Nefir Hasenuf's Fate
The scheming imp's final appearance is in the episode "the Way We War". After being made to refund all the money he took, repair all the damage and dismantle all that weaponry, we don't know what happens to Nefir and his imp minions. Executing him would probably go against Aladdin and the Sultan's moral compass; they probably did not want him imprisoned in Agrabah either (he could plot some kind of revenge or takeover). It is highly likely that the Sultan banished Nefir Hasenuf from Agrabah forever with Genie backing that up with some sort of comical threat, even impersonating
Dirty Harry or
The Terminator.
