“He's about what I expected him to be, and I'm not sure if that's a good thing or a bad thing. Overall, I'd recommend him as a parts pack for sure. Like, way for sure. As a character, I'd probably recommend him over most of the other villains, whom I think are far more boring... More than Corroder. But as a set, I'm just not sure.”
