BtVS by Whedon and Mutant Enemy. Marvel U by the parent company and its many artists/writers.
Basic blend of this x-meets-y critter drawn from Piers Anthony's Xanth, but a different kind of beast.
"Chère," Remy said, calmly. "Times like these, you have to ask yourself which is more important. Intimidating the unusual figure in front of you, or dispatching de pair of flying teeth headed for the back of your neck."
"Hmph," Buffy said and, without taking her eyes off the mutant, she pointed her sword skyward and took one swift step to the side.
The lone surviving demon fish passed directly through the space the Slayer's neck had occupied a moment before, with such speed that the sharp, thin edge of the sword bisected it cleanly.
The two halves of the fish went on a bit farther before falling gently apart and sliding to a halt in the grass.
Remy took the moment to rise to his feet.
##
Without his trademark boots, he would be six-foot-one.
In bare feet she would be five-foot-three.
Somehow he knew that wouldn't make her back down from a fight.
##
"Let's see," she said, smiling faintly. "Defend myself or intimidate you? Something tells me I've just done both."
Conceding the point, he returned the cards to his jacket.
"I was jus' looking for a relative of mine," he stated. "Someone who might be doin' spells here at night with a Southern flavor?"
"Can't say I have. Let me ask you, is absolutely important you find them tonight?"
"Not as such, jus' somethin' I-"
"Good, 'cause just over that hill, me and a few of my friends are trying to break into something in order to help save the world. You've just been recruited to help us."
"Oh?"
"Not to mention, that if you don't come I'll have to assume it's because you don't want my friends to recognize you or your kind and, trust me," she said with a smile and something cold in her eyes. "You won't like me when I'm suspicious."
Remy crested the hill, only to be met with the incongruous sight of a teenage Jean Grey trying to bash a hole in a wall with a sledgehammer.
He blinked and the resemblance faded.
"Wouldn't it be easier to try the doors," he asked, gesturing to the side of the crypt opposite the wall the redhead was working on.
"Sorry, no can do," said a dark-haired man sprawled in the grass. "The wall inside's thicker. Believe it or not, there was a door here, with a stairway leading down, just a bit ago. Someone messed up, the door went poof, and now we're trying to get in the hard way. Well, now that our resident strongwoman's decided to show up, we can get in faster."
"Hey, at least I was softening it up for her," the redhead panted as she set the hammer down. "Xander wanted to wait until after you got back from investigating the explosions, but I said... Hello, hotness!"
"Well, actually, it was more like 'Every little bit helps,' but I," Xander said, trailing off as he followed his friend's gaze. "Willow!" he yelled, jumping to his feet. "You're gay. And taken. And, did I mention, gay?"
"What? I can look."
"Don't be so hard on your friend," Remy said, smiling. "If you don't mind Gambit saying so, there be much to look at."
##
Rolling her eyes, Buffy walked between Willow and Remy, headed towards the sledgehammer. She paused midstep and handed her sword over to Xander.
"Cover this guy," she said, frowning. "For all we know, he's working with whomever's trapped in there with Giles."
"Now don't get cocky, just cause you've got a big stick and all," Xander said, attempting to threaten the older man. "Uh, who are you anyway?"
Remy frowned and leaned against his staff. "People keep asking me dat," he said, raising his voice over the blows of the hammer. "Each time I reply I'm less and less sure of the answer. I mean, I'm still me. I've always been me, gen'rally speaking. Just less sure of my place in the world. Can't define myself by the people who know me, if I may ne'er see dem again."
"Ah, existentialism." Xander nodded. "I get that. Try thinking that you know who you are for a night, only to wake up and know that not only had you gone for a few hours without a name, what you'd felt to be a full past was nothing but a blank slate."
"Who hasn't at one time or another? Name's Remy LeBeau," Remy said, extending a hand and a smile. "Or at least it's s'pposed to be. Y'see I was, eh, raised by a large organization that laid the name on me. I'm here in dis town on the trail of the birth sister I never knew I had. Her name's-"
"We're through," Buffy yelled, dropping the hammer to the ground with a thud.
She had time to bend down and heft a particularly large chunk of wall out of the way before the first of the spiders spilled out onto the grass.
##
Buffy's first reaction was to try and push the largest chunk of wall back in to place.
When several fangs came way too close to her hands she abandoned the effort and backflipped out of the way of the swarm.
As far as animals went, the spiders were on the smallish side, each about the size of a half-grown housecat or a particularly large rat. As far as spiders went...
A particularly large one ran directly towards Gambit and launched itself into the air with a large screech.
A kinetically-charged card met it halfway and exploded, showering that little patch of graveyard with suspiciously mammalian guts.
This didn't particularly faze the next spider, who suffered the same gruesome fate.
"Is Gambit seeing things," Remy murmured, as he aimed another card at the stairwell and the center of the swarm. "Or did dat just have a tail?"
##
"Here, Buffy," shouted Willow as she concentrated on the sledgehammer. "Catch."
Xander stayed in front of Willow, spearing any spiders that came close enough.
The hammer rose in mid-air, shook off several chittering passengers and swung itself towards Buffy. She caught it nicely and began squishing spiders around the edge.
"Now Gambit must be seeing things," Remy said, in an even lower tone.
##
Many of the spiders were trying to web the entrance shut, but each time they got close to sealing it off completely another card would fly their way, forcing them to start over.
The spiders trying to fix the wall outnumbered those on the ground by two-to-one; Remy wasn't about to let them finish the job and join forces with their more aggressive brethren.
##
"Yeah, I got a sword," Xander said in a fairly loud voice, speaking mainly to himself. "But I really want to throw fireballs. And, look at Buffy, if I was using a hammer that large I'd be swinging it half as fast." He frowned as he raised his sword to eye level. "I mean, I... Agh! It's got a face, it's got a face!"
Xander backed up a few steps, rammed the sword into the dirt and tried to scrape the impaled eight-eyed corpse off the blade with his shoe.
"Well, I'm just glad I don't have monkey fear," Willow said as she levitated a large chunk of stone until it was within arm's reach.
##
"My first day in town, and I'm fighting monkey spiders, alongside yet another telekinetic redhead," Remy said, shaking his head. "Dis is going to be a long night."
