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.

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, such as 'munch' instead of 'mutual'.

Marcello hired an assassin called Bloodstorm to kill the creature and he attacked Sludge with an explosive arrow.

She was investigating the same case that interests Frank and she discovers Veffir Voon Iyax, a humanoid, albino alligator-man.

[4] Sludge also met the villain Lord Pumpkin alias The Pump who offered the creature a swift death if he obeys him.

The drugged Bloodstorm was sent to Sabatini and slaughtered the mafia, but the Dragon Fang began new attacks against Pumpkin gang, killing much of his henchmen.

Sludge has tremendous strength and durability, as well as vast regenerative capabilities, allowing him to heal from near-fatal wounds in seconds.

[8][9] In June 2005, when asked by Newsarama whether Marvel had any plans to revive the Ultraverse, Marvel editor-in-chief Joe Quesada replied that: Let's just say that I wanted to bring these characters back in a very big way, but the way that the deal was initially structured, it's next to impossible to go back and publish these books.There are rumors out there that it has to do with a certain percentage of sales that has to be doled out to the creative teams.

While this is a logistical nightmare because of the way the initial deal was structured, it's not the reason why we have chosen not to go near these characters, there is a bigger one, but I really don't feel like it's my place to make that dirty laundry public.
