Dorian's Man-Bat Serum - The Batman Adventures

Modified by Emile Dorian from his former colleague’s research, this version of the Man-Bat formula stripped its victim of free will, turning them into a mindless pawn. 

Dorian used it on Langstrom as part of his revenge scheme against Batman and Catwoman, turning Man-Bat into his puppet. 

Dr Dorian's Island - The Batman Adventures

Following Dr Emile Dorian’s arrest by Batman and the GCPD, his private island remained under police surveillance.

Many officers grew uneasy, believing the supposedly abandoned island was still inhabited by someone—or something—unknown.

They were right. The island was still home to Dorian’s genetic creation, Tygrus.

Meanwhile, Anthony Romulus, seeking a cure for his lycanthropy, broke through the GCPD barricades and entered the island in search of Dorian, unaware that he had been imprisoned. Encountering Tygrus, Romulus persuaded him to help find his “father” in exchange for information about Selina Kyle—Catwoman—Tygrus’s unrequited love.

Dr Emile Dorian - The Batman Adventures

After an encounter with Batman, Dr Emile Dorian was arrested and sent to Arkham Asylum for the Criminally Insane. A freak lightning storm later destroyed the wall of his cell, allowing him to escape.

Fueled by revenge against Batman and Catwoman, Dorian targeted his former colleague, Dr Kirk Langstrom, forcibly injecting him with a modified Man-Bat serum.

He then kidnapped Batman and Selina Kyle, intending to perform invasive genetic experiments on them. When Tygrus arrived unexpectedly, Dorian altered his plan—promising his “son” a human body by transferring his mind into Batman’s.

Before the procedure could be completed, Dorian’s lab was attacked by the werewolf Anthony Romulus. As Dorian ordered Man-Bat to defend him, chaos erupted, and a massive fire consumed the facility. Dorian, Tygrus, Langstrom, and Romulus were all reported missing and presumed dead.

The Werewolf - The Batman Adventures

Unable to control the transformations caused by Professor Milo’s serum, Anthony Romulus sought help from Dr Emile Dorian, unaware that Dorian had been arrested after an encounter with Batman.

Teaming up with Tygrus, whom he met on Dorian’s former island, Romulus searched for the doctor before his next transformation. However, the two were separated when Tygrus witnessed Man-Bat abducting Selina Kyle from her apartment.

By the time Romulus reached Dorian’s lab, he had fully transformed into his werewolf form. Attacking the scientist, he clashed with both Man-Bat and Tygrus, and their violent struggle sparked a fire that consumed the entire building. All four were presumed dead.
