If any said Titan shifter had been eaten at the spinal cord, assuming that would be enough to consume the Titan Shifters ability, I'm certain that the Titan shifter, parted from his powers, have no means of regeneration, and I have never taken this aspect into consideration, but if a Titan Shifter had half his body torn off, and still alive, I would be surprised. After all, in almost every Titan case, they have regenerated. But, in those cases it was limbs, and heads chopped off, there has never mean a reported incident involving half a body, if there was ever a blade large enough to cut half the Titan, I'm certain they would have no means of survival.
