A/N: Ditto.

Update: Spelling error fixed.

Spy quickly made his way inside the same way he got out and breathed a sigh of relief. He was glad that he did not get torn to pieces like his BLU counterpart, but wondered who or what attacked the BLU Spy.

A consistent barking interrupted his thoughts. He looked down to find K-9 pawing at his pant leg. Spy couldn't help but to smile at the sight as he knelt down to the dog and scratched under its chin.

"Shouldn't you be sleeping?" he asked before getting up and walking towards his room, unaware that he was taking to the perpetrator.

K-9 tilted his head as Spy walked off before walking towards the couch and finding a nice place to lie down and sleep.

The following day was rather uneventful for either teams, and soon Monday rolled around, which meant more fighting in the hot desert. Today's battle will be another Payload escort, but this time on the desert mountain, Upward.

"For the last time you two, we cannot bring K-9 with us," said Debbie.

"But whyyyyyyy?" whined Tia.

"He's only a pup, Tia," said Stella as she checked her machineguns. K-9's age is around the normal pup age, however he is quite large for a dog his age, so some often mistakes him for a full-grown dog. "Besides what can he do to help us out?"

"Ah, sniff out Spies?" Tia suggested.

"Recon?" added Tai.

"Annoy the shit out of Scout?"

"You know I actually want him to do that last one," Stella whispered to Debbie.

Debbie sighed. She knew how much the twins loved K-9 and knew how persistent they were in getting what they wanted.

"Fine you can bring him,"

"YAYYYY!"

"BUT…you two hafta keep an eye on him to make sure he's ok,"

"Ok we will Deb!" the twins said in unison before teleporting away.

"Is this the first time we've ever heard them say something in sync before?" asked Stella.

Time Skip

Today's battle was not as easy for RED as Friday was. BLU put more resistance when attacking, and targeted the buildings whenever they were spotted. But never less, each side put up quite a fight.

The cart was nearing the second to last checkpoint. RED knew that if they did not stop BLU here, then they had the chance of pushing the cart to the final checkpoint. Stopping them here would allow RED to win the battle.

"WHOA!" said Stella. She peeked around a corner only to find a bullet heading straight for her. She quickly pulled her head back as the bullet hit a wall. "WHERE IS EVERYONE?" she shouted to Tai.

"RESPAWNING!" shouted back Tai, who fired a wild shot at the advancing BLUs. "Debbie's with Soldier and Demo trying to flank them!"

"Bullshit," she said as she launched a rocket at the cart pushers. The explosion sent the BLU Scout and Medic off the side of the cliff. Tia appeared next to Stella with Medic and Heavy.

"Here's your stop," she said before disappearing.

"You three can handle this," said Tai. "I'm going to see if I can disrupt the Teleporters in the backlines,"

"GO!" shouted Stella as she ran into the fray with Medic and Heavy.

"Lets go K-9," said Tai as she picked up K-9 and disappeared.

The two appeared near BLU's spawn in the tunnels. With K-9 watching her back, she peeked around a corner so she could see BLU's spawn.

What she saw was only one, active BLU Teleporter.

Motioning for K-9 to follow, the two made their way to the Teleporter. She raised her shotgun to destroy the building when the cocking of a shotgun stopped her.

"Shit," she thought as she turned around. She found the BLU Engineer and Soldier standing behind her and K-9 with their weapons drawn.

"Well look what we have here," said BLU Engi.

"I WILL NOT BE HUMILIATED ON MY BATTLEFIELD AGAIN, DO YOU UNDERSTAND THAT?" BLU Soldier shouted.

K-9 snarled at the two before blindly charging the two men.

"K-9 NOO!" shouted Tai.

"Mangy mutt," muttered BLU Engi as he pulled the trigger.

K-9 staggered a bit as he was shot, but continued to charge the two. Both BLU Engi and Soldier let out another round of gunfire at the dog, which somehow ignored the pain. But K-9 was too weak as he got close to the two and instead stumbled and fell to the ground, bleeding and breathing heavily.

Tai was in tears when she saw K-9 fall. She wanted to check on the dog but couldn't. "You…monsters," she managed to croak out.

"Aww, now you don't look like a happy camper," said BLU Engi. "Don't worry you'll be joining your dog friend very soon,"

Meanwhile

K-9 was watching the entire thing with one eye as he lied on the ground bleeding. He wanted to do something to help out Tai, but couldn't. He saw tears streaming down Tai's face as the two men closed in on her. His eyes started to close, but not before his vision turned red.

Just as his eyes closed, it opened back up, now shining a bright red. His wounds started to heal, and he started to get his strength back. He started to grow in size once again, and his bone structure shifted from being quadruped to bipedal. His claws sharpened as well.

When the transformation ended, K-9 looked to be a tall and muscular anthropomorphic German Shepard. He had his red bandana around his neck, and his body armor turned into a similar looking one made for this form. His eyes glowed red and brightly shone in the somewhat dark tunnel.

