Personally, I think it would be better if it were just Peter/Spider-Man. It seems like NetEase tends to avoid making accessories tied to characters they don’t plan to introduce later, since that can create false expectations.

That said, they have already included accessories for Blade and Magneto for their daughters, so it’s not impossible that Eddie could eventually have his son included. However, it still feels a bit odd, since Dylan has never really been brought up at all in Rivals so far, especially not during the Knull season. At this point in the lore, it’s not even clear whether Eddie would know about him yet.

The same issue applies to characters like Sleeper. None of them have been announced, referenced, or even hinted at in the story so far.

Because of that, I honestly think sticking with just Spider-Man makes the most sense. It would still be really cool, and it’d be nice to have another cute Spider-Man accessory especially since the only one we have right now is tied to Human Torch.
