The event was first chronicled in Blood Syndicate #1 by Dwayne McDuffie, Ivan Velez Jr. and Denys Cowan, and Static #1 (April 1993) by Dwayne McDuffie and Robert L. Washington III.
The Big Bang is an event where gang members were sprayed with a radioactive, mutagenic gas intended to act as a tracer.
The concept was created by Christopher Priest and inspired by urban legends of a chemical-laced soda that sterilizes black people.
[1] The Big Bang appears in Static Shock.
Additionally, Ebon attempts to initiate a second Big Bang on two occasions, but is foiled by Static.
