You place Burn tokens from Defeated Enemies in the Adachi Asylum to lock them up!
Burn tokens from Villains are placed at the left side of the Asylum and tokens from the Supervillains - at the right side of the Asylum.
Once TWO Villain Lockup spaces are filled, all Villain cards will be removed from the top of the Enemy Deck and Supervillains will start appearing.
Once TWO Supervillain Lockup spaces are filled, the Menace card chosen for the game is placed on the top of the Enemy Deck.
Once the Menace is added into play, Supervillains will still continue to come into play after each Crime Time.
