What do you mean you don't know where you came from?
The RKO was one of the most popular and deadly moves in the professional wrestling world back in the reign of a WWE superstar, Randy Orton. After his retirement and so many years, since WWE was not as lively as before, even the move RKO, itself, had been forgotten.
Arnold only got to recognize it because of his research and videos he had watched from old capturing. Truth be told, he had loved this finisher, but he never thought he could get to use it.
But now that the system had given him that privilege, there was nothing that could stop him from using the finisher.
"That's really cool... I can't wait to RKO Jerry Blaze next week, hehe," Arnold chuckled excitedly.
