Sora has a typical brave and heroic personality, meaning he'll willingly risk his life for people he doesn't even know. He's extremely loyal to his friends, and has shown to be extremely forgiving to Riku (even forgiving Riku for the times he's tried to kill him). He constantly "thinks positive" and is therefore highly optimistic.

Sora has shown a large amount of gullibility. For example, he fell for Mulan's (extremely poor) attempt at passing for a man. Ironically, he doesn't let his enemies fool him as easily, since he didn't fall for Xemnas's (which was much more convincing) attempt to play on Sora's sympathetic side. Despite Sora's good nature, he appears to sometimes hold grudges, since he seemed to go after Xemnas merely out of spite for him. Sora is also often quick to anger whenever he's confused.

He seems to have a crush on Kairi (which seemed to be pointed out a few times in Kingdom Hearts II when Donald, or Goofy knew that he was thinking about her such as at the end of their first visit to Port Royal. Also he draws himself giving Kairi a paopu fruit). Kairi may also harbor some feelings for Sora but this has yet to be completely confirmed in the series.

Sora appears to be a natural swordsman, most likely due to all his training against his friends on Destiny Islands. His skill with the Keyblade increased greatly over his journey, and he has become a keyblade master. Sora's skill is so great that he has even be able to go head-to-head against legendary swordsmen such as Cloud, Leon, and even Sephiroth (although in their encounter in the second game, Sephiroth seems uninjured after the battle, even though he supposedly lost and admits that Sora is "very skilled").

Sora is also well-versed in various magic spells, even more so after training with Merlin. In Kingdom Hearts II, his basic combo is much stronger and he gains the Drive Form ability after obtaining new clothes, which give him even more mastery over his strengths. However, some aspects of Sora's abilities are ambiguous because of the reaction commands in Kingdom Hearts II. The most notable of these is during one of the reaction commands he cuts through a large building, yet in both games it takes him several hits just to break a wooden barrel. Again, this is probably due to the developers making the reaction commands epic for most of them.

Sora has become very powerful over the length of the series, being able to slay over a thousand Heartless without rest but slightly tiring after, fight and defeat all but two members, which Riku defeated, of the powerful Organization XIII, all thirteen if Absent Silhouettes are counted, go toe-to-toe with exceptionally skilled Final Fantasy combatants, fight and defeat the countless Disney villians that have faced him.

However, Sora is nearly helpless without his Keyblade. Even Shadow Heartless take a huge number of hits for him to kill without it, and that's only after he had gotten stronger on all his adventures before he reached Hollow Bastion (when he first encountered them on the Destiny Islands, Sora couldn't even damage the heartless without the Keyblade). However, he is not utterly useless in real combat without it; he is still able to cast magic with no major decrease in power, Keyblade or not (as long as he knows how).
