One of which is sonics. It's not his kryptonite, but is a thing that Superman has in his arsenal.
And will use, as I asked the OP if Superman will use his full abilities (not can he or would he, but will he).
It shows that there are things that can hurt him, but a high sonic beam didn't outright beat him. The comic implies that Juggs wouldn't have been immobilized without the "synapse dislocuter"
Which is consistent with the Ironman/weakened Juggs showing - he isn't falling, he's just in pain.
If Classic Juggs would use his full abilities, it makes it much harder for Superman. There's the kinetic shield, but also a bunch of other random powers that Cain (not other Juggernauts) has used, and passive abilities that he's shown like magical healing, iirc.
