As we know the spider is currently missing its 6th, 9th and 12th legs: Shalnark, Pakunado and Kortopi. Since the Phantom Troupe are currently on the ship to the Dark continent and we can only assume they want replacements I believe there will be someone or maybe even a few people from the ship that could fill the role. My prediction is Prince Tserriednich. He is training in nen and seems to be going really well with it even getting his own nen technique (assuming it isn't his nen beast) so I think by the time they arrive he will be strong enough to join. He just seems like the kind of person who would fit in with the spider but not too much which will make an interesting dynamic. I imagine him and Phinks would argue a lot haha What do you guys think? Got any reasons to think it won't happen. Got any other ideas of who could join the Spider?
