Little is known about Mr Abbott, not even his first name. He is a servant of Ra's al Ghul and, like Whisper A'daire, he is addicted to a drug that slows down the aging process. He may be around 60, while Whisper is closer to 90. They usually team up in their missions. Whisper is typically the brain of the operation, while Abbott, a cold blooded murderer, is the muscle. In fact, Whisper is as deadly or even more deadly than Abbott, but she prefers manipulation and seduction if possible. Like Whisper, Abbott has been mutated by exposition to the drug. In his case, he has become a werewolf. Abbott is equally scared of Whisper and Ra's, even though he is sexually involved with the woman. Once, when he failed in a mission, she spit poison in his face and left him scarred and blind of one eye. They both must drink the drug often to avoid aging fast.
