If the Crow is harmed or killed, the reborn becomes vulnerable.
However, the Crow also seems to be much more enduring than a regular bird and might possess some regeneration abilities (e.g.
in 'The Crow" movie the bird survives after being shot with a rifle). Although the person brought back to life by the Crow is invulnerable, he/she does have one weakness: because the magical crow is the source of their connection between life and death, if it were to be harmed or killed, this would leave the reborn vulnerable to attack.
However, even in case of the crow being harmed, the reborn loses many of their special abilities, e.g.
to see a person's memories when touching their eyes.
In addition the reborn is supposed to lose their invincibility when he or she considers their mission completed.
The Crow is the main protagonist of The Crow comic book series, originally created by American artist James O'Barr in 1989.
The protagonist is a fictional undead vigilante brought back to life by a supernatural crow to avenge his own death and that of a loved one.
The character has subsequently appeared in several feature films, a television series, and spin-off novels.In the various incarnations, films, and spin-offs, many people have taken on the Crow persona in order to avenge their own wrongful deaths.The Crow itself is a supernatural bird that serves as the protagonists' link between the living world and the realm of the dead.The magical crow is capable of resurrecting people who have been unjustly murdered and/or have left behind a terrible sadness that prevents their soul from resting, so that person may be able to seek vengeance on the person or people responsible for their death and suffering.During the person's "rebirth", the crow serves as a spiritual guide, helping the individual tap into his or her potential and assisting in tracking down the wrongdoers.To other people, the crow seems to be nothing more than a common bird; but the crow is capable of speaking to the reborn, often helping guide them to exact their revenge.
