-He has infinite stamina in that he can never get tired but still has an upper limit in which if cross he will overexert himself
-I assume if he were ever cut, there would be no blood
-I also assume no heart beat or pulse would be found on him
-I also assume that none of his organs work and he could survive injuries that would otherwise be fatal in a living body.

(See the villains all having a spike driven through their stomach and they survived)
-Durability likely would increase
