First time poster here, I'd personally love to see Porky in the game. I love the Mother series and I feel he'd bring a lot of interesting mechanics to the Ultimate.
Regarding the whole Absolutely Safe Capsule spirit thing, I don't think it's supposed to represent Porky. A lot of people say that the sprite used to represent the ASC is the one for when the Capsule is empty, but that's not exactly true. There are two Capsule sprites in Mother 3, but they aren't for when the Capsule is empty or full, but instead for when the Capsule is moving or still, as shown here. So if the sprite is all we had to determine whether or not Porky is in the Capsule, we wouldn't know for sure. The reason I think Porky isn't represented by the spirit is because of the summoning instructions for it. It takes a Mr. Saturn and a few shield cores to summon the Absolutely Safe Capsule spirit; the shield cores referencing the indestructibility of the Capsule and the Mr. Saturn referencing the fact that Dr. Andonuts and the Mr. Saturns are the ones who created the Capsule. There is nothing that references Porky or pigs involved in the summoning process. If the reason Porky isn't in the game is because the Smash team wanted to make a joke about him being stuck in the Absolutely Safe Capsule, wouldn't they illustrate this joke by making something related to Porky involved in summoning the ASC spirit?
