>>8435159Truth be told, I'm not actually sure, I don't recall disassembling any figure with waist and a mid torso joint. BUT, I have taken apart the Prisoner from Fortnite, who actually doesn't have a mid torso joint and just has movement at the waist. I have that pictured here. This little tube assembly connects one ball at the base of the waist to the ball on the inside of his torso, so this may be what we can come to expect from Spawn.
On the topic, I'm pretty sure even figures with both parts cut are just connected with a longer one of these tubes, so it would effectively act as one ball at the base and one at the mid torso. I'm messing with a few figures I have a round and they don't feel like there's a second point of movement at the waist that a true double ball would allow.
