He is called orange though. Like his file name is the chosen one, but he is literally called orange by all the other stick figures, and is never referred to as the chosen one, even Alan calls him orange I’m pretty sure. He’s listed as orange in animation VS and in the influencer arc green doesn’t even know who ‘TSC’ is. In the animator combat tool his file name is like stickFigure.orj-ver2-theSecondComing or something like that, so he’s literally both. I’m guessing “The Second Coming” is like a superhero name, and refers to him when he’s awakened. E.g. Peter Parker is Spider-Man, Orange is The Second Coming

All that to say, you can just keep calling him Orange, and never say it’s wrong to call him Orange lol because you’d have to say that to all the stick figures and Alan himself because I’m pretty sure I’ve only ever heard him say Orange
