Plasmus: the superhero lost in acid

Published on 2026-07-02 | Translated from Spanish

Otto Von Furth, better known as Plasmus, is one of those DC Comics characters that most have forgotten. Created by Marv Wolfman and illustrated by George Pérez, he debuted as a scientist who, after an accident with acid, transformed into an amorphous and corrosive mass. His story is brief and tragic, typical of the 1980s.

green toxic acid spilling from broken laboratory glassware onto a scientist in a white coat, his body dissolving into a bubbling amorphous green sludge, corrosive liquid eating through metal table and floor tiles, retro 1980s comic book style, dramatic overhead laboratory lighting, cracked safety goggles nearby, swirling acidic puddles spreading across the floor, industrial pipes and chemical tanks in background, visible reaction bubbles and vapor clouds, cinematic action scene showing the transformation moment, photorealistic technical illustration with high contrast shadows and neon green glow

Controlled decomposition as a power 🧪

Plasmus possessed the ability to dissolve organic and inorganic matter upon contact, thanks to his semi-liquid body with extreme pH levels. His physiology allowed him to shape his form to pass through tight spaces or envelop targets. However, his chemical instability required a specialized containment suit. Without it, his body slowly evaporated, limiting his appearances to short, controlled battles.

The superpower of disappearing from the comic 💧

The irony of Plasmus is that his greatest feat was disappearing from the editorial radar. With a power that basically turned him into a walking puddle, it's no wonder writers preferred less... liquid villains. In the end, Otto liquefied into oblivion, proving that not everything that glitters is gold, nor everything that melts is cheese.
