Palpatine in the MCU
So the Jedi of the PT era discover Palpatine's plot to take over the Republic and commit genocide against them. They manage to overpower & render him unconscious. With some help from their scientist friend Jor-El of the planet Krypton, they seal Palpatine inside the prison ship the Black Zero. He makes a couple of orbits around the galaxy, but along the way, the ship enters some kind of wormhole and enters...The Marvel Cinematic Universe.
Palpatine lands on MCU Earth with nothing but his lightsaber(Some dumb thing about not leaving a warrior without his weapon or something like that) just after the events of The Avengers.
Palpatine lands on Xandar with nothing but his lightsaber during Ronan The Accuser's invasion during Guardians of the Galaxy.
How does he do climbing the ladder of power and rebuilding his world/galactic domination schemes in these new worlds?
