Okay I will finally make this guys app.
Name: Mega134
Timezone: EST.
NPC Character of Choice: Sparda AKA The Legendary Dark Knight Sparda.
Game of Origin: Well this is tricky as he himself never actually appears directly in the games, but his story is mentioned. So basically the first game, but canonically Devil May Cry 3 since DMC3 is the first game plot wise in the series.
Power: The exact extent of Sparda's powers remains unknown; but it is shown that his powers surpassed even the "Prince of Darkness" (Mundus) himself, evidenced when Sparda single-handedly defeated Mundus and his demonic armies. Though it is to be seen that his powers stem from a heat related aspect, the exact nature of his powers are uncertain as his true form appears to be partly corporeal-scales and flesh-and partly ghostly-as if made from smoke or shadow. As in Dante the abilities and utilization of fire and electricity seem to be among his abilities. Arkham himself likened obtaining Sparda's power to becoming a god. In Devil May Cry 3, Dante was unable to defeat Arkham, who wielded the Sparda sword (and thus Sparda's powers) at the time, until Vergil shows up. However, it should be noted that Griffon in the first Devil May Cry stated, after being defeated for the final time, that "[Dante's] are definitely the powers of Sparda. No, even more so.". Also, Nero was able to defeat Sanctus, who wielded Sparda and was connected to the powers of The Savior. It is suggested in Devil May Cry 4 that Sparda acquired the true extent of his power by embracing humanity, which would explain why the demons who attempt to augment their own power with Sparda's are unable to defeat the Sons of Sparda. He was also implied to be a powerful master swordsman, as he trained Baul and Modeus into powerful swordsmen and Modeus stated that Sparda was "the best swordsman in the Demon World", although Dante went so far as to mock his father's swordwork when he faced Baul.
He has all the abilities of Dante in Vergil, the healing factor, strength, the speed, the reflexes, he has all of them. However what's different is his levels of demonic power which are far greater than the Sons of Sparda Dante and Vergil. Sparda's demonic power is so great that he had been able to seal Mundus, and his entire army away SINGLE-HANDEDLY. However all of his demonic power (Minus his natural abilities like the healing factor, strength, speed, and reflexes) is in the Force Edge meaning he only has his natural demonic abilities. Meaning in order to truly reach his true power he must obtain his Force Edge once more.
Weapons: He is the wielder of the Sword of Sparda AKA The Force Edge. The Force Edge though is currently in Dante's possession, and is in Dante's shop. Meaning he is restricted currently only to his natural demon abilities, and his two guns Luce & Ombra. The Force Edge: A two handed blade that contains all of Sparda's powers as Sparda transferred his power into the sword in order to seal away Mundus, and seal the gate to the demon realm.

Currently he is without it, as it's in Dante's shop. Meaning he lacks all of his demonic power, save for his natural demonic abilities of endurance, strength, and speed.
Luce & Ombra: His two guns that he was said to have made himself.

Specs:
Spoiler
The guns are primarily modeled after the Colt M1911 design, and are quite similar to the Ebony & Ivory, but with fewer customizations.
Both weapons use customized slides and extended frames that lend them a very angular appearance.
Both weapons have been modified with short-pull triggers, target sights, beavertail grip safeties, and slam-pads on their magazines. Also, both have an additional decock lever mounted on the slide (similar to the Polish Vis).
As with Ebony & Ivory, the left-handed weapon (Ombra) uses a custom slide. The extractor and ejection port have been reversed, thus causing the spent shells to be expelled away from the shooter when used left-handed.
"Luce & Ombra" is engraved in cursive on the outward sides of both pistols, next to the image of a smiling half-moon/half-sun face.
Both handguns are outfitted with ergonomic wood grips. In the middle of the grip panels are portraits of Victorian women, just as on the Ebony & Ivory; as befits their names, Ombra's is dark-haired, and Luce's is fair-haired. Oddly enough, an engraving addressed to Dante is also carved into both sets of guns.Weaknesses: Sparda currently is without his full demonic power since all his power is stored in the Force Edge, and he currently is without it. He still possesses his natural demonic abilities such as his healing factor, superhuman stamina, speed, strength, and reflexes. He is just without his demonic power.
Being attacked by weapons with Holy properties deals more damage than normal, and even though he has a high pain tolerance attacks from these weapons can kill him if he is either attacked faster than he can heal or is attacked with enough force would cause significant damage and would take a bit longer to heal.
Use weapons that would normally be strong against demons such as demonic/holy weapons, and light/dark magic as wounds from those kind of weapons take slightly longer to heal and do significantly more damage to him.
Appearance:
His true form:

Personality: Although not much is known about him on a personal level, it is said that he was both rebellious like Dante and level-headed like Vergil. He was well revered and respected by many demons for his heroism while in service to Mundus, describing him as a 'hero among heroes'. Legends speak fondly of his courage, righteousness and his thankless missions to protect the human world at the expense of being labelled as a traitor by all of his demon brethren. Sparda's wife, Eva, always described him as being a noble fighter with courage and a righteous heart.
Sparda understood honor and possessed great wisdom. Sparda had two apprentices, Baul & Modeus, though he only entrusted his true strength and power to Modeus as opposed to his colder brother Baul. Not long before his rebellion, he swore an oath with his students to live true to their aspirations.
Morality: Noble Good. He lives to protect humanity, and more importantly those close to him.
Biography: Sparda was once one of Mundus's loyal generals. During his time in service, he was the mentor of the twin brothers Baul & Modeus, and he entrusted his teachings to Modeus. At some point he saw the tyranny and injustice of his master and rebelled, fighting to save humanity. Before his rebellion, he made a pact with his students to live true to their aspirations and to carry them out. Sparda was once one of Mundus's loyal generals.

At some point he saw the tyranny and injustice of his master and rebelled, fighting to save humanity. Before his rebellion, he made a pact with his students to live true to their aspirations and to carry them out. and what was left of Mundus's armies retreated back into the demon world. In order to close the gateway, Sparda used his own blood, along with the blood of a human priestess, in conjunction with his sword and a mystical amulet. He poured his demonic energy into his beloved sword to close the door between realms, the Temen-ni-gru, though this also robbed him of the lion's share of his abilities. As an added measure, he also imprisoned within the tower its gatekeepers, Cerberus, Agni & Rudra, Nevan, Beowulf and Leviathan, and took the names of the Seven Sins in order to imprison them and set them as seals keeping the Temen-ni-gru underground. In Devil May Cry 4 it is revealed that he sealed another path to hell in Fortuna using the Yamato. Sparda's activities over the next two thousand years are shrouded in legend, though it is understood that for a time after defeating Mundus, he ruled over the humans before eventually vanishing. Sparda later appeared in the twentieth century where he met and fell in love with a human woman named Eva, who bore him two sons... Dante and Vergil.
However all was not well as Sparda had mysteriously disappeared one day, and demons that were looking to kill Sparda (and his children.) Sparda was not around to protect them. As such Eva sacrificed her life to protect Dante and Vergil.
He is currently in the real world without his sword the Force Edge, and as such does not possess his full power. He is currently in Washington D.C. where he had been for the past few years. He is sensing Mundus's power, and as such is searching for his sword the Force Edge. One problem the power in his sword (his power) is currently asleep again due to the fact that it hasn't been used in a long time. So even when Sparda finds his sword, he still requires the power of Dante and Vergil's amulets to re-awaken the sword and in turn seal Mundus away again. Even if it means sacrificing his own life. Luckily for him... his son Dante is in the Real world... all the way in China, and Mundus's power is still weak.
Traumas: None to really mention, except for when he worked with Mundus. After seeing Mundus's tyranny Sparda had regretted ever working for him. He will do anything in his power to stop Mundus (hopefully once and for all.)
