*Hello, lovely WonderBat people! It's me, Maven Alazais again. I just can't seem to take myself away from this pairing! So, this fic is going to be short and supposed to be funny. I just want this to be happy and not dramatic, so if you're looking for something more serious or tear-bringing, go through the rest of my WonderBat fics. Anyway, thanks for joining me here and I hope you like this!

PS.: Based mostly on the JL-JLU cartoons, with some other DC additions like Nightwing.*

FOREIGN ANATOMIES

CHAPTER ONE – THE SWITCH

Diana couldn't help herself but admire the building. Though quite indifferent on the outside, the inside was amazing. Well, nothing less from Circe's own hideout, she thought. How could an immortal sorceress reduce herself to something simple?

They had been working on finding her hideout for some weeks now. She had expected it to be easier, but it wasn't. Luckily, Nightwing had managed to come up with an algorithm, combining the range of Circe's magic and the reoccurring appearances of Beastiamorphs around the globe. In just a few days, they had spotted the place.

Batman, Green Arrow, Doctor Fate and she had been dispatched for apprehending the witch and her slaves. As they moved forward, through the lush corridors and rooms, more and more Beastiamorphs tried to stop them, unsuccessfully of course. Doctor Fate and Green Arrow went to check a room on the left, while Batman and she kept moving down the corridor. By its end, they entered a big, marble-paved room with high columns reaching the top. Though it was empty in the middle, all around the walls, smaller inner balcony-like structures were holding big cauldrons and the Beastiamorphs working on them. As soon as they were noticed, the beast-like men jumped down the 'balconies' and charged.

Diana untied her lasso and flew over some 'Minotaurs'; Circe's favorite Beastiamorphs. Capturing one, she easily picked him up with her lasso and hit the rest of the incoming ones, much like bowling pins. She finished those still moving with a few punches and placed some unruly hairs behind her ear. She turned around and saw Batman fighting with another Minotaur, having dealt with five of them, she counted. Her eye caught a small movement from above; a Beastiamorph had climbed back up and tried to push the large cauldron on Batman.

With a strong push, she propelled herself forward, flying to the other side of the room. Just as the Minotaur rival was falling to the ground, she managed to push Batman out of the way. The cauldron hit her instead and she fell down.

Batman didn't know why she had pushed him at first. He should have guessed, though, he thought, when he reopened his eyes and saw Diana under the big, black cauldron. The peculiar bluish liquid was oozing, giving off a lavender smell. Diana picked herself up, pushing the cauldron away and growling loudly. She huffed and her eyes shone in anger. She was soaked wet and the sticky liquid was dripping from her hair and her…everything; fingers, legs, back. The Beastiamorph that had dropped the cauldron jumped from the 'balcony' and before it couldn't even land, Diana sent it flying to a wall with a perfectly executed roundhouse kick.

Bruce couldn't help but half-smile a bit. The sight was indeed, rather funny. Diana was shining blue and the smoke of the liquid made it look like her head was on fire.

She cursed something in Greek and turned to him, stretching her hand. He took it and stood up. "You didn't swallow some, did you?" Bruce asked, resuming his serious face and shaking his hand off.

"No."

"You should get checked in at the hospital ward for precaution. We don't know how this potion works."

"I feel fine. Maybe it's some sort of…basis for other potions and no weird ingredients were inside."

"Get checked either way."

"Yes, I will, do not worry. Let's go find the others, maybe they found Circe."

Batman nodded and they left. He took a look at his hand; his enhanced glove had been scratched. Those Beastiamorphs were certainly enhanced as well, to be able to scratch that, he presumed. The fabric hadn't been altered by the potion that came in touch with it, so he came to the conclusion that it wasn't corrosive at least; Diana's suit and skin were both more resilient than ordinary human skin and clothes and it would take time to see it get through on her.

As they exited through the corridor they had entered before, sounds of battle came to their ears. Diana flew ahead, following the sound, and Bruce ran behind her. Soon, they reached what appeared to be the main room; Circe's hold. In the middle of the room, levitating, Doctor Fate was battling telepathically with Circe. Yellow and pink psychic rays were shooting around, as they both tried to subdue their opponent. Green Arrow tried to hit Circe but she managed to withhold a force field that repelled everything.

"Batman!" Diana called and Bruce nodded at her meaningfully. He reached for his belt but before he could take what was inside out, his knees failed him and he fell to the ground. Wonder Woman came to his side and shook him lightly. "Are you okay?!"

"Just take it!" He shouted, coughing. Diana reached for a small pocket of his utility belt. She took a small leather pouch out and losing no time, flew to Green Arrow. When Circe was down, she would check on Bruce again. He wasn't hurt, so she really thought it weird that he fell down like that.

"Give me an arrow!" She told Green Arrow and Oliver handed her one out of his quiver. Diana took a plant residue out of the pouch and rubbed the tip, giving it back to him. "Shoot."

Green Arrow took aim and let go of the arrow. It shoot straight through Circe's field, hitting her armor. The moment it hit her, Circe was also hit by one of Fate's rays and fell to the ground. Green Arrow ran to her and put her in handcuffs before she could wake up. Diana rubbed some more of the ointment on Circe's arms and ankles.

"That should do it." She said, realizing the sides of her vision field were getting blurry.