The three were unaware of K-9's transformation going on behind them. And he used this to his advantage by grabbing the Texan by grabbing him by a leg and tearing him in half, bottom up.

BLU Soldier turned to find his friend torn apart by a large creature. He turned and fired a shot, but the creature dodged the shot and lunged towards Soldier. It let a clawed hand sink into Soldier neck and pinned him to the rock wall.

K-9 let out a huff as he pulled his hand out of Soldier and the wall. Soldier's head rolled to the ground as he did so. K-9 looked at the bodies of the two dead BLU merc until a voice broke the silence.

"K-9?"

K-9 turned his head to find Tai, stunned by the events that unfolded in front of her. He walked over to her and bent down to pick up her shotgun she dropped. He handed it to her, before saying,

"Lets finish this,"

This surprised the both of them. And led to an uneasy silence.

"You can talk?" she asked. "Ok this is the weirdest thing ever since we've became humans,"

K-9 shrugged before absentmindedly picking up a random organ on the ground and biting into it like an apple.

"Ok, that's gross," she said while facepalming. "Stop doing that,"

Meanwhile

The REDs only had to hold off the BLUs for another two minutes. Stella stood behind cover while she reloaded her machineguns.

"Stella!" shouted Debbie as she ran up to the sentry. "Do you know where's Tai?"

"Backlines sabotaging," Stella said calmly.

"WHAT!" Debbie shouted. "Tell me she has Tia with her,"

"Who has what now?" said Tia as she reappeared with Demo and Sniper. "Hey have you two seen Tai?"

"Stella, tell me she has SOMEONE with her," said Debbie.

"Does K-9 count?" Stella asked sheepishly.

"You gotta be shitting me right now," she turned to Tia. "Come, we're finding your twin,"

Before they could go Scout ran up to them, "Um, I think you three should see this," he said before turning and running away. The three turned to each other, confused, and started after Scout.

What they saw was shocking.

They saw a tall and muscular anthropomorphic German Shepard currently taking on the entire BLU team. The REDs were currently unsure what to do, either to watch or help out the BLUs. Bullets, rockets, grenades, even backstabs were not having any effect on the creature. They watched as the German Shepard killed each BLU merc one by one.

"What the fuck is that?" Debbie asked.

"That would be the puppy that you didn't want us to bring," said Tai who appeared next to the three.

"Wait, that is K-9?" asked Stella. She whistled. "And I thought I saw it all,"

Despite being pounded from all sides, K-9 never let up as he took down each BLU merc. The only two mercs left was a BLU Heavy and Medic.

"I am fully charged," said BLU Medic with a grin.

"Hahahaha! IT'S TIME TO RUN COWARD!" said BLU Heavy as he and the Medic were covered in a blue shield.

K-9 responded with a roar and a red flash engulfed him. When it faded away, he too was Ubercharged.

"That's…new," said Tai.

"Did he just Ubercharge himself without a Medic?" asked Debbie. "But isn't that almost impossible?"

"Well, I guess not," said Tia.

K-9 charged the pair, and, using his arm, stabbed BLU Heavy through his shielded body. From there he stuck his other arm in and ripped the Russian into two. BLU Medic gasped as he saw his patient die even through he was ubered. He didn't have much time to think as a punch sent his head flying off into the distance, his body then crumpled to the ground.

K-9 observed the carnage he created as his uber wore off. He was breathing heavily and blood stained his hands and body. Before he could do anything, his vision started to darken and he slumped to the ground.

Thanks to K-9's transformation, RED was able to secure victory at Upward. The team celebrated their victory back at their HQ. K-9 had already turned back to his dog form and was currently sleeping. While he was doing so, the four buildings were talking about what exactly happened today.

"This doesn't make any logical sense," said Debbie. "A dog just cannot "turn" into a creature like that, who can also uber itself, and break through ubers as well,"

"Well its on the same stupidity that brought us to life," said Stella. "Besides, as long as he doesn't hurt anyone but BLUs then we're fine,"

Debbie sighed. Stella only liked to see the center of the picture, rather than the entire picture itself. She turned to Tai.

"So what do you think triggers him to- you know?" she asked.

Tai shrugged. "I dunno, I think it activates when he's in a life or death situation. Can't really ask him since he only talks when he's in that form,"

The four were silent for the next minute. The only sound came from K-9's snoring.

"That dog is something all right," said Tia. "So glad the BLU's never got him,"

"Not really, Medic is probably going to try and figure out how he ubers himself,"

"Don't worry," said Stella. "Talked to Doc earlier, he touches K-9, and he's a dead man,"

"We should get to sleep now," said Debbie. "We have work tomorrow,"

A/N: So I am stupid. When reading your reviews, I was wondering why everyone was calling K-9 a puppy. Then I only realized NOW, why you guys are. Mini-Sentries are like baby sentries so it would make sense that K-9 is a pup. When I had the idea of K-9, I wasn't thinking of making him a pup, but no worries I've found a way that fits both sides of the spectrum.

Review Question: Should the buildings have some kind of super form of some sorts? And if so who do you want to see first?

Till next time,
