I also want to say, I'm a big fan of King Arthur and Merlin stories and adaptions. So I absolutely LOVE your character Pathfinder!
Villian name: Night Blade
Real Name: Ty Garrel
Appearance:
Powers and/or abilities:
-Enhanced Awareness: Within human levels of possibility, but is far more aware of his surroundings than the typical human.
-Enhanced Combat: Has above a Professional's skill level in both martial arts and swordsmanship.
-Enhanced Dexterity: Has insane control of his body and his movements. Making fumbling, clumsiness almost impossible.
-Enhanced Durability: Can take punishment that would kill mortal men, can usually take the punishment of 20 men before sucumbing to the same effects.
-Enhanced Jump: Can both high and long jump and safely land extreme distances.
-Enhanced Strength: The least obvious of his powers, his strength is the same as a genetically advantaged human who specifically trained for such strength. In other words, within human levels but just at the very best of human achievement.
-Energy Attacks: Can focus raw energy into precise and/or destructive blows.
Gear:
-Enhanced Armor: Does not get the away of his agility or maneuverability but protects him from almost all kinds of bullets and explosions. Normally it takes top of the line equipment or supernatural powers to penetrate.
-Energy Infused Sword: A sword that can infuse itself with the same energy of his energy attacks, used in a way that allows it to cut through even the hardest/most durable of materials.
Bio/Reasons: Ty used to be a hero, he would protect people from every day criminals and generally keep the world safe. And for a time he was loved, but eventually as crime went down society got scared of him. They are started to question him and exactly how safe were they really with Ty walking around free? Shortly after crime spiked, with many of the criminals being people such as former officers and soldiers that Ty once worked alongside to keep the town safe. None the less he brought them in, but this was the last straw for the public opinion. They saw him as going against societies own people and as a result was outcast as a villain and wanted criminal.
Feeling betrayed, Ty held nothing back if fighting to defend himself which left a completely ruined police force and a relatively unharmed Ty. Soon after he decided to take vengeance, becoming his only judge, jury and executioner. Finding and killing anyone who he saw to be a true villain, who very quickly became just about anyone who even doubted him. Having hit a spiral of defending himself, and fufilling 'justice' against anyone who questioned he very quickly became an outright villain, not simply a hero who had the title of villain unfairly thrown at him. Upon realizing this he forsake any attempts to better the world, and then decided if the world was to reject him then he would bend the world to his benefit. Misusing anything and anyone he could for personal gain or enjoyment, in all aspects. But realizing that this would only go so long before some super hero came in and stopped him he joined the League of Evil, in order to gain some level of security/protection, and hopefully at least make friends so some people he could truly trust.
Nemesis: He's heard rumors of a organization of people who although typical humans have gotten their hands on the same tech that Ty uses. But he has yet to run into this group of people, assuming the rumors are infact true.
