John Smith was a villain who appeared in the Totally Spies episode "Soul Collector".

Since 1287 Common Era, he had been using the 3 Jewels of Sumatra to extract youth from others and give himself eternal youth. He was able to make the other teachers his lackeys by promising immortality and eternal youth to them in exchange for their subservience and loyalty.
His master plan was to use the jewels to extract the life force of thousands of children and teenagers who would be attending a rock concert, effectively making him eternally young. However when the girls are able to reverse the jewel's effects all the life force he has stolen is returned to the victims and he ages into dust.
- He is the only villain so far to effectively die in the series.
