A ditto, if you can get your hands on one.
Well, obviously a female and a male sceptile will breed, but besides that, any Pokemon cannot breed outside of its egg group. Serebii.net has a full list of Hoenn and Johto region egg groups. Just Google Egg Groups, and it should come up. You can find all of Sceptile's possible mates there.
In Pokemon Sapphire, the only egg you get from an NPC is the Wynaut Egg from the old lady in Lavaridge Town. You can get an egg from any Pokemon that can breed, as with any other Pokemon game that has the Day Care that allows you to leave two Pokemon there. You can breed any Pokemon that can breed with Ditto (except for another Ditto), which can be caught in Pokemon FireRed and LeafGreen and traded to Sapphire.
yes but ditto can breed with any Pokemon male or female
Yes u can breed any Pokemon with ditto but only male Nd female not the Pokemon wit no sex
