Fang Bei Fong Set post-finale. Written in revenge for not pairing Toph with anybody. REVENGE! Ahem... Sorry.

Chapter 1: Going-Away Present The Gaang was all together at the Jasmine Dragon. Katara and Aang were off being lovey-dovey, and Sokka and Suki hadn't even bothered to go somewhere else. Iroh was calmly sipping tea.
And Toph was pissed. Nobody had bothered to hang out with her, which left her with nothing to do but earthbend or pick on Sokka. And Sokka was busy, and even though Suki didn't deserve him, he deserved to be happy right now.
She sighed, blowing hair out of her eyes. She felt around her through the earth, looking for something to do. Outside, growling could be heard. She got up and walked out to get a better feel of what was going on.
Several men had crowded around a group of dogs, who were busy tearing into one particular dog. Betting was going on, with some men placing bets on how long the loner would last or even how many would be taken down before the dog went down himself. Toph had felt similar fights before, but this one pissed her off. She and her friends had just liberated the world for peace, and these men wanted to cause fighting? Not on her watch! Er... you know what I mean.
She stomped, sending dogs and men flying. The few that were left earned harsh kicks as they scattered. She stood above the animal as its heart began slowing to its normal rate.
Wait, this was no dog. She could feel the nobility in its stance. This was a wolf, a true wolf that had somehow been cut down by these men who had pitted it against several ruthless enemies. Despite its wounds, she could feel it gazing on her, as if daring her to go, "Aw, poor thing"
She smirked. "I ain't gonna fawn all over you, bud. You're too tough for that"
The wolf barked as if in agreement. Toph laughed.
"You're pretty smart. Hey, see you around"
The wolf cocked its head to one side and woofed, as if asking her something.
"What?" She turned back to it and reached out through the earth. That wasn't neccessary, though; the wolf's stomach growled almost as loud as Sokka's.
"All right, all right, we'll get you some food"
She began walking back inside. The wolf fell in behind and to the side of her, his carriage almost suggesting he was escorting her instead of her leading him. The two walked in to find pretty much the same situation as before.
Toph yelled, "Hey, Snoozles, Fang gets your meat"
Sokka was oblivious to even the threat on his meat as he and Suki made out on the couch.
The wolf tilted his head at Toph and woofed a question.
"Fang Bei Fong. You like it"
He appeared to think for a moment, then grinned and touched her hand with his nose. She responded by rubbing behind his ears.
"You're all right, Fang. Much better than Snoozles and his never-ending chatter." Despite herself, she sighed. She actually kinda missed that chatter.
Fang nosed her hand again, just as his stomach growled again. Toph snickered.
"Geez, Fang, your stomach carries on almost as much as he does"
Fang gave a low whine. He placed his paws on the table to look on it, then dropped down and walked over to a seat. He jumped up on it and sat, almost as if waiting to be served.
"Now you should know that's not allowed"
At this point, Katara and Aang returned. "Hey Toph, who you talking - oh. Who's this"
As the scent from the two washed over Toph, she wrinkled her nose. They had obviously been swapping spit in the past few minutes.
Fang gave a snort, as if he shared Toph's opinion on her friends.
"Well, lovebirds, this is my new friend Fang," Toph told the pair.
"Cool dog!" Aang said in his overly cheerful manner. Fang gave a sharp bark and a growl. Katara almost water-whipped the wolf, but Toph yelled, "Don't you dare!" bringing an earth wall up in front of Fang.
"He's no dog, he's a wolf! Obviously that's what he was saying to Aang"
"Still"
"Katara, it's all right," Aang said to the irate waterbender, then turned to Fang, bowing. "My apologies, friend. I was mistaken"
Fang dipped his head in acknowledgement.
"Wow. I didn't think he'd do that. He seems different from a normal wolf"
"Well, duh, Twinkletoes, he was forced to fight dogs just to stay alive!" She went on to tell them how she had met him.
"Wow." Katara also bowed in acknowledgement of the wolf's hardship. She nervously reached a hand out, stopping short of actually petting him. "May I?" she asked Toph.
Toph shrugged and looked over to Fang. He responded by nosing the hovering hand, allowing it to rub down his snout. She continued to pet him as she said, "I wonder where he comes from"
Aang gazed at the wolf, who returned his gaze in full. "Maybe he's a spirit wolf. Can you bend, Fang"
Fang seemed to droop in disappointment.
"Oh. Sorry"
Katara leaned down to hug the wolf, in order to comfort him. He immediately jumped away and started growling, then backed away from the waterbender.
"Fang? What's wrong?" Toph asked.
The wolf growled in annoyance, as if to say, "Hello? Mute here"
"Dangit! I wish I knew what was wrong"
The wolf slowly circled around the table before taking refuge behind Toph. She let her hand dangle to lightly brush his back. He nosed her leg, then circled around Toph and sat, an irate gaze leveled at Katara.
"What did I do?" Katara asked plaintively.
Toph sighed, then snapped, "Obviously he has a problem with that much physical afffection! Not everyone's as touchy-feely as you, Sugar Queen"
"I think maybe he was captured that way," Aang added.
At that moment, Sokka and Suki decided to interrupt. "Hey guys, what's goin - OMIGOSH, IT'S A WOLF! THAT'S SO COOL!" Sokka yelled. "HEY, WE SHOULD GIVE IT THE BEST FOOD EVER - MEAT"
Sokka was a lot more cheerful than usual on account of defeating the Fire Nation and being with Suki. Fang responded with an enthusiastic bark as he raced to the warrior and jumped on him, placing his paws on Sokka's waist.
"Fang?" Toph asked, a little worried that Sokka would be pissed at being jumped. She need not have worried.
"His name's Fang? That's so cool! Come on, Fang, I got some rabbiroo we can share"
Fang barked and followed Sokka as he ran to the table and grabbed a helping. He knelt down and offered it to the wolf. "Here you are, sir," he said, using his Wang Fire voice.
Fang cocked his head to one side as if confused by the voice change, but quickly grabbed the meat and began eating. Unlike most dogs, he didn't tear into it; he carefully picked away at it so no meat was thrown around or wasted. He finished quickly, then yawned. The rest of the group finally noticed that it was getting pretty late.
"So, Fang, you staying?" Toph asked.
Fang once again nudged her leg, then circled her. He then stood by her side, as if waiting to seee where she would lead. The Gaang went their separate ways, with Toph now being accompanied by her newfound friend.
