Okay this following app is made because I really want to use this guy in the RP. I know I won't be able to use him though until S1 officially returns, but I want this app here just in case.
Name: SUSTIC
Timezone: EST
NPC Character of Choice: Medic
Game of Origin: Team Fortress 2
Power: The Medic like the other TF2 classes is a human being vulnerable to all things a human is (like a shot to the head can kill him, and he can even be poisoned and whatnot.) However he makes up for with his vast knowledge on human anatomy, and medicine. He knows how to treat a person's injuries, how to take care of the sick, and even perform surgery... albeit he takes too much pleasure in performing surgery on people. In fact healing people is an unintended side effect of satisfying his own morbid curiosity. So much so that the Medic began dabbling with experimenting on souls, and had even 'surgically added' 8 more human souls to his own. Though this may be the case, and even though it probably makes him someone you don't really want to mess with or visit for a checkup, he still is a very reliable ally on the battlefield if he has his special equipment. For if you are injured on the battlefield, you can be sure that he will be there to heal you with his Medi Gun.
Equipment:
Medi Gun:
Spoiler

(The Backpack the Medi Gun is attached to as seen on the Medic:)

The Medi Gun is a device designed by the Medic. It's chief purpose is healing injured allies on the battlefield, and it does this spectacularly well. The Medi Gun is capable of healing a person who lost a limb, lost some teeth, and hell even internal bleeding and other severe injuries quite quickly. The Medi Gun can literally restore a person's limb or teeth if they had lost some in combat (or outside of combat) within mere minutes. This makes the Medi Gun a very useful medical tool on the battlefield, and even off the battlefield. The Medi Gun doesn't seem to have any ammunition as it can seemingly heal a person as long as they are in range of the Medi Gun. Granted one can still kill a person being healed by the Medi Gun, as it cannot revive people, and it is possible to beat the Medi Gun's heal rate. If someone is completely blown apart then the Medic cannot heal them (for example if the head is decapitated or the brain is damaged beyond repair then he cannot heal a person.) The Medi Gun can only heal people within a range of 20 ft. Any further and the Medi Gun cannot heal someone. Meaning he has to usually stick with a person if he wants to heal them to full health.
One special ability the Medi Gun has, but can only be used by people with a special device on their heart is the ÜberCharge ability. You see his fellow allies (the other classes of TF2) have a special device attached to their (or rather to say the donated heart of a "Mega Baboon" as a person's normal heart could not stand the device.) This device allows the Medic to deploy an ÜberCharge in a desperate situation. This ÜberCharge basically makes him, and the person he is healing to be temporarily invulnerable for about 3 minutes. However the ÜberCharge can only be sustained if the Medic keeps healing the intended target. The moment the target gets out of range of the Medic, or the Medic stops healing the target then both the Medic and the target will no longer be under the effects of ÜberCharge. The only other downside to this is that one needs a special device attached to their heart in order to be ÜberCharged, and the only people with these devices are the other classes of TF2.
Syringe Gun:
Spoiler

Syringes are fired out of the weapon at a rate of ten syringes a second, at the speed of 61.88 feet per second. The syringes follow an arced trajectory, making it necessary to lead a moving target and aim upward to compensate for distance. The total range the Syringes travel before beginning to arc downward is about 18-21 ft. The Syringe Gun is capable of dealing some serious damage, even so far as killing a person if they are stuck with enough of these deadly little things. However due to its range, it makes it a close quarters weapon.
Bonesaw:
Spoiler

A basic metal saw used to cut through a person's bones, and it makes for an excellent melee weapon.
Weaknesses: The Medic like I said is human, and despite the skills in combat (and knowledge of human anatomy allowing him to know the weak-points of the human body), he still has his weaknesses. Much like other humans he can still be killed with a gunshot to the head, getting decapitated, having a literal hole blown clean through his chest destroying his heart and lungs, his body blown apart, dying to falling from high heights, and dying due to severe poisoning. The Medic cannot heal himself directly with the Medi Gun, even though the Medi Gun does heal him passively without him actually using it, the Medi Gun's passive healing on the Medic is rather slow and slim and cannot regenerate lost limbs. Meaning he would have to have someone use the Medi Gun on him if he were to say lose an arm or something.)
His Medi Gun, and Syringe Gun due have limited ranges meaning if you can separate a Medic from an ally he won't be able to heal the opponent, and will allow you to more easily take him out before he can do anything. One can easily out run the Syringe Gun if they keep strafing around the Medic, allowing one to stay out of the Syringe Gun's range and eventually get in close to the Medic. Even then the Medic can still easily be picked off by people from a distance.
In short the Medic is a reliable ally to have, but if you can separate him from his team then you can definitely lower his effectiveness. Just be careful for the Medic's Syringe Gun, and Bonesaw.
Appearance:
Spoiler

