does anybody know the name of the multiple image >technique cologne
used in the anime?  or any similar technique?

	I don't think it's ever named, I do know about a Dragonball technique 
that translates as 'one patern'.  Goku and Kuririn learned this technique by 
training with 90 pound turtle shells on their backs.  When the shells were taken 
off they improved to the point where they could move at a speed that left 
afterimages of them behind.  At first they could just create one afterimage, 
later goku improved to the point of being able to create three.  Oh, and all 
this preceded Dragonball Z.
