[1] Kruschev left JCP in December 1986 (to go to the WWF as Smash of Demolition) and Ivan replaced him with Vladimir Petrov to get Nikita.
[1] In 1988, Ivan Koloff and his manager Paul Jones recruited two masked Russian Assassins to feud with Nikita.
[1] However, the Assassins and Jones turned on Koloff after he lost a Russian Chain match to Ricky Morton at Clash of the Champions III: Fall Brawl.
[1] After the Assassins attacked Nikita and put him out of action (in reality so he could tend to his unwell wife Mandy), Ivan replaced him as a tag partner with former rival Junkyard Dog.
In late March 1989, Ivan and one Assassin left the company while the other continued in WCW without his mask under his regular ring identity Jack Victory.
