SPUF Runner-up: Kayohgee

Bio
Quite literally a "Baby man", the mercenary known as the Heavy in TF2niverse-159354 is the result of an experiment in which a prototype Mark IV "Manndroid" Exo-suit was given a single infant pilot (as the capsule was originally built for chimpanzees and was therefore unsuitable for an adult human).

The pilot's name, gender or (brief) personal history are a mystery, as are its motivations. While it clearly enjoys its work, whether the infant believes it is "playing" with the other mercenaries or is truly psychopathic at an impossibly young age is unknown. What is known, to allies and enemies alike, is that he or she has proven to be one of the most efficient killing machines in the Mann Co. army, and is indisputably the second deadliest baby on Earth. With a suit constructed out of solid Adamanntium and an arsenal of weapons at its disposal, the Heavy's only true weakness is its mobility. While the Mark IV is capable of travelling at speeds exceeding those of an ordinary human, its infant pilot consistently scores well below the accepted minimum on the "Ability to walk" portion of his or her yearly physical and tends to precariously stumble around the battleground, a featherweight away from toppling over.

Weapons
Primary: Dual Miniguns - one mounted to each arm.
Secondary: The BaBa - this consumable calms the Heavy, boosting his accuracy for a short time, but afterwards causes him to nap for six seconds.
Melee: The Rattle of Steel

Voice Lines
While the Heavy is only able to babble, his or her telltale gleeful laughter is often heard while mowing down entire waves of opponents.

Editor's Note: I preferred that this be a monkey to a baby, not just because shooting at babies seems wrong somehow but because it generates a little bit of diversity in character. I left it as a baby for the purposes of this posting. But seriously, who couldn't love the idea of a Monkeynaut Heavy?

SPUF Character Contest Runner Up: The Medic

 Dexter is in his mid-twenties. He's of unknown European heritage but he has become accustomed to the US. He is tall and fairly skinny, with blond hair and blue eyes. The attack from the RED Spy has left scars on his left arm and left cheek. His mercenary uniform comprises of a short-sleeved shirt, a grey tie and trousers with heavy military boots. He wears short, blue gloves and bands on his arms showing his mercenary class. Attached to Dexter's belt is an unusual machine, that creates a magnetic healing field. The machine is attached to his Medigun, which is worn on his back when he's not using it.

Dexter's weaponry consists of multiple scalpels that he wears on his belt, his Medigun, which is a heavily modified shotgun with two firing modes. The first mode fires a beam of healing plasma, controlled by a magnetic field. The second mode fires buckshot, which, when it hits a wall, releases a healing gas. Dexter also carries a revolver for when he needs to go on the defence.

Quotes:
When healing a team mate:
"Oh dear, silly you, getting yourself injured again..."
"If only friendships were this easy to fix..."
"You're all fixed up. Try not to do that again."

When killing an enemy:
"You'd think I'd be easy to kill, what with me only having a revolver..."

When injured:
"Might be a wise idea to pull back and heal up..."
"If only this device worked on me..."

When close to death:
"It's a good thing me and Dell invented the RESPAWN machine..."

Domination lines:
"Hah! You let yourself be killed by a doctor?"
"Pfft. You weren't even close!"
"Only one person got close to killing me, and you're not him... Okay, two people..."

Domination line against Spies:
"Seems like you've lost your touch!"
"C'mon! Last time we met, you nearly killed me!"

Domination line against Engineers:
"You traitor!"
"That will teach you to focus entirely on killing!"

Editor's Note: I liked the original nature of this character. It departs a bit from the very detached framework typical of TF2, creating a very specific character with a closely generated backstory. There's a bit of thought here, plus there's lots of voice lines, which I always like to see. Good work.  Check out The Medic's blog!

SPUF Character Contest 2 Winner: Stamda

The Mercenaries in TF2 are just guys. They work their jobs--blowing things up, shooting people in the head, shooting lots of people in the head, keeping people alive, shooting people in the head with rockets--but they're regular guys from a variety of backstories.

Those backstories are arbitrary, and I wanted to change them. Not because I think they're bad, but they're arbitrary and I wanted to see who else could do these jobs! So I challenged SPUF and said "Show me your moves!" Design a new version of a TF2 class, write a couple voice lines for 'em, tell me what their default melee weapons, and I promised them that I'd put them here.

Well, here's one by Stamda, who won the contest! Runners up to follow!

The Sniper
Bio: Stay off her lawn! A curmudgeonly old hag from Fort Gratiot Township, Michigan, this geriatric banshee of a woman can thread bullets through skulls as easily as she can string into sweaters! If you don't get a head full of lead, you'll sure as hell get an earful of berating from this living insult generator! She's mighty good at cribbage and checkers, too.
Appearance: Wrinkled, sunken face, gummed mouth, bifocals, an orange wig, a nightgown and slippers. Stands with a hunch, runs with a hobble and swings melee weapons meagerly.
Weapon changes:  -Rifle is an ironsights rifle with a crack in the stock and a piece of fake hair stuck in the ejection port. -SMG is dual Scorpion variants that are heavily beaten, with a tally mark (totalling 7) labeled "Husbands" on the right gun. -Melee is a rolling pin with flour and blood on it.  Voice: Raspy, wheezy, and intended to annoy.
Voiceline examples:  Kill streak: "Do they kill boys at birth now or what?" Headshot: "Here, let me help your miserable wife out!" Melee dare: "Don't run, you'll just die tired and an embarrassment!" Dominating a Scout: "Nyeeheehee, my dentures are squrrielier than you, schoolgirl!"
