would most likely be beaten in a fight with an alien.
Any strength humans have usually comes from their numbers, making them highly vulnerable when alone.
Besides their strength, humans are not considered to be very intelligent.[DJW 1] In general, they have about or below average intelligence compared to species such as the Galvan and Cerebrocrustaceans.
- If an alien were to use the Omnitrix to transform into a human, they would most likely resemble Ben due to his connection to the device. This would give them the power to crave chili fries, even if they are disgusted by them.[DJW 2]
- Other than Max, humans are considered an insignificant race from an unfashionable western spiral arm of the galaxy.[DJW 4]
- Manny Tennyson was mentioned in Gwen 10, a non-canon episode. It is unknown if he exists in the canon timeline.
