Valor Form

The Valor Form (or Brave Form in the Japanese version) is the first Drive Form attained in Kingdom Hearts II. Sora merges with Goofy to transform. The form turns Sora's clothes into a red color scheme with symbols on the sleeves and pant's legs. In this form, Sora can weild two keyblades (possibly a trait passed down from Roxas actually). This form has the second highest attack boost (first being Final Form), but this form is more offensive that any other form. Excellent in most boss fights, this form allows Sora to get in close and bash away to do heavy damage in a short amount of time. A con of this form though, is that Sora cannot conduct any magic attacks. It is symbolized by a red fleur-de-lis.

How to Obtain
This form is obtained along with Sora's new clothes at Yen Sid's Tower. It is the first Drive Form to be obtained, and the best for battles as well.

Leveling Up
The Valor Form has the easiest way to level compared to the others. It levels up simply by landing successful hits on an enemy. If a hit is blocked, though, it will not count. It is best used in Boss Battles for this.

Trivia

 * If one uses a cheat device to get this Form while still playing as Roxas, they will discover that Dual-Wield Roxas and Valor Sora are the same form. This probably explains why Dual-Wield Roxas has the ability Scan even if regular Roxas doesn't (Valor Sora has the Scan ability).
 * Oddly, despite that Magic can't be used, Sora still gets an MP boost.