"Moly*, uh?" Oliver asked and she nodded drowsily. "What happened to you? Took a shower or something?"

"Some sort of p-potion…" Diana started saying before she fell to the ground too. Before she lost conscience, she saw Circe open her eyes and look at her. The sorceress cracked a wide smile, taking a look at her soaked body.

"I hope it's one of the Beastiamoprhs!" She mouthed.

OOO-OOO-OOO-OOO

When Diana reopened her eyes, she recognized the walls of the hospital ward and sighed. The potion wasn't so harmless, she guessed, remembering that she had blacked out.

Something felt weird, though. She couldn't really pinpoint what, though. Physically, she felt fine, she wasn't aching. She was just feeling peculiar, as if her body was out of its limits, or… She didn't know how to describe it. She pulled her hands in front of her and shrieked at the sight of them being bulky, way hairier than hers and most definitely manly. She threw her head left and caught her reflection on the wide windows. This wasn't her! This was Bruce, not her! She started kicking her sheets furiously, lifting herself up. She turned right and saw what was her body alright on the next bed. 'She' was having her fists clenched and an extremely grave expression on her face.

"Wakey wakey, Princess." Diana heard her voice, from her body, say.

"What's going on?!" She said, watching the Diana opposite cringe a little. What came out of her mouth was just a high-pitched Batman voice.

"Guess."

Diana swallowed dryly. "W-We…switched souls?"

"More or less. The potion you fell into was a bodyswap formula."

"Oh, crap." Diana swore. "What now?!"

Bruce in Diana's body shrugged. "Circe's just laughing at her cell. She says she knows no antidote."

"Liar, obviously!"

"We'll see." Bruce said, trying to fold his arms and exhaled loudly. "How do you people move with these things around?! Damn it!"

Diana laughed. Bruce, in her body, trying to struggle with a full breast was funny, no matter how serious the situation was.

Bruce's eyes widened at sight of his own body bursting into laughter. His face was weird, the sound was weird too, the laughter wasn't even his. It was Diana's, but amazingly fearsome, coming out with his voice and facial expressions.

The ward's door opened and in came Green Lantern and Flash.

"How are you feeling, Princess?" Green Lantern asked.

"I've been better!" Diana replied, still inside Bruce's body. Green Lantern nudged Flash and they laughed loudly. Bruce frowned deeply.

"Ugh, man, hearing Batman respond to 'Princess' is better than I thought."

"Cut it out." Bruce warned.

"Sorry, Bats." Flash said. "It's way too funny to leave it. Tell me, do you think I stand a chance with you in Diana's body?" He wiggled his eyebrows. Bruce simply looked at him coldly, starting to admire Diana more for hearing things like that on a daily basis and not going on a rampage.

"Please, tell me you found an antidote." Diana said.

Green Lantern shook his head. "Nothing so far. You can try the magic lasso on Circe when Princess over here"-he looked at Bruce-"is ready." Bruce growled in frustration.

"Hey, Diana," Flash said with a playful grin, "aren't you curious how you look under those hospital robes?"

Diana smiled mischievously, and both their visitors giggled at the sight of Batman grinning like that. "Maybe I am…" She slowly lifted the covers off.

"NO!" Bruce shouted, jumping off the bed. That sudden movement dragged all of his tubes and a part of the wall as well along. Bruce was drawn back by the cement block and fell to the ground with a loud thud, causing small cracks to appear on the floor.

"Super strength. I forgot." Bruce mumbled. Flash lightly kicked the side of his leg, closing the gap between his legs.

"Lady parts too. Don't forget."

"Oh, so, flashing man parts around is acceptable?" Diana asked, throwing the bed sheet off. She placed her hands on her robe, pretending to be tearing it apart. "I've been waiting for this my whole life! Finally free!"

"No!" The three of them shouted simultaneously and Diana grinned at them meanly. They all cringed again; Batman smiling in any way was creepy every time.

Diana let go of her grip. "Good to know…"

"If you don't leave now," Bruce warned, acknowledging how menacing he sounded, even with Diana's voice, "I will use my super strength."

"We'll be back, tough guy." Green Lantern said, tapping Flash's shoulder. "See you around!"

Bruce brought himself up and sighed. He turned to Diana, or rather, his body. "We've got some things to sort out."

"You bet. How did that potion even work?! I'm baffled. Why you?"

"I'm guessing it works out of physical contact."

"When did I ever came into true physical contact with you?" She asked, mildly implying several things that Bruce decided to ignore for the time being.

"When you stretched your hand out for me."

"I only ever get to touch your glove."

"It was torn. Some of the potion you were covered with slid inside."

"Oh… That's why Circe whispered 'I hope it's one of the Beastiamorphs'."

"When did that happen?"

"Shortly before I lost consciousness myself. It makes sense. Imagine the drive of a Beastiamorph in my body."

"Indeed."

"Why didn't it happen instantly, though? I thought potions worked immediately."

"With my short knowledge on sorcery, I'd say that's not certain. Besides, you were practically bathed into it, while I simply touched half a drop."

"Yes. You're right. Now, into more practical matters…"

Bruce tensed up at the thought of those.

*Moly is a herb, known to cancel Circe's powers.

So, this was the prologue-intro of this fic! It will be a short one and hopefully funny! Please leave me a small note on how you found it! Thanks for reading!*
