TV episodes and the movies of Dirty Pair...)

Check out the OAV "Flight 005 Conspiracy".  Also, remember that I drew 
a bit from the comics as well.  Lastly, in my defense, remember that 
the deepest characters in my DP fics were always my own: Lord Robin, 
Tarc Meridian, and Andrew Fisher, for examples.
