Going to play as myself. Hopefully I'm original enough. :I
Name: Keldeo
Gender: Stallion
Age: 19
Profession:Pony of the law! As a pony of the law, he is respected by officers above him for being enthusiastic and determined. However, peer police ponies generally tend to see him as taking his job too seriously. He's often been shunned by them and sometimes treated badly.
He's also a part-time critic of fan fiction novels, though that fact is not known by many.
Cutie mark/Appearance/size/Pictures: Keldeo has no cutie mark. He does not have the means of obtaining one. As a result, he's often made fun of by ponies, which makes it all the more hard for him to fit in the society of ponies.
(You can use my avatar or pictures of Keldeo on google for reference on Keldeo's appearance). Keldeo looks very different from the normal unicorn, and is often made fun of for his looks by some ponies. Keldeo hates it when he is made fun of, though he has gotten used to it somewhat. However, not everypony thinks he looks strange.
Keldeo is rather short surprisingly. He is about the size of a mare, though his hair makes him look taller somewhat. He generally looks to be of average height to most onlookers.
Deepest and most Personal Fears [Important](<- not creepy at all):
He hates and has a fear of heights, and distastes the cold. Keldeo thinks himself to be fearless, however, there are many things he fears, though most are hidden back in the depths of his mind.
Keldeo's personal goal is to prevent those he cares about from suffering. Unfortunately, he hasn't found many ponies to care about in Equestria. However, Keldeo will do anything to prevent harm to come to the Swords of Justice or those he knows back home in his world.
Keldeo, unknown to himself currently, also has a fear of mares. He also is terrified of getting married. Why? Because he has never dealt with woman in his life. (Virizion, though she is a girl, was too tomboyish for Keldeo to have noticed any girl traits. Why? Because she's lived around a bunch of crime-fighting, adrenaline-fueled shenanigans all her life.)
Race: Unicorn. However, as a unicorn, he struggles with magic and is most often unable to wield it.
Fun fact, he uses his horn as a sword. However, after being laughed at because of it he generally only does it when really needed or when nopony else is watching.
Personality:Keldeo has always wanted to be the best in everything he does, exactly what has been the question ever since he has been in Equestria however. He is, or at least was, a student, and was put under rigorous training to become a Sword of Justice. After leaving to Equestria, this training followed him, but the young and brash side of him stayed. He is a pony of action, and generally responds quickly to some incidents. Sometimes this can be a little bad for him since he is quick to conclusions and to judge. However, he generally doesn't mean to sound rude, and does so sometimes unintentionally.
Even though Keldeo has trained as a Sword of Justice and to uphold his own personal goal, in Equestria he's very often outsped, outsmarted, and sometimes even overpowered by others. Though Keldeo does have one asset, he is determined. He won't give up; though he admits defeat when the time is truly right.
Keldeo does quite often start arguments. He responds harshly whenever somepony makes fun of him or says something aggressively to him. When arguing, sometimes he tried to reply with sarcasm and wit, though it does not usually get him far.
Keldeo wants to be a do-good hero to everypony, however, due to his appearance and young, brash behavior, he'll sometimes just end up causing an argument rather than helping everypony.
Once you get to know Keldeo, he's very open and kind. Behind his usual pride and determination is a humorous, enthusiastic, loyal, and fun-loving nature. Keldeo will open up and become very talkative to those he befriends. He likes to talk a lot about his interests such as sword fighting. He'll even share his stories as a Sword of Justice, though he'll often exaggerate them. When other ponies are talking, he likes to show them up and make himself sound better. However, he can listen to other ponies, though sometimes he does lose interest.
When shipped, Keldeo will be extremely embarrassed. He's never that good around mares, and wouldn't be able say anything (coherent, that is) if his life depended on it. Even though he has trouble talking to mares when moments heat up, he likes to impress them. He'd probably run and hide if he were being chase by a bunch of love struck mares.
Backstory:Keldeo first came in contact with Equestria when researchers in Canterlot discovered a bridge to his world. As a result of the magic environment in Equestria interacting with his closeness in form to a unicorn, Keldeo was attracted to the portal. At first, he was able to travel freely between his world and Equestria, but an incident involving a pony traveling to Keldeo's world broke the connection leaving Keldeo stranded in Equestria.
As for Keldeo's past, his family was killed in a fire caused by a war. He never got the chance to ever know his parents that well, so he often remembers back to that day, trying to recall anything about them before they were killed. He was rescued from that same fire by the Swords of Justice, a travelling group of fighters that strongly upheld justice and fought against both sides of warring nations. ((and were able to uphold themselves at that!)) The mere fact that Keldeo was brought up by this environment made him a pony of action that upheld the law, even at the cost of self-sacrifice. Keldeo's made a personal promise that he would prevent those he cared about from being made to suffer, and has constantly trained himself to try to live up to that goal.
The separation from his world left a lasting blow on Keldeo, he had to suffer through the loss of his foster-family, and continue living with the knowledge that they thought him to be dead. At first it was hard for Keldeo to build up his new life in Equestria, ponies did not accept him well, ((you have the lack of a cutie mark to thank for that.)) However, he managed to live up to the title of being a law-enforcing pony.
That's all. I used to have a better version, but I accidentally wrote over it. Sorry if it's got a mistake or two. xD
And note, your OCs will probably die, so keep note of that.
Wait wat. I'm gonna die?!
