The skeleton with a sword is an unknown character who appears briefly in the episode "Web Weirdos." Unlike most skeletons on the show, he is motionless, resting face down on the ground. He has a glowing sword clasped in his hand. Ed comes across him when he is wandering through the woods and takes the sword as a present for his wife Barb.
The skeleton wears a blue helmet with one pair of moose horns, a blue chest plate, and a dark-purple cape with a crest embroidered into it.
