Ronnie (Beneath You)

Ronnie is Nancy's abusive ex-boyfriend. He was turned into a Sluggoth Demon by Anyanka after Nancy made a wish that, one would assume, resembled her wishing Ronnie were a worm.

Xander, Willow, Buffy and Spike try to convince Anyanka to do the right thing by changing Ronnie back to human form but are initially unsuccessful, so Buffy and Spike set out to stop him from causing more harm.

Xander finally does convince Anyanka to change him back, and at that very moment Spike is lunging at Ronnie (in Sluggoth form), and impales Ronnie with a steel pole through the shoulder just as he is reverted to human form.

Xander calls for an ambulance and it's assumed Ronnie recovers from the shoulder injury.
