In the Ultimate Marvel Universe, Captain Britain is a member of the European Defense Initiative (the EU equivalent of the Ultimates), along with Captain Italy, Captain France, Captain Spain and several unnamed members most likely from other European countries, all of whom have the same powers: flight, super strength and a force field. All four of them developed their powers from the super powered exo-suits developed by Professor Sir James Braddock, who oversees the EDI super soldier program. Captain Britain and the other members of European Defense Initiative helped the Ultimates track down and contain Thor and they released the Fantastic Four, Spider-Man and the X-Men during the Liberators' attack on America. They are also seen helping to pull up the Statue of Liberty after the battle is over.
