Here is a walkthrough video for those who like visuals:
These characters are already unlocked for you when you bought the DLC pack. Hold to change your character; one to Darkseid and the other as Desaad anywhere in the game and the achievement unlocks.
These two characters are included with the Bizarro World pack. When you are in any level in Free Play or in any hub after you’ve completed level six, ‘The Lantern Menace,’ select Darkseid as your character. Then switch characters and select Desaad as your other character and the achievement will unlock.
Both Darkseid and Desaad are unlocked automatically so after beating Story Mode, start up Free Play and switch to both of the characters and the trophy will unlock.
