Mr. Noxious

A sinister presence lurking in the pages of DC's Detective Comics, Mr. Noxious made his debut in issue #946 (2017), conjured up by the acclaimed creative team of James Tynion IV and Eddy Barrows during one of that title's most celebrated Modern Age runs. With only a handful of appearances to his name, he's a rare and elusive figure — the kind of deep-cut villain that serious collectors love to track down. Sharing those dark Gotham pages with heavy hitters like Batwoman, Cassandra Cain, and Basil Karlo makes every one of his scarce appearances a genuine find.
