Males have plumage on their heads. They will never let themselves feel close to anyone other than their Trainers.
Biology
Physiology
(From Bulbapedia) Unfezant is a Pokémon resembling a gamebird. It is primarily dark gray with lighter gray markings. The light gray markings consist of a heart-shaped patch covering its face and throat, two patches divided by a lacy line on its wings, and intricate stripes with dark rimming on its tail feather. Its beak and eyes are yellow, and it has light gray legs with three clawed toes and a spur on the ankle.
The male Unfezant has a reddish pink, wattle around its eyes. Long, ribbon-like growths from the wattle extend over its head and down past its shoulders. By swinging its head, the male threatens its opponents. The male also has a mint green underside with speckling towards the chest. In contrast, the female lacks a wattle and has brown markings on its underside. It is also more adept at flying than the male.
(From Bulbapedia) Unfezant appears to be based on a gamebird, such as a green pheasant, turkey or tragopan. It is also similar in appearance to the greater roadrunner. Unfezant's gender differences reflect sexual dimorphism in real-life birds in that males have large wattles and are more colorful than the females.
Name origin
(From Bulbapedia)Unfezant may be a combination of the corruptions of unpleasant, unfazed, and pheasant.
