Eli tries a fusion shot on Dr. Blakk's unstoppable train but he uses the wrong slugs and shorts out his gang's slugs. The Shadow Clan confront Eli and teach him how the Enigmo slug has the ability to allow the Slugslinger to see a slugs aura. Eli, learning more about the double barrel-fusion shot, confronts Blakk's Gattler and destroys his new Slugterrian Express train.
