Oh, I think it could happen. The bosses could see something they like more, they'd stick P*k*m*n in a crappy time slot, play musical time slots without advertising, keep pushing the new thing while forgetting P*k*m*n exists, eventually the ratings'd get down to where theyt;d have an excuse to ax it. That's what happened to the Silver Age shows, right? Or they wouldn't even need the excuse; Road Rovers got higher ratings than Superman but goot axed anyway. If I'm wrong about any of this, tell me how they got flushed down the KWB toilet & you'll have how it could happen to P*k*m*n.
If you don't like your options, make another option.
