Undefined was sort of a Revengerist series where they came back a few years ago, although most people don't remember much about it like which ones even came back for the project and most people cannot tell you much about it. It's somewhere on the forums but someone deleted it off of youtube, no one knows why. It was more of a single one-shot project than a comic book series, but the voice acting wasn't memorable or if it was even the original ones. You know it may have been a fan thing, its hard to tell sometimes.
Those who have seen it will say it was actually their most brilliant Revengerists work and really underappreciated but to this day I can't really make out their arguments for why they think it is so damn good. I think maybe something may have happened to their brains as a result of seeing it. Like irreversible things. These were people but now they're... changed forever. It's like death, I suppose. The person they were is dead. But there's no funeral.
