Warnings: hilarity ensues.

Said feeling was entirely justified.

Wally, Kaldur and Rockabilly Punk Conner were to have the dubious honor of distracting Klarion long enough that Harry, M'gann and Artemis could corner the Witch Boy's familiar and catch it. They would then use said familiar as a bargaining chip to get Klarion to undo whatever it was he'd done to make everyone turn into their costumes. This would be difficult normally, with everyone at full strength. However, as Kaldur had pointed out, Klarion didn't know his little shenanigan had given them an ace in the hole in the form of one Harry Potter. All Harry had to do was petrify the cat and refuse to restore it until Klarion agreed to their terms.

Simple, yes; fun, definitely not.

Klarion was gloating up a storm, gleefully tossing energy around in an attempt to hit them, and it was laughably clear to Wally that the Witch Boy was just toying with them. Both Kaldur and Wally were taking some pretty hard hits in their attempt to keep the now vulnerable Connor from getting flash-fried like a chicken or worse.

He owed them. He so owed them.

Klarion wound up, spinning in the air, and gave them an unholy grin. "Playtime's over."

"You're quite right about that," Harry Potter said, everyone looking in the direction his voice came from.

The boy stood there, one hand holding the petrified familiar, and the other clenched firmly around his wand. It didn't take a genius to see that he was shaking in his sneakers, but the kid was making an effort to look as serious as he could.

"You're going to stop what you're up to, or," he paused.

Klarion, having gone from shock to amusement, leered cruelly. "Or what?"

"Or…" Harry swallowed his nervousness, straightened up and glared at the Chaos Lord. "Or I'll do to your cat what I did to Lord Voldemort."

Klarion rolled his eyes. "You don't even know what you did to him yet, do you?"

Wally face-palmed and cursed under his breath. They were so screwed.

"Oh, bullocks," Harry said, tossing the petrified cat at Klarion and raising his wand. Aiming it right at the floating statue, he shouted, "FINITE INCATATEM!"

"Idiot! That's not going to-" Klarion started, diving after his familiar.

Energy rippled out of the wand, slamming into the statue. Said statue began to glow brighter and brighter, vibrating rapidly. Then, without warning, it exploded, raining marble chunks and dust everywhere and sending everyone flying.

A moment later, Klarion coughed, sat up, and beamed in delight when he realized his beloved Teekl was no longer petrified. His joy, however, rapidly shifted into anger as he looked for the boy hero who'd been dressed as the Boy Who Lived and thoughts of all the wonderful ways he could pay him back flashed through his head.

Said wearer of the Harry Potter costume, as if realizing he was being watched, slowly stood from his crouch and unflinchingly met the Chaos Lord's gaze with bright blue eyes. He smiled, the fake glasses slipping off his face, and said one word:

"Shazam!"

Thunder roared and Captain Marvel stood there, smiling like a particularly hungry tiger.

Klarion let out a very un-Chaos-Lord-y squeak and promptly vanished.

There was complete silence for a moment.

"Aw yeah, that was so cool!" Captain Marvel said, doing a fist pump. "I can't believe I did that! Did you guys see that?"

"Good job, Captain. I thought it was you," Barry said, coughing a little as he patted the dust off his Kid Flash costume. He took off the red wig and gave it a wry smile, adding, "Wally just didn't want to hear it."

Kaldur sat up, giving a rather impolite snort of amusement at the comment.

Connor's eyes flew open and he sat up like a shot. "Where's M'gann? Where's Artemis?"

Captain Marvel scratched his head in bewilderment and then gave him a sheepish smile. "Uh, would you believe me if I said Zorro swooped in on a rope and rescued them from Klarion's evil cat?"

"Zorro?" Connor asked.

"It was awesome," Captain Marvel said, grinning. "He came out of nowhere, like a ninja!"

There was an awkward silence.

"Oh, I get it!" Barry said, slapping a hand against his forehead. "Of course. No wonder we couldn't find Robin. Zorro. Freaking Zorro. He must have been tailing us the whole time."

"Sure was," Robin said, popping up behind him.

"AUGH! DON'T DO THAT!"

AN: That's right "Wally" was really Barry. He and Wally decided to dress up as each other as a gag.
