What is black flash dc?

Black Flash is a character in DC Comics who is primarily depicted as a grim reaper-like figure that represents death for speedsters, specifically those who are connected to the Speed Force. Black Flash's main role is to capture and kill speedsters when their time has come, similar to the concept of the Grim Reaper in folklore.

Black Flash first appeared in "The Flash" #138 in 1998 and has since made multiple appearances in various DC Comics titles. The character is often portrayed as a menacing and unstoppable force that speedsters must avoid or confront at their own peril.

It is important to note that Black Flash is not a traditional villain with a specific agenda or goals other than fulfilling its role as an agent of death for speedsters. The character's appearance and abilities have evolved over time, but its core purpose remains constant in the DC Comics universe.
