Although Archeops are ancestral to all modern birds, one of this pokemon's most defining traits, to the gratitude of bird keepers everywhere, has not survived into modern times. When wounded, the more robust species of birds will typically perch on the ground or a tree branch to recover the damage at the cost of temporary flightlessness, while those with more fragile builds typically utilize their speed to go down fighting. Archeops, much to their trainers' chagrin, do neither.
Archeops are among the most powerful pokemon to ever fly above the world, but their power has come at the cost of their endurance. Their wings are the initial model of flight, with all the fragility and design flaws which that fact implies; they struggle to lift their own weight should any part of the body, not only the wing, be even modestly damaged. In the wild, wounded Archeops almost certainly flew away from any confrontation which left them wounded, for their ability to fight was dramatically impeded by injury. This behavior is known less from the fossil record than from the herculean efforts which modern Archeops trainers make to prevent their own pokemon from doing the exact same thing – for even a wounded Archeops can deal some damage to their opponents, even if barely half as much as before.
Of far more interest to modern bird keepers is the brilliant, rainbow-colored plumage of these pokemon. Although many modern avian species use bright colors to communicate their type or attract a mate, it has often been opined that Archeops' feathers are more beautiful than any of its descendants, and that their loss in modern birds is a great tragedy of evolution – although as birds from Pidgeot to Chatot demonstrate, the loss is not nearly as universal as this lament implies.
