Valor Form

Valor Form (Brave Form in the Japanese version) is the first Drive Form attained in Kingdom Hearts II. This form is obtained along with Sora's new clothes at Yen Sid's Tower. Sora merges with Goofy to transform. The form turns Sora's clothes into a red and black color scheme with a fleur-de-lis on each sleeve and pant leg. In this form, Sora wields two keyblades. This form focuses on attack, and is the most offensive than any other form. Valor Form allows Sora to get in close and bash away to do heavy damage in a short amount of time, at the cost of losing the ability to cast magic.

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, and Valor Form has a very long combo.

Support
Pros
 * Good enhancement in strength and overall stats.
 * EXPs can be gained as Sora strikes enemies, thus making it the easiest Form to level-up.

Cons
 * Magic is disabled. However, this can be mitigated should Donald serves as a healer.

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 Form have the same abilities.
 * Oddly, despite that Magic can't be used, Sora still gets an MP boost.
 * Kairi transformed into Valor Form, her own Keyblade replaced by Oathkeeper and Oblivion, in her appearance in the fanmade CG movie Dead Fantasy II.
