I don't mean to point out the obvious~ but those fight were really short, and Natsu didn't even finish them off. And let's not forget who took on Tartarus all by herself, including Jackal. ^^ Natsu may have encountered all of the Demons, but others took care of them. Mira took care of Sayla, Gajeel took care of Torafusa, Gray (Laxus) took care of Tempesta, Silver was defeated by Gray, Jackal was a combo defeat and later taken out by Lucy, Keith was taken out by Juvia, Ezel by Wendy and Kyouka is fighting Erza. So really, anyone's Natsu fought to the end was Franmalth. So basically, Natsu has had some sort of encounter with 3 of the present enemies. So him fighting Mard is not all that. >___>
