Becoming a Russian citizen won't make Roy Jones Jr. the Kremlin's most feared fighter ... 'Cause Dolph Lundgren says his "Rocky IV" character Ivan Drago would kick RJJ's ass.
Lundgren was out in Beverly Hills when we asked about Vladimir Putin recently granting Jones an honorary citizenship during a ceremony in Moscow.
That's when Dolph hit Roy harder than Drago hit Apollo ... cause when our guy asked if Roy could take the fake Russian killing machine ... Lungdren talked some real smack.
Check out the clip ... and RIP Apollo Creed.
