1) No, since Defog is not an egg move of SkarmoryOkiee so I have a few questions..
1.) If I were to get defog on a skarm in gen 4, then move it to gen 6, can I breed it onto skarmory?
2.) Similar question to the previous question. If I have a tutor move eeveelution with heal bell will it pass on to babies?
3.) If I have knock off on tangrowth, can it be bred onto a gen 6 tang?
4.) Anyone have a garchompnite they can hook me up with? :3 I looked wherr mines suposed to be and cant find it. I can give a power item or two for it. Ooor a 5iv poke :)
Thanks for answering :D
2) No, for the same reason (but for Eevee)
3) Yes, if the thing is in Tangrowth's egg group, and has Knock Off listed as an egg move
4) Don't have one :P
For most egg move questions, serebii's pokedex is probably the best bet. Anything listed as an egg move will pass on. http://www.serebii.net/pokedex-xy/
