• Generation 1:
Charmander (x/31/x/x/31/x) x Ditto (31/x/x/31/x/x)
hatch a few eggs until you get male and female Charmanders with complementing IVs. Pick one of them for:
• Generation 2
Charmander (31/31/x/x/31/x) x Ditto (x/x/31/x/x/31)
breed them until you've got Charmanders with 4 IVs again, then breed those with one from the first batch, like this:
• Generation 3
Charmander (31/31/x/31/x/x) x Charmander (x/31/31/x/31/31)
breed those until you get Charmanders with 5 IVs, and then mate those to mass-produce 4–5IV Charmanders until you get the desired spread:
• Generation 4
Charmander (31/31/31/31/31/x) x Charmander (31/31/x/31/31/31)
