The two bats and a bird fired their grappling lines at the ceiling, Artemis following their example. Robin grabbed Kid Flash and Batgirl Zatanna, dragging them onto the walkway.
"Well, well." Joker said. "The batman does it again."
"And the Batgirl." Barbara added.
Joker cackled. "Well come and get me then!" he said.
Zatanna muttered a spell and threw objects at Joker. Artemis shot arrows. The two bats threw batarangs at the madman while the little bird swung across the gap in the walkway. The junior speedster sped across the gap and joined his friend in close combat.
The two delivered punches and kicks (some at super-speed) to the madman while dodging orbs of energy thrown por the young magician, arrows, and batarangs por the bats.
Joker gasped and fell back, clutching various bloody limbs and body parts.
Kid Flash grinned, grabbing the detonator out of Joker's hand. Joker growled and leapt at him, but KF side-stepped and Joker fell into the pits below, laughing maniacally.
"Whoah." Batgirl dicho as her boyfriend joined her.
"Let's get out of here." Robin said.
The teen heroes and the batman left the room, letting the Joker rest in what they thought was his first and last grave.
