Jack file.

Sensei Jack is one of the main characters from Powerpuff Girls Doujinshi. He is the martial arts instructor, and a gym, history and hieroglyphics teacher of the Megaville Elementary. He is originated from the Cartoon Network series Samurai Jack.


He first appeared when he interupted the fight between the Powerpuff Girls and Dexter. He was first meant to punish them, but since the girls were new he let it pass, gave Dexter the responsability for being their official guide and later introduced Courage to the girls especially Bubbles. Dexter then told them about Jack being a well respected teacher and for him being a samurai. When the girls and Dexter were fighting the Dread Dragon Jack saved them. He soon appeared being surrounded by Buttercup's/ his fan club and was talking to Buttercup. He didn't appear for awhile until Buttercup went to his School Dojo to practice Kendo under him. But because Buttercup was very agressive Jack asked Professor Utonium to come to him to talk about Buttercup. The professor and Jack decided that Courage had to stay with Buttercup and take notes of what she is doing. Later he had to sell snacks along with Buttercup and Courage at the science fair, but when the Cluster invaded the science fair Jack helped to evacuate the people. He fought along with Buttercup against the Clusters. He then fight with Samantha, but wasn't fighting with all his strength for Samantha being a child. He was soon electrocuted and had his katana stolen, while he was unconscious both from Samantha. When Samantha fled Buttercup chased her to get the katana back, while Mrs. Honeydew and Bubbles help carry Jack to safety.
