I finally started breeding myself Charmanders today, dreading it due to the the lopsided Male/Female ratio. I needed one with Timid and the other with Jolly, so I could breed whatever nature I wanted at will, since I was supposed to get a Jolly male, I needed a Timid Female with hopefully 3 or more decent IV's. I started with a Safari female with the following IV spreads....
Female - 31/xx/xx/xx/xx/31
Male - xx/31/31/xx/31/31.
I bred a full box +5 worth of eggs, hatching four females (not bad). All the males were useless to me from there nature, and only had two with 4 IV's... Three of the females inherited a whopping ONE perfect IV, either Speed or HP...
The last female? 31/31/31/xx/31/31.... I don't even want to know the odds of getting this spread from those parents and with that 12.5% gender ratio. In another 15 minutes I bred it with my Jolly Garchomp and got a Jolly male with that same spread, with all the egg moves I wanted (Dragon Rush/Pulse/Dance and Outrage).
Considering the hell it went through to breed my Salamence, totally made my day.
