You were on the right track, the Dark Archon can permanently mind control another unit, including SCVs, or Zerg drones thus enabling you to build a command center, or zerg hive of your own. Arbiters have the ability to put enemy buildings in statis, temporarily "shutting them down".
Other than that, the zerg queen can infect a terran command center once it is sufficiently damaged. The infected command center will then produce a type of kamikaze unit called infested terran.
