The Vbulletin Plugins works on MyBB?
No they will not. Completely different systems, hooks and so on.
Plugins need to be specifically programmed to work with either and if mybb were to somehow work a hook for doing this they would run the risk of infringing vbulletin licensing
What about the themes of Vbulletin will they work on mybb?
