Blackie is a hawk with black plumage. During World War II, he came to the aid of the Blackhawk Squadron who had fallen into a trap laid by Killer Shark. Blackie helped the Blackhawks escape and as such became the squad's official team mascot. Blackie shared in many of the Blackhawk's adventures during and after the war.
