Eel Capone is a Mobian eel and an undersea crime boss who briefly tangled with the Forty Fathom Freedom Fighters. Capone, who proved so formidable that he drove Dr. Ivo Robotnik's sub-boss Octobot from his territory, used his "hired mussel" to subdue several of the Freedom Fighters and take over most of the area. However, he was defeated when Bottlenose, a Mobian dolphin, used his Finja skills to defeat him and send the crime lord packing. (SMM)
- Eel's name is an obvious pun on the famous mobster Al Capone.
- Eel Capone only appeared once in the series, most likely due to being confined to the ocean.
