Name: Karada (Japanese for “Body”)
Appearance: Natsu's Karada is somewhat unique in that there is only a slight physical change. His iris will glow with a faint blue light, this is because his blood will be mixed with his Reiatsu, giving it a strong blue glow. This also serves as to confuse those he fights, since it is so hard to notice, catching most fighters off guard.
Ability: The Reiatsu pumping through his body will increase his strength, speed and stamina, effectively making him a powerful fighter. It also grants him much better focus, and better reaction time. On top of that, he is able to make his Reiatsu to flow more towards certain parts of his body to perform higher jumps, run faster and hit harder.
Techniques:
Chikara (Japanese for “Power”)
Natsu will make his Reiatsu flow in a way that manipulates his muscles, making his body much harder and increasing his strength. He is able to reduce damage from any physical attack, and attack with great power. Power equals about the average of a Captain. Cannot be used at the same time as Chisoku. (Charge: 0 posts, 1 if any other ability has just been used. Duration: Up to 5 posts. Cooldown: 1-5 posts, depending on how long it's been active, after being turned off)
Chisoku (Japanese for “Speed”)
Focusing his Reiatsu to his legs, feet, and eyes, Natsu gains incredible speed. He also gains the focus needed to navigate at that high velocity, allowing him to react to most attacks. While the speed DOES also effectively grant his attacks impact, the attacks are far from as strong as when he uses Chikara. Speed about the same as the Shunpo of an average Captain. Cannot be used at the same time as Chikara. (Charge: 0 posts, 1 if any other ability has just been used. Duration: Up to 5 posts. Cooldown: 1-5 posts, depending on how long it's been active, after being turned off)
Ultimate Technique:
Akuma Kōtei (Japanese for Demon Emperor”)
Combining Chikara and Chisoku, this is Natsu's final technique. As for the name, Natsu says that “Power and Speed together gives birth to the Demon Emperor” – a fitting name as he only uses this when he truly intends to hurt his enemy, or is fighting an enemy of the highest class. He is able to deliver blows that, aside from the added strength of Chikara also carries the impact granted by Chisoku. (Charge: 1 post, both Chikara and Chisoku must not be on cooldown, nor can they be active. Duration: 4 posts. Can only be used once per battle, 3 times per day)
Yes, the Ultimate is basically just using the other 2 techniques at the same time. Decided to go with Japanese names since my character is Japanese/English.
