I have a question regarding how the Time Machine method works. Let's say I have 2 adamant flawless parents that give me a flawless egg. If I save before getting said egg, then reset my 3DS, switch the flawless parents with random ones of a different species and nature (jolly mother holding an Everstone), will the first egg from the new parents have a jolly nature but retain the flawless IVs from the egg produced back when the flawless parents were in the nursery?
No. The
inheritance is determined at this point (assuming you switch in like-for-like parents in terms of Mono-Gendered [only one possible gender, whether that be female, male or genderless] vs. Bi-Gendered). By which I mean; you would end up with something akin to: M/4/M/F/M/F on the offspring (where M denotes that the IV was inherited from the
Male parent; and F denotes that the IV was inherited from the
Female parent, and
x [where
x is a number] denotes the randomly generated IV). But when you swap in the "random" parents,
their IVs will be inherited (in the same manner).
As a concrete example; say you have:
Male: 31/9/31/31/31/31; and
Female: 31/23/31/31/31/31,
then with the above spread (M/4/M/F/M/F) you would receive a 31/4/31/31/31/31 offspring.
But if you switched in:
Male: 23/13/11/9/18/30; and
Female: 6/19/20/8/15/10,
then you would receive a 23/4/11/8/18/10 offspring...
Not a flawless one.
Additional notes:
If using Ditto + Bi-Gendered Pokémon, the inheritance
will still remain fixed. But Ditto will play the role of either F or M, depending on the gender of the non-Ditto parent.
If you test with a Mono-Gendered Pokémon, for example Kangaskhan, then Ditto will play the
other gender. But swapping to a Genderless (still Mono-Gendered) species; Ditto will
always play the role of the Female.
As an example: say you find a spread K/D/K/K/20/D (where K denotes the IV was inherited from Kangaskhan, and D denotes the IV was inherited from Ditto). This translates to an F/M/F/F/20/M spread.
Then swapping in Tauros and Ditto; the offspring would inherit the Fs from the Ditto (where previously these were inherited from Kangaskhan) and the Ms from the Tauros.
If swapping in a Beldum and Ditto; the offspring would inherit the Fs from the Ditto, and the Ms from the Beldum.
If swapping in a Bi-Gendered species; the inheritance will (most likely) change altogether.
