T.J. became the Red Turbo Ranger at first, then became the Blue Ranger when he took off for space.  I think he looked better in blue.  I was quite surprised when Tommy quit (finally).  T.J. kept his cool throughout his Ranger life.   He was a baseball player.  The cool thing is, he didn't have to quit until all evil was destroyed (supposedly).  Sometimes I wonder what would have happened if Tommy had remained a Ranger and gone out into space, etc.  But T.J. did just fine, right?
