8. Dr. Phosphorus

One of my favorite underrated Batman villains. But also, he is ridiculous as a concept, so I gotta put him on here. I mean, when we eventually get to Killer Moth, who is my favorite Batman villain of all time, he is most definitely going on this list.

So Dr. Phosphorus started life as Dr. Alex Sartorius. Holy hell, an ACTUAL doctor; you would be shocked at how rare that is. Dr. Sartorius was a member of Gotham City’s Tobacconists’ Club, which I guess was a club for tobacco enthusiasts? Sartorius was talked into plunging his life savings into a private nuclear power plant, which seems like a bad idea. I’m, um, I’m not sure how he expected to make money from this.

While he was inspecting his investment, the reactor suffered a rupture and blasted Sartorius full of sand from the sandbags he was hiding behind. The radiation also blasted the sand up one atomic number, turning it into phosphorus. If you know anything about chemistry, you might recognize this as not being how LITERALLY ANYTHING works, but whatever. This caused him to turn into a burning skeleton man, becoming Dr. Phosphorus.

Also, the Who’s Who lists his weakness as “oxygen deprivation”, which is also a weakness for all other humans.
