Rogue Fullbuster/Abilities and Powers

Swordsmanship
Rogue has no swordsmanship abilities at all, and he has never picked up a sword in his life.

Marksmanship
Rogue is somewhat decent at shooting guns, and he only uses it against people who don't have any type of resistance to bullets or people who aren't worthy of a fight.

Hand-to-Hand Combat
Rogue is extremely proficient at hand-to-hand combat due to his devil's fruit supporting that.This makes him one of the best at using hand-to-hand combat.

Physical Strength
While Rogue is relatively strong, what makes him unique is his devil's fruit, which made him capable of breaking walls without trying in certain circumstances. He relies on the hardness of his metal (see devil's fruit) to attack with brute force.

Agility
While Rogue is quite fast compared to a normal person, he still isn't very fast. As a result, he relies entirely on the durability of his metal and his own resistance, which is effective.

Endurance
Rogue can endure massive amounts of pain before losing his wits and entering Nero. After he enters Nero, Rogue will be forced to fight until his enemy is defeated or he dies, the exception being that he is sedated.

Weapons
He uses no named weapons, but he does wield a flintlock.

Kenbunshoku Haki
Most haki users are either good at Busoshoku Haki or Kenbunshoku Haki, and Rogue is better at Busoshoku Haki. His Kenbunshoku Haki is minimal, and all it does his give him a faint idea of his opponent and notify him of the placement of living beings in a close range.

Haoshoku Haki
Rogue has Haoshoku Haki.

Pre-Timeskip
Rogue is unable to use Haoshoku Haki, but Nero is often noted to have a "godly" or "demonic" presence around him, which causes some to collapse, which is associated with Rogue's Haoshoku Haki.

Post-Timeskip
Rogue has learnt to utilize his Haoshoku Haki. While he isn't nearly as capable as pirates like Monkey D. Luffy when it comes to Haki, he still learnt how to create pulses of Haoshoku Haki.
