‘Vader’ won the primaries of the UIP, his group said in a statement and was officially proposed for the candidacy on Saturday.
“I alone can make an empire out of a republic, to restore former glory, to return lost territories and pride for this country.”
Ukraine's presidential elections will take place on 25 May.
Vader and other activists also dressed as Star Wars characters including Stormtroopers, have previously made appearances on the Ukrainian political scene.
In December 2012 they distributed canned foods, matches, condoms, toilet paper, soap, lightbulbs and ‘tickets’ for their spacecraft evacuation scheduled for the supposed end of the world – 21 December.
Vader also made a bid to become mayor of Odessa late last year – after being carried into the city hall by Stormtroopers.
The UIP was registered as an official political party in 2010 and aims to create an electronic government in Ukraine, facilitate the transition to digital media and offer free computer course to all citizens.
