Normal mindhax i don't really know, I'm not gonna go count every Hive in the Tangled Shore or something. It was once said that Oryx can't even control an Ogre without Taking it, but Hiraks has a bunch under his control🤔🤔🤔🤔
In all seriousness his normal potency shouldn't match up to multi planetary, but the maddening aspect of Hive derived stuff is still quite important. Dumping people into the Ascendant Plane is 4D.
He can kill Atro while both are in the ascendant plane, the .etch the truth of "Atro isn't here" via law manip which gets it stuck elsewhere, causing a BFR/Incap. Hiraks can also open a portal to the ascendant realm and hit Atro in there, or possibly shift it out of reality like he did to that astroid.
