Koby is first introduced as a cowardly chore boy on board Alvida's ship. Through fear of being smashed by her Iron Mace, whenever she asked him who was the loveliest on the sea, he would reply, "You are, Miss Alvida". Eventually, with the help of Luffy, he found the courage to pursue his dream of leaving her and becoming a Marine.

Attack Potency: Unknown, At most Small City level+ (A single kick from him caused Luffy to cough up blood. He was however quickly subdued and forfeit the fight before Luffy could hit him.) | Unknown, Likely City level (His current status should put him at least at the same level as Tashigi post-timeskip.)

Striking Strength: Unknown

Durability: Likely Small City level+ (Took a punch from Luffy at the Marineford Battle and recovered before its conclusion) | Likely City level via powerscaling (Scaling from Tashigi, and that he wasn't even phased by a massive torpedo exploding in front of him.)

Stamina: Superhuman by virtue of enduring Garp's extremely rigorous training

Range: Standard melee range

Standard Equipment: None notable

Intelligence: He is kind and was somewhat cowardly. He didn't fight any of the pirates while present at the Marineford war out of fear, and later confronted Admiral Akainu about stopping the war due to seeing the death of so many marines and pirates to be pointless as they were merely throwing their lives away at that point. He is exceptional and had a lot of drive as he grew in strength exponentially during the training he endured under Garp. He became adept with the Rokushiki technique "Soru" in a matter of months.

Weaknesses: None notable

Notable Attacks/Techniques:

Haki: There are normally two types of Haki regular people can tap into: the Kenbunshoku Haki which allows individuals to sense the presence of others, and Busoshoku Haki which allows individuals to create an invisible armor around them. There is however, a third type of Haki, Haoshoku Haki, that only a few individuals can use. Coby is not one of these people.

  • Kenbunshoku Haki (Color of Observation or Mantra): Coby has no control over this power by the end of the pre time-skip. He can sense and emphasize with the emotions and intent of the living presence around him, but can't keep it in check, which takes a toll on his mentality by some degree.

Rokushiki: A special, superhuman martial arts style used primarily by members of Cipher Pol #9. It consists of six special techniques, Kami-e, Geppou, Rankyaku, Shigan, Soru, Tekkai. So far Koby has only displayed the use of Soru.

  • Soru: By kicking the ground at least 10 times in the blink of an eye, Koby propels himself across short distances at enhanced speeds.
  • Geppou: allows the users to actually jump off the air itself, allowing them to stay in the air for much longer than usual.

Key: Pre-timeskip | Post-timeskip

    • Coby is being scaled against the same new age marines whom he so happens to have come up (story wise) alongside: Tashigi/Smoker. From portrayal...
    • This thread is derailing towards the bottom of the sea. I suggest we close this for now and have someone open a Coby stat check thread or something.
