Currently, it is debatable if the IronFist is being wielded.

You will obey the fist.

Miss Bitters: ZIM, the machine says that the only career you are suitable for is--
ZIM: Yes, yes, LORD OF HUMANS! I will rule you ALL with an IRON FIST!
Miss Bitters: No, ZIM, the machine has assigned you a career in fast food preparation.
ZIM: ...I will prepare food with my iron fist! Then I will work my way up to ruling you ALL with my fist! You! Obey the fist!
