Synopsis for Supergirl: "Return of the Black Flame"
Supergirl is contacted via news station by a mysterious person who asks the Maid of Might to go to a specific home address because she is the only person who can help her out. Supergirl heads to the place, not knowing it is a trap of her old enemy, Black Flame.
Black Flame broke out of jail in Kandor and left the Bottle City, managing to enlarge herself afterwards. She then acquired a spaceship, went to a warp portal in the Phantom Zone, and took on three super-criminals from the Phantom Zone: L. Finn (a leprechaun), the Toymaster II and the Inventor. She then tricked Supergirl into coming to the house which they use as their headquarters.
Kara realizes too late it is a trap, and is sprinkled with Green Kryptonite. Rather than waiting until the Kryptonite dust takes effect, Black Flame orders her subordinates to take Supergirl to a room where she can torture her before killing her.
Supergirl comes to and sees she has been made to be a "pin" in a bowling alley with Green Kryptonite bowling balls. The Phantom Zone criminals throw ball after ball at Supergirl. However, although she gets hurt, the constant battering shakes the Kryptonite dust off the ropes binding her. Kara manages to free herself and attack, but one of the allies of Black Flame is some kind of sorcerer and freezes her.
Then she is placed in a deathtrap with Gold Kryptonite slowly stealing her powers, and a Green Kryptonite spear is set to be launched through her body once she loses them entirely. But Supergirl manages to reach a remote control for Toymaster's minature robots and uses them to cut her free. She recovers her powers once she is away from the Gold K, and uses the toys to capture the three Phantom Zoners while she herself takes care of Black Flame. Later, Black Flame is taken back to Kandor and the three other villains are returned to the Phantom Zone.
