Hello, So I want to IV breed my Pokemon. I want a Gallade with 31 Attack and Speed IVs. I also have the according Pokemons. So, can I IV Breed those with the Power Items? Thank you.
From Pokémon Platinum onward, the baby will inherit three IVs, each from a different stat and from a random parent.
From HeartGold and SoulSilver onward, if either parent holds an Power item, the baby will instead receive the IV of the corresponding stat from that parent, then inherit two other random IVs each from a random parent; if both parents hold a Power item, the baby will inherit the corresponding stat to their held item from one of those parents at random. For example, if a parent is holding the Power Anklet, the baby will inherit the Speed IV from that parent, and it will also inherit two other different IVs from its parents, such as Attack and Special Defense. As another example, if one parent holds a Power Anklet and the other parent holds a Power Weight, the baby will inherit either the Speed IV from the first parent or the HP IV from the second parent, and it will also inherit two different IVs from its parents other than Speed or HP (whichever was successfully inherited will be the one not chosen).

As HeartGold and SoulSilver were released after Platinum, you can see that you cannot use Power items to pass down IVs in Platinum. They are inherited randomly instead.
Hope I helped!
Actually yea. You could probably do anything in Generation 4. Whether its heartgold and soulsilver or ruby sapphire and emerald plugging in. You could do something like anything which is why generation 4 is the best of all the generations.
