Grimm-Nevermore

The Nevermore is an avian that has features resembling those of several other bird species. Two notable examples of this are its resemblances to condors and ravens. Like other Grimm, it has a mask-like, white bony structure overlaying the upper front of its head. It also has four glowing red eyes, two on each side of its head. The headpiece also includes a dorsal spine or fin, reminiscent of that on the heads of condors and some prehistoric pterosaurs.

Interestingly, the Nevermore is seen to have two clawed "fingers" extending forwards from the outermost wing joint. This is a feature present in only a handful of birds on Earth, of which none are corvids. It is most closely matched by pseudo-fingers seen on the outer wing joints of ancient proto-birds like Archaeopteryx. The Nevermore is generally reminiscent of the Archaeopteryx in many ways, although it is many times larger, even in its smallest seen form.

Most likely due to the fact that they inhabit the cold tundras of Solitas, the black skin and feathers of the northern variant of the Nevermore appears to be somewhat frozen and has white patches. This variant is called the Ice Nevermore.

Whilst fully grown Nevermores are referred to as Giant Nevermores, their younger counterparts are called Nevermore Chicks.

The Nevermore seems to have the ability to easily swoop down for an attack, where it gains momentum in going straight back up. It's shown to have a tremendous amount of strength as seen when it was able to destroy a large stone structure with just one hit, as well as ramming itself into a stone bridge with little consequence. They are also known for being extremely durable for an avian variant of Grimm, able to seemingly brush off small arms fire and take even artillery barrages without dying.

The Nevermore seems to primarily resort to swooping mid-flight towards its target and leading in with its beak, then returning to flight using the downward momentum it gained during the attack. Nevermore also bear talons which they tend not to resort to, most likely relying on their momentum to keep mobile during combat.
