I got quite a few Pokemon you may be interested in. What I'm interested in is your Sport Ball Scyther, Heavy Ball Koffing, and Safari Ball Kangaskhan. Mostly however, I'm looking at the Sports Ball Scyther and the Kangaskhan. On all of them I'll do Female for Female and if it makes it easier for you Spitback for Spitback. What I can breed is:
Larvitar | Guts
Female | Adamant | 31/31/31/xx/31/31
Dragon Dance | Outrage | Pursuit | Stealth Rock
Skarmory | Sturdy
Female | Impish | 31/31/31/xx/31/31
Stealth Rock | Brave Bird | Whirlwind | Drill Peck
Heracross | Swarm (can get guts but it may be a while)
Female | Adamant | 31/31/31/xx/31/31
Rock Blast | Focus Punch
Misdreavus | Levitate
Female | Timid | 31/xx/31/31/31/31
Nasty Plot | Ominous Wind | Destiny Bond | Spite
I am well aware that you have both a Larvitar and a Heracross. However, the Larvitar is a different nature, different Pokeball, and different Egg moves. As for the Heracross, yes they are in the same type Pokeball, but I feel like Focus Punch would be a more valuable egg move for you than Megahorn would be, since Heracross can learn Megahorn before level 50 and Focus Punch is only a Gen 5 egg move. So, I felt like it might be worth something to you. :)