The Medic stands at about 6ft - 6ft 1.
Personality:
The Medic at first glance seems to be a rather nice and sociable guy, and he can be. He oftentimes will exchange in small talk with his patients... even when he is performing surgery on them. He can also be a bit polite at times. However the Medic is a bit... insane. He enjoys experimenting on others, and even enjoys performing surgery on people (when they are wide awake, and being kept alive by his Medi Gun on its lowest setting.) The Medic even considers his healing to be an unintended side-effect of satisfying his own morbid curiosity. He still sort of cares about people (despite him claiming to have no compassion for the sick, and lacks any respect for human dignity), for he will heal his allies with his Medi Gun if they really need it.
The Medic at times can be a bit selfish or uncaring about his patients safety. For example when he was first experimenting on the Heavy when the Heavy's torso was blow open (the Heavy was alive, there was just a hole in his chest revealing his rib-cage and organs) one of his doves Archimedes had flown into the Heavy's chest. The Medic then shooed away the dove out of the Heavy's chest, and was more worried on it being "Filthy in there!" Showing that he was more worried about his dove's hygiene, rather than patching up the Heavy as soon as possible. He still does sort of care about treating people... He just cares more about satisfying his own Morbid Curiosity on others and whatnot rather than actually healing them at times. Hell the Medic had even lost his Medical License for removing a patient's skeleton while the patient was still alive. So yeah there is a bit of a Mad Scientist within the Medic.
Another thing to note is that the Medic is quite a cunning fellow. As he had once actually managed to make a deal with the DEVIL HIMSELF into giving him an extra 50 years on Earth, as the Medic had informed the Devil that he had 'surgically added 8 more souls to his own' and that the Devil technically doesn't own the Medic's soul unless the Medic gives over a majority of his soul... or souls. This worked, much to the chargin of the Devil.
Morality: Chaotic Neutral if not borderline Chaotic Good. He may be a Mercenary (or was a Mercenary hired by RED), but he isn't exactly evil. Yes he will experiment, and gladly perform surgery on his teammates and allies when need be. But the Medic will never betray his allies just for the heck of it. Nor will he just go around killing people for no reason... Yes he may enjoy killing, but he wouldn't do it for no reason... Well maybe... So he is a bit of Chaotic Neutral, to Chaotic Good. Sometimes Chaotic Bad
Biography: Little to nothing is known about the Medic's past, except that he was raised in Stuttgart, Germany during an era when the Hippocratic oath had been downgraded to an optional Hippocratic suggestion. All is known is that he had been hired by Redmond Mann as a trained Mercenary and field medic for the other Mercenaries of RED Team who were supposed to fight and protect RED (Reliable Excavation Demolition.) During his time as a field medic for his fellow Mercenaries he had developed the Medi Gun, had developed a ÜberCharge device for his fellow mercenaries, and had even killed his fair share of BLU Team members. Life was... pretty good for the Medic during his time as a Mercenary for RED Team.
Though at some point a 3rd brother of the Mann family was revealed. Gray Mann who with his intellect, and a robotic army (and other... help) managed to take over Mann Co. The main weapon manufacturer for both RED and BLUE Team. This caused both teams to sadly split apart. The Medic needing a job, eventually joined one of the original groups of mercenaries who were now under hire (for a short time before he was killed) for Gray Mann. Though that didn't last long after RED Team, thanks to Miss Paunling and... other reasons. With that they also managed to find Saxton Hale, President of Mann Co. Of which thanks to his help RED Team managed to bring back Mann Co. to proper business.
Then other stuff happened after they stopped the original group of mercenaries and the Medic had joined back up with everyone else.
However this changed after the Horizon Incident.
When he was brought into the real world after the Horizon Incident, the Medic found himself without a job. At first the Medic tried to get his Medical License again, and almost succeeded... but lost it on his first day on the job as a surgeon at a hospital, much like the first time he lost his Medical License in his world. The Medic then without a job decided to well... travel the world to see what this real world has to offer. After all there was so much to see and do in this real world. For a while things were going decently well. He had the money to travel, but shortly after he sloooowly started to hit the deep end of his funds for traveling...
That changed when one day when he was browsing online for some jobs (after all it's easier to look for jobs online now) at a coffee shop in Paris, he found something interesting. Someone by the name of Alphys was looking for aid in research on... souls. Not the subject he's the most skilled in, but the job did show to have decent pay. Besides who else had the knowledge on how to properly experiment on a soul? No one else to the Medic's knowledge. So the pay, combined with the prospect that he'll get to mess around and do some text experiments on some souls, he accepted. Now he's on a small ship the Dr. Wily's island.
Traumas: Due to the fact that little is known about his past, I cannot really say anything about his Traumas because it does not mention any traumas. Except for probably the first time losing his medical license due to removing some guys skeleton. Even though this does not really effect him that much. Then again that might not effect him much. After all he's a guy who is willing to surgically add 8 more souls onto his own. So I don't think he'd care too much.
Notes:
This app was recently updated with some info of lore from the TF2 Comics, which are canon to the games. Also doing a big reboot of him by having him restart in Paris this time.
