The protagonists are very similar because they are both the "lame" lady-killer types that are secretly really smart and at times really sensitive. Lupin and Dandy both do odd-jobs for a quick buck but Lupin is definitely more successful in his adventures. They're also kind of similar in the sense that they are total opposites - one takes place in a futuristic space setting and one takes place in a historical-looking modern Italy but both have an underlying mystery/adventure style.
