The bulk of his career took place in Australia where he was an instant hit with the Greek population there. Arion actually was popular with Aussies of all kind and a case could be made that he was the top wrestler there for a decade. He held the top championship of the major Australian promotions on nine different occasions often defending the territory against other wrestlers who would “invade”.
Spiros Arion would have his most known run when he returned to the WWWF (he competed there in the late 60’s) as a protégé of Bruno Sammartino. He turned on Bruno and the two tore the house down at MSG. He was a great heel in America and had he competed in the U.S. more than Australia, his profile would be significantly higher than it is today.
