Silver Sword Saga supervillain ideas

Premise
A man from the Savage Age (Some 15,000 years ago) who gained complete immortality and godly favor after slaying Yurlungur. While not necessarily a supervillain in the sense that he doesn't harm innocents, his new goal in life is to slay Lycan (A werewolf).

Abilities

 * Weapon Master: Due to being an ancient hunter, Monster Slayer is naturally proficient in many archaic weapons. As the years piled on he studied countless weapons but refuses to touch modern weapons such as firearms and bombs. Not only does he find them crass and "to loud", but he feels like it takes away the thrill of the hunt.
 * Extreme Agility: While not super fast, Slayer has superhuman agility and reflexes. His acrobatic skills and ability to dodge just about anything makes him capable of standing side-by-side heavy hitting supervillains and fight superheroes as a relative equal.
 * Sense of logic and patience; Setting himself aside from other villains was his calm, patient and brave personality. He never coward away in sense of great strength, but realized when he wasn't capable of fighting certain heroes and retreated. Likewise, he's very patient and tactical, planning out each "hunt" by planning his routes across his battleground and routes to escape if need be.

Powers

 * Perpetually growing strength: As described by Tawsicara, his immortality not only put him in perpetual prime, but a prime that kept growing superior to itself (compare the strength of a 15 year old in comparison to a 25 year old, then use that same level of growth over the course of thousands of years)
 * Godly favor: After slaying Yurlungur, he was gifted favor and guidance by Tawiscara. While Tawiscara doesn't aid him in battle, if he senses his favorite pawn is out of comminsion, he will help him.
 * Weather Altercation: A power gifted to him by Tawiscara, he has the ability to manipulate the weather by his emotions alone.

Weaknesses

 * Honor: Slayer isn't a coldblooded killer, he gives every hero, villain or monster he fights a fighting chance. If they're in no condition to fight on equal terms at the start of the round, then he'll let them be to fight another day. Likewise, he doesn't view his opponents as enemies, rather as equals in a game he plays.
