"One Plus One Equals Two" is the eighth and final episode of the first season of the animated anthology series, The Boys Presents: Diabolical. Unlike other episodes, it was designed to be in the same continuity as the main live-action series. Its animation was inspired equally by classic American super hero animation and anime. It was released on March 4, 2022 on Amazon Prime Video.
Even a great American hero like Homelander had to start somewhere...
When Homelander first joins The Seven, he is paired up with Black Noir to handle a hostage situation at a chemical plant. Madelyn convinces Homelander that he should not let Black Noir upstage him while handling the crisis.
When Homelander gets to the chemical plant before Black Noir, he tries to peacefully resolve things himself. However, things quickly go south when he kills the terrorists and the hostages in a fit of rage. Fearing Black Noir will rat him out to Vought International, Homelander tries to kill him but accidentally blows up the entire chemical plant instead.
Instead of telling everyone what really happened, Black Noir kills any witnesses and teaches Homelander on what to say to the media.
In the aftermath, Homelander's ratings increase despite his failure to save anyone from the chemical plant disaster. As Homelander and Madelyn walk out the office, he remarks that Black Noir did teach a thing or two about being a superhero after all.
