Buffy The Vampire Slayer: 10 Worst Characters Who Appeared After Season One

Season 4 was a watershed moment. The Scooby Gang packed their bags and headed off to college. Many new characters were introduced, including Professor Walsh, Buffy's psychology teacher.

At first, Professor Walsh appears to be your typical self-satisfied tutor with a sanctimonious temperament. But in reality, she's in charge of the Initiative, a demon-research facility hidden beneath UC Sunnydale.

There's nothing wrong with this setup –   it's a pretty interesting start for Professor Walsh. Unfortunately, all this intrigue comes crashing down at the end of 'The I in Team' when Adam murders the professor by stabbing her through the chest. Adam then becomes the new Big Bad, and he's lacklustre by comparison.

Whilst there are a decent number of characters who are worse than Professor Walsh, she's definitely one of the most disappointing. All that great potential is lost in just a few seconds.
