You can only find the Doppleganger after level 8. 

Beware, the Doppleganger is extremely powerful.

He has all the skills you have, has the exact same

HP and SP as you do, but he is 8 levels higher 

than you and all his stats are higher than yours 

except for HP and SP.

I reccomend you fight him 

at the end of game when all your characters are 

at level 50.  I also reccomend going to an area 

where the Lucky Animal Sleipner is located, like 

Essential Red Plum's Resort.  Find Sleipner and 

kick him.  Now wait 10 minutes, don't do anything,

don't even touch your controller.

When 10 minutes

is up, go wander around the field.  A red arrow 

will point towards the Dopplganger when you are 

near him.  A message will appear on screen, then 

the edge of your screen will be cloudy.  Run 

toward him and activate a fight.  Right when you 

start the battle, Sleipner will come in reduce 

Doppleganger's Health by half.

Now use Beast 

Awakening, be sure you have Silabus and Piros for 

this to work effectively.  Equip a broadsword and 

he should go down in no time.  However, he is able

to cast spells to heal himself, and he is 

constantly regaining HP ans SP throughout the 

fight.

By defeating him you get the Own King, a 

Key Item that transforms in one of the later 

volumes.
