Controlling Parallax Hal was no easy task.
Compared to Anti-Monitor, who could never truly break free of the Over-Time Stream and could only create avatars to indirectly influence its current timeline, stripping him of his free will was even more of a pipe dream.
Although Parallax Hal was currently lying on the ground, whenever Chen Tao or Barbatos raised or waved a hand, he would be blocked outside by a barrier made from their Dark Matter Universe Energy, unable even to hear what they were discussing in their little meeting--

But for his own purposes, he could patiently play along with Joker, even tolerating a certain amount of conflict between the other's plans and his own. For example, that utterly useless William Hand. Emperor Joker had insisted on sparing his life. It was excruciatingly boring.
