Freex #6 Malibu Comics (1993)

Frank Hoag was an experienced but corrupt NYPD detective who finally decided to change to take action when he was asked by his mob bosses (John Paul Marcello and Vittorio Sabatini) to kill a fellow dirty cop. When he refused, his own murder is ordered; he dies by a hail of bullets as well as a bomb.

The explosion covers him with chemicals, which combine with the sewage from where the mobsters dump his body. The chemicals had regenerative properties and tried to heal Hoag, but combined the sewer substances with his body, transforming him into a huge mass of living slime.

He awakens with a raging anger against criminals and an inability to think and speak coherently, with many words coming out replaced with one that sounds only vaguely similar.
