it could be the PDL is dying due to age and past battle that have weared him off his powers and vitality.. probably thats why he was doing remote control of his armor.

i think PDL was using a transformation spell just like Momon during his fight with the eight greed kings and six gods. it would be weak for him to fight in remote control
