League of Legends: The Others.

Not far from the team representing Demacia sat the other team, the one fighting for Noxus. And Zaun, to be frank. This team, unlike the other one, knew each other since earlier, and they spent the time pre-fight talking to each other and planning strategies. Clearly they hadn't met Jax and his thoughts on what to do before a fight. Worth noting was that this team was a lot more… Weird. The Noxian team had moved all sofas and furniture to a ring in the middle of the room, and it sure was a sight to see: The red-haired assassin called Katarina sat to the further left, looking extremely uncomfortable every time the hulking monstrosity known as Dr. Mundo moved or made a sound. Which he did, a lot. Next to Mundo sat Warwick, probably the best known in the team: He was a big, gray werewolf, clad in armor.
"So" he snarled, "we're just gonna do this as we usually do?" Mundo nodded enthusiastically.
"Mundo go and kill tiny men, because…"
"You go where you please, we know." It was Singed, Warwick's former apprentice and now a crazy alchemy-master, he too clad in armor. Mundo nodded again.
"Mundo goes where he pleases" he said, and looked at his rusty cleaver, lying at his feet. Katarina finally managed to get out of the sofa, and she brushed her clothes off and looked at her teammates.
"You guys underestimate the other team. I think Demacia is tired of losing land to us, so they will probably send in the best they have this time. THE BEST." The final member of the team, the crazy jester known as Shaco, got up and stared at her.
"I think it's YOU who are underestimating US. You know full well how good we are, since you've fought with us countless times, so you shouldn't worry." Katarina was shaken out of her resolve, since Shaco, though eloquent and sure-sounding, stared at her with a look that only spelled out insanity and murder. The clown paint sure didn't help out either. Shaco ignored her and pulled his two daggers and started to juggle them in the air.
"First" he said, "we kill them." His juggling tempo increased.
"Then, we make them fear us." He quickly threw one of the daggers into the face of a painting on the wall.
"Then" he laughed, "we win." He threw the other one, and the painting split in two. Warwick snorted.
"You sure can talk, jester, but can we trust in you on the battlefield? You know as well as anyone that you are one of the few champions that NO ONE trusts. Not Noxus, not Demacia, no one." Shaco quickly turned to face the werewolf.
"Just don't run off into the woods when we need you, doggy, and I'll fulfill my quota of champion-blood spilt." Warwick growled and bared his fangs, but Mundo got out of his seat.
"Mundo thinks clown talks too much. Mundo thinks clown should shut his face until the match starts." Shaco, unfazed by everything, glared at Mundo. "Or whaaaat?"
"Or Mundo will sharpen his cleaver on your ribs, tiny man." Mundo finished his statement with a grotesque slurping noise, and no one dared to make a witty comeback. There was a reason why Mundo was on the team; he was very good at killing people. Singed too rose from his seat.
"Let's not make more enemies than the five Demacians that we'll face on the field of battle, shall we? I still think that there is some sense in what Katarina says; the Demacians must be getting frustrated after three grand losses in a row. This is land and riches we are fighting for, you know." He stroke his bony chin.
"However, I find worrying to be foolish right now. We don't even know who we're up against, and maybe we are just over-thinking this thing about Demacia sending in some kind of elite champions against us. I say 'wait and see'." Warwick made a hacking, breathy noise that people assumed was his way of laughing.
"Sounds good to me" he said, and the other champions nodded in unison. A door in the right end of the room suddenly flew open, and an ominous sound came from within. Shaco's grin became even wider.
"Looks like it's time" he snickered. Mundo slurped even more than usual, and he picked up his trusty cleaver, swung it a few times and laughed.
"Now, Mundo goes to battle against tiny enemies." Singed patted the purple behemoth on his massive shoulder.
"Don't get cocky, Mundo. I hear there's a Demacian out there that's even bigger than you." Mundo looked at Singed, and snorted.
"Then people are lying to tiny Singed." The entire team stepped through the door and onto the platform that was located inside. They all felt that strange feeling, like something tugged at their souls, and suddenly, they stood on a fountain-like hill, with a view of a huge, green forest, dotted with blue and purple towers. The team noticed a flash of light on the far end of the forest, and they knew that the Demacian team had just arrived. Warwick howled loudly.
"Let's make this fun."
