Smoking Rockets, We Need to Call All Space Rangers Now! (AKA: Space Police Force)

In the the 1950’s, there was a TV series called Rocky Jones, Space Ranger (1954) and Space Patrol (1950) that patrolled the galaxy enforcing law and order, and fighting outer space evil long before Starfleet and the Jedi ever did, but away after Flash Gordon and Buck Rogers has already started. There was another short lived six episode series that appears to be a remake of RJSR called Space Rangers (1993). Using the concept of marine or navy military types mixed with lawmen, and, also maybe, with a degreee in science or medicine, but definitely with extensive experience in space travel, who would you choose to be your mentor should you choose to be a new recruit of an interstellar police force patrolling the lawless outer frontier regions of space?

But animated is not are not excluded just as long as they fit the description above. NOTE 2: Since Space Rangers (1993) and BraveStarr (1987) are not widely known, a character description may have to put into their entries.
