into horrific monsters. Batman initially suspects Karlo, who has broken out of Arkham Asylum. Realizing Karlo needs treatment more than imprisonment, Batman asks him to join his team. Karlo agrees, and working with Batman, Nightwing, Batwoman, Orphan, and Spoiler helps to defeat Strange's monsters. At one point, Karlo used the alias of "Matt Hagen". The government agency A.R.G.U.S. creates a quarantine zone encompassing the neighborhood where the creature died, nicknaming it "Monstertown". A consultant for A.R.G.U.S., Dr. Victoria October, takes charge of "Monstertown", the area of Gotham City affected by Strange's serum. Clayface patrols the sewers beneath Monstertown, retrieving for Dr. October monsters created by leaking serum. Dr. October offers to work on a means of returning Clayface to human form permanently. She asks him to stay in his monstrous form for as long as possible so she can chart the mental degradation he undergoes the longer he remains nonhuman. She also acts as his counselor when he despairs of a cure. Dr. October calls the Clayface persona a "fear response" that occurs Karlo's mind abandons empathy and embraces anger. Batman has Clayface wear a high-technology forearm device (later replaced with a smaller wristband with a longer-lasting power source) that enables him to regain human form without using his powers—reducing the psychotic effect being Clayface has on Karlo. The device is not a cure, as the Clayface DNA consumes Basil Karlo's human DNA whenever he is locked into human form. Dr. October gives him a "placebo" bracelet with messages from his close friend Cassandra Cain (Orphan), which helps him focus on retaining his sanity. After pushing past the twelve-hour mark, Clayface loses his sanity and attacks Dr. October. Orphan intervenes, saving her life by putting the real bracelet back on. Victoria cares deeply for Karlo, and later calls him a "great friend". Dr. October expresses a desire to test her cure on a less serious case, and Karlo tells her of Glory Griffin. Karlo also tells Glory about the potential cure, although she refuses to forgive him for what he did to her. Later, with the cure close to being finished, Clayface is captured by Glory when the villain First Victim takes over Arkham Asylum and releases her. Glory removes Clayface's wrist controller, and he goes insane. As Clayface rampages through Gotham to confront Batman, Batwoman obtains a weapon which can destabilize Karlo's molecular structure, killing him. During his attack
