Peia Mannheim (UE-43)

"Everyone calls it something different, experiences it in their own way, but the pull, as I call it, happens to anyone who sits in this chair. The pull? This disease, it tests every part of you, mentally, physically. And at some point, you get this feeling, this... this pull. That it'd be so much easier if you'd just let go. It doesn't mean that you don't love the people in your life or that you wanna leave 'em, but... that feeling to give into the disease gets to be so strong. So this drive that your wife has, she's gonna need to use all that energy to survive."

- Peia Mannheim and Clark Kent

Peia Mannheim is the wife of Bruno Mannheim and a patient at Hob's Bay Medical Center. Mannheim is also an assassin known as Onomatopoeia and is a member of Intergang with the ability to manipulate sound.

Duel in South Metropolis
In 2023, shortly after Atom-Man was defeated by Superman, Onomatopoeia manipulated sound and sent out energy blasts that mimicked the sound of gunshots. While there were no bullets, the mimicked sound pierced Miller's skin and shot him to death, confusing Superman. Onomatopoeia was then seen by Superman, though was able to mimic the sound of people in danger to distract him long enough for her escape. The corpse of Atom-Man was soon brought by Onomatopoeia back to the possession of Bruno Mannheim, who ordered Aleister Hook to resurrect him.
