The "Memphis" Assassins with manager Gorgeous George Jr.
I love old Memphis wrestling with Jerry Lawler, Jerry Jarrett, Bill Dundee, et al. I really do. They had one especially bad habit in Memphis, though: They would use the names/gimmicks of famous masked wrestlers without permission and put them on other wrestlers.
They wouldn't say "Look! It's world famous wrestler _____!", but the implication was obviously there.
In the early '60s to early '70s, Joe Hamilton and Tom Renesto were big draws in many territories as The Assassins.
There were a legendary team who cut great promos, had great matches as "technical" heels and are well remembered for their legendary feud with The Kentuckians (Luke Brown and Jake "The Snake" Roberts' father Grizzly Smith).
When Renesto retired, Hamilton mostly worked as a singles wrestler, though he did eventually form a new Assassins team with Hercules Hernandez under the hood as his partner.
In Memphis, Roger Smith (also known as Dirty Rhodes) used the Assassins gimmick in 1979-1980 and 1983 as one of many masked team gimmicks they used in the territory.
Eventually, Don Bass would join him as his partner, but first, Smith was joined by Randy "Moondog Rex" Colley and then by Bill "Kurt Von Hess" Terry. While plenty of other wrestlers worked as "The Assassin" after Hamilton and Renesto, they had more generic outfits.
Bass and Smith completely ripped off Hamilton and Renesto's look of yellow masks with black trim and either black bodysuits or yellow bodysuits with black trim. When they wore the yellow bodysuits, they even wore robes that looked like the ones Hamilton and Renesto wore when they did the same.
Meanwhile, Hamilton would sometimes work in Alabama. He opted to become The Flame there since the fake Assassin in that territory killed the gimmick. He stuck with the mask and bodysuit look, but now, he wore a red suit and a yellow mask with red trim. In 1986, Bass and Smith debuted a new gimmick in Memphis: Fire and Flame, ripping off Hamilton's Alabama gimmick. Eventually, they added Larry Wright as Torch.
Don Jardine was a major star from the '60s through the '80s as The Spoiler. Best known among modern fans as the man who inspired The Undertaker to walk the ropes and ape other elements of his style, he had a reputation as one of the best big men in the business and drew money just about everywhere he went.
The exception was the WWWF (now WWE), where he didn't wear his mask because masked wrestlers couldn't wrestle at Madison Square Garden for reasons nobody has figured out.
In 1984, Jardine was on national TV thanks to the Georgia promotion's exposure on TBS. That didn't stop Lawler and Jarrett from giving the name to Frank "The Angel" Morell, another area mainstay. With Jardine on national TV and Morrell looking nothing like him in the outfit, he didn't come off as a straight-up "fake" like The Assassins did in Memphis.
Tim Woods was an amateur star who broke out under a mask as Mr. Wrestling. Later, aging journeyman Johnny "Rubberman" Walker became a big star as his partner, Mr. Wrestling II, in his iconic white mask with black trim. Various other Mr. Wrestlings popped up everywhere to ape Woods, with Memphis using another local veteran in the role.
Tommy Gilbert (father of Eddie and Doug), like Bass and Smith, used a lot of masked gimmicks in the early to mid '80s. In 1985, Mr. Wrestling became one of them in the promotion now formally known as the CWA.
Later that year came possibly the oddest of these cases. Jerry Stubbs came in to the CWA as The Masked Superstar, a gimmick made famous by Bill Eadie (AKA Demolition Ax and The Super Machine).
Stubbs was already a star under a mask (which he used often to hide his prematurely balding head) as Mr. Olympia in many southern territories. He looked nothing like Eadie, only wearing the same style mask and not trying to co-opt the rest of his look, much less his wrestling and talking styles.
He was out of the territory pretty quickly and went home to Alabama as himself, taking on the nickname "Mr. Perfect."
And before you ask: Yes, some people claim that Curt Hennig asked for Stubbs' blessing before he became Mr. Perfect in the WWF.
