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.
- This version of Blackie (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
