Disclaimer: Sorry, I don't own Hellboy or the League of Extraordinary Gentlemen. I'm just a regular person- not a famous writer.

Author's Note: Comic-based. No John in this story. Quatermain isn't dead either. Also, Tom Sawyer and the Invisible man aren't in the story because Tom isn't British and the Invisible man dies in the comics (at least I think he's dead…you know how comics are).

Chapter 1:

B.P.R.D Perspective

"Kate, are you sure we're in the right place?" the blue amphibious creature said into his communicator, "Because I've been swimming in the Thames for about two hours now, and I haven't seen anything fishy."

"Abe, I'm telling you- he has to be down there. Where else could he disappear to?" the blonde girl stated into her own communicator above ground.

"You know Katie, he could have just ducked around another alleyway," the huge red demon in the trench coat commented.

"I'm telling you Hellboy, I know. I have the brains of this team and I have a hunch he's down there." Kate retorted.

"It wouldn't be the first time you've been wrong Kate," the other girl who sported long black hair and a nose stud commented. "Remember the time the toaster started a fire…"

"Liz, how was I supposed to know water and electrical fires don't mix?" Kate yelled.

"Guys, stop arguing and get your wetsuits on…I found something." Abe said, staring in awe of an extremely large red submarine.

League Perspective

"I saw it again! There it is again!" a small man with tiny spectacles screamed as he pointed out the porthole at a blue streak swimming by.

"Dr. Jeckyl, I truly think that this time you have lost it," a much older man in safari garb said. "But just in case, I have my elephant gun ready," he added, patting the bulge strapped to his back.

"Perhaps he merely saw a very large fish, Mr. Quatermain," an Indian man in a blue turban said coolly. He then went back to studying his charts. "And even if it was, I highly doubt it could breach the Nautilus,"

"Wait Nemo, I see it too!" Quatermain said peering through the porthole. "It looks almost human!"

"That's preposterous Quatermain. And Nemo, you know very well there aren't any large fish in the Thames," the pretty young lady with the red scarf scorned.

"Shut up and look for yourself Mina." Quatermain stated beckoning her and Nemo to the porthole.

"My god…I think it's coming toward us!" Mina whispered.

Nemo yelled to his crew to try to ensnare the creature and bring it aboard.

BPRD Perspective

Abe swam towards the giant devise. This must be the place where he's hiding. He thought. Kate was right…as usual.

A gigantic net that was launched out of the contraption suddenly interrupted his thoughts. In a matter of minutes, he was completely entangled.

Luckily, Hellboy, Kate and Liz were able to get to him in time. The three drew out their guns and fired. They barely managed to free Abe from the machine's grasp. Unfortunately, as they swam away victoriously, yet another net entangled the four of them and dragged them inside the ship.

Common Perspective

The BPRD found themselves in a large lavishly decorated room. Just as they managed to get themselves untangled, the men of the League walked into the room.

"What do you know? Jeckyl was right after all. There was something in the water," Nemo chuckled, "and it brought friends,"

"Who are you, asshole?" Hellboy yelled at the League, "And why the hell do you want us here?"

"First you beasts are going to answer our questions. Or else." Quartermain threatened.

"Try me pal!" Hellboy yelled lunging at Quartermain, fists ready. Quartermain only barely managed to pull out his elephant gun and shoot. To his surprise, the bullet bounced right off Hellboy's body.

As Hellboy's punch connected with Quartermain's face, Nemo quickly drew his special "harpoon gun" which shot harpoons instead of bullets and began shooting at Hellboy. Abe quickly drew his own gun and fired a bullet at Nemo, who just barely managed to dodge it in time.

Jeckyl took this opportunity to try to sneak out the room. Kate jumped in his way.

"I got this one Liz. You help Hellboy!" she yelled, sending a well-placed karate kick to Jeckyl's stomach. But to her horror, the man she hit transformed into a ten-foot-tall hairy monster: Edward Hyde.

"On second thought Liz, HELP ME!" Kate screamed as the newly transformed Jeckyl lifted her into the air.

Liz decided it was time to break out her secret weapon. Her eyes and hands glowed a reddish gold color, and suddenly Hyde's entire fur was in flames.

In the middle of all this chaos, Mina entered. "Quiet please," she said in a soft but stern voice. However, everyone continued fighting. She tried the same technique again. This time when she got no response, she did something very unladylike.

"EVERYONE SHUT YOUR PIE HOLES AND LISTEN TO ME!" a dark and deep voice came from Mina's mouth. The room shook and bats came down from the ceiling, even though they had not been there before.

Everyone simply stared at Mina, motionless and speechless.

"Allan Quartermain! How dare you joke threaten our guests! Nemo, put that gun away! Hyde, put the girl down!" she scolded. Her teammates hung their heads in shame and followed her instructions. "And you," she continued, turning to the BPRD, "explain yourselves. Why are you here?"
