Orange Herald
The main antagonist
- Hypocrite: In the second episode, when Cracklin asks Orange Herald why he murdered all the people in the station, Orange Herald denies it, calling the accusation "vile" and asking if he looks like "a serial killer, or some kind of terminator". Then again, he's a cruel scientist who plans to murder his subjects after (or while) experimenting on them.
- Names to Run Away from Really Fast: Orange Herald is a nuclear bomb that's the largest fission device ever detonated.
- Obliviously Evil: Double Subverted, as Orange Herald is completely aware that he's killing the objects he's experimenting on but doesn't know that the objects are actually human beings.
- Token Human: Maybe, it's unclear is he is a human broadcasting to a TV or if he is the TV itself using a human avatar.
- Walking Shirtless Scene: Does not wear a shirt under his jacket.
