When Sandman and Hydro-Man accidentally slammed together, their molecules combined to become the Mud-Thing.

Unlike the two men who formed it, Mud-Thing seemed to be a mindless brute with only vague memories of their lives before. Because of this, it sought out, without fully understanding why, Sadie Frickett, whom both the Sandman and Hydro-Man had feelings for. When it found her, she sensed a friendly aura about the monster and, rather than allow the police or Spider-Man to harm it, Sadie petitioned attorney Matt Murdock to help her gain legal custody of the beast.

The creature soon gained popularity among the public as a Broadway showpiece, with Sadie raking in the cash made by the Mud-Thing's appearance. However, when it saw her kiss the showbiz agent in an act of excitement, memories of Hydro-Man and Sandman's love for the woman sent the Mud-Thing into a blind rage, and it started destroying everything in sight. Only the sound of Sadie's voice could calm the creature out of its rampage. It grabbed her in its hand and fled with her after sensing the authority's attempts to destroy it. The Mud-Thing met its end when it climbed to the top of a New York skyscraper where police helicopters were waiting. The choppers began spraying it with a special chemical formula that dried up its body and caused it to crumble apart until it was nothing more than chunks of dirt scattered across the pavement.[1]

The remains of Mud-Thing were gathered up by the NYPD who attempted to separate Sandman and Hydro-Man using various chemical and radiation treatments. When nothing worked, the remains were tossed in a dump where the two criminals finally separated after the last radiation took effect.[2]


Mud-Thing possessed an unknown level of superhuman strength. Its sandy body gave it superhuman durability as the sand could absorb most forms of impact. Mud-Thing could also reform parts of its body if damaged. Absorbing water and sand allowed Mud-Thing to grow in size and strength.


  • Mud-Thing possessed limited intelligence and would rampage uncontrollably if angered.
  • It needed to retain moisture to hold itself together. If the moisture was removed, it would fall apart.
  • As both William Baker and Morris Bench were American citizens and single, it can be reasonably assumed that the Mud-Thing was as well, though it may not have been aware of the fact.
  • Mud-Thing's rampage and eventual end is similar to that of the famous monster King Kong.
