>>49418752The design process probably went like this
>We need to make Dialga and Palkia look more like Arceus>Ok so let's make Palkia quadrupedal and make both it and Dialga have longer legs and necks, just like Arceus>But fully quadrupedal long-necked Palkia looks too different from the base form, so let's put its breastplate and Pearls on its neck, to simulate its former torso>Great! But Dialga still looks too similar to the base form, it barely changed compared to Palkia>I know! We'll do the same we did with Palkia and move its breastplate and chest Diamond up its neck>Perfect, now they both look more like Arceus and have a weird thing in their necks
