Where it came from
Doctor Phosphorus, or Dr. Alex Sartorius, originated in Detective Comics #469 in 1977, created by Steve Englehart and Walt Simonson. The character emerged from the darker, more atmospheric era of DC Comics, designed as a radioactive antagonist whose skin burns perpetually due to a meltdown experiment. His visual design, characterized by a translucent, glowing aesthetic and skeletal features, reflects the influence of body horror and supernatural archetypes popular in 1970s superhero storytelling.
The 71020-18 figure is part of the LEGO Collectible Minifigures series released in 2018 to accompany The LEGO Batman Movie. This rendition captures the character's signature look through specialized translucent parts and intricate printed details that represent his scorched, irradiated appearance. It was received favorably by collectors for its commitment to recreating a relatively niche comic book villain with high-quality, mold-specific elements that diverge from standard figure construction.
