G-black
you must have g-red in the first spot in the gotchabox a normal ninja to his right and a revolver gunner to the ninja's right.
put the ninja in the 2nd,4th,6th,10th,11th force
then head to the 20th Force and put G-red in the 23rd slot then put the gunner in the 15th slot pick an empty space in the box click A it will be "grabbed" put it over the ninja click A press B NOTE:Some borgs will apear in random places in the Force don't worry this is supposed to happen.grab the ninja in slot 24 put it over the G-red in the 15th slot after you pick it up press B then grab the same empty space you chose then put it over the arrow ninja then press B the space will be dropped and you can now use G-Black!
Galactic Emperor
do the same first steps except put the ninja in the 3rd,10th,11th,12th Forces then due the same final steps and you should now have The Galactic Emperor but the game will freeze if you screw around to much with it.
