Paradox, and any other faction's tokens may be obtained once you as a member join a faction. Then by completing missions, acheivements, and even just killing bad guys you will earn Tokens. Some achievements can be completed on a free accont and reward with a bag of Faction tokens. These are genaric and are not yet specific to one Faction. To use these become a member join a faction and open up the bag to get that amount of tokens.

On LEGO Universe if you join the Paradox faction and pick Space Maruder or if you join Venture Faction and pick Daredevil then you will get guns with unlimited shooting, or if you go to a Gnarled Forest vendor at the Pirate Camp then you can get a black gun that requires imagination to fire.
