Wait! You're talking Juggernaut as in Marvel Comics Juggernaut? Lol =) How was that again... that Juggernaut got a thousand fold powerup due to some Gem and as long as he was in the possession of that gem he could even bend space-time among billions of other things (interesting in the light of Bleach might be his ability to increase his strength, to increase the force behind his punches as well as his ability to grow in size...) O Dear... Hmmm, Juggernaut's weakness is the removal of his helmet...

I totally agree with you that the only way James can be killed is by complete bodily annihilation. That's why I think Rukia could be of interest here (unless Renji made major progress with his Kido ;) I think slicing him up would be kinda worse as he can then multiply into more (sub-) James-es. In that sense it really feels like James is just some bacterium-like thing ;)
