OK, some of u might think the real reason why Invader Zim was canceled was because of Spongebob of possibly Bloody Gir. Wrong. The real reason is because there were wrong ratings. It was rated 9-12 years, and people who were between the ages of 14 and 18 liked it more. And also it was getting pricy to air it. I'm not saying this because I like Spongebob of Bloody Gir either. Spongebob is gay. door the way, I love Invader Zim and the reason why I'm telling u this is because: So u don't hold a grudge on something u don't need to. Please no negative commentaren towards me. Please, I love every Invader Zim fan a whole lot. :D
