[1] Daya Vaidya portrayed a female version of the character — Peia Mannheim — in the third season of the television series Superman & Lois.

He hears Baphomet repeating the sound before turning in horror to see Onomatopoeia midway through slicing Silver's throat and mimicking the noise of the blade.
