I used to watch this TV SHOW that on on in the late 80's. I know it
only lasted a season. It was almost exactly like the movie PREDATOR
but the guy looked like he was human, until he had a fight scene
towards the end of the movie then he turned into this PREDATOR looking
monster. He had this floating eyeball that would turn invisible so
nobody could see and get money for him out of ATM machines.

Any help?

A bit late but I think you're referring to a CBS show I watched back
in the day called 'Hard Time on Planet Earth'.

From the 'Complete Directory to Prime Time Network Shows, 1949 to Present':

First telecast March 1, 1989
Last telecast July 5, 1989

Starred:
Martin Kove as Jesse
Danny Mann as the voice of Control

Description:
He was an intergalactic warrior who had been bred and conditioned from
birth to be a fighter. It was all he knew - and that was the problem.
Convicted by his society of being incorrigibly violent, he was
transformed into human form and exiled to Earth to serve "Hard Time"
until he learned compassion and tenderness, and managed to get his
antisocial behavior under control. His experiences and progress were
monitored by Control, a rookie cybernaut parole officer (which looked
like a mobile, bread box-sized disembodied eye) that offered him
advice (usually bad) and occasional assistance (generally
ineffectual). He took the name Jesse - it was the nametag on the work
uniform he had found for clothing when he first arrived - and
proceeded to wreak havoc throughout Southern California.
