[General Fiction] I'm a generic bad guy at Episode 50 of a series. How do I kill the Main character of a series named after him and make sure he stays dead?

1. If the series has a supernatural setting you could turn the main character into a vampire or ghost. Though they might still get their revenge, dead or not. 

2. If the series is named after the character's alter ego or superhero identity rather than their personal name, you could train a replacement. Though again you might be their first target. 

3. Failing that you could focus on making a side character vastly more popular than the main one before going in for the kill, resulting in a successful spin off and an Episode 50 finale for the original.
