From the novel; Julius Ceasar

'And for Mark Antony, think not of him;
For he can do no more of caesar's arm
When caesar's head is off'.
This means that Mark Antony

will be assassinated with Caesar

will become harmless once Caesar is dead

is as powerless as Caesar's arm to control Caesar

is as dangerous as Caesar's arm

cannot do more harm as Caesar is capable of.
