From the Kingdom Hearts wiki
Sora gains this form when he obtains his new clothes from the fairies at Yen Sid's Tower (making it the first Drive Form he ever obtains), and requires 3 bars of the Drive Gauge to activate. Valor Form allows Sora to wield two Keyblades of the player's choosing at the same time, with red electricity flowing through them. It specializes in physical combat, having extended, faster combos, but is unable to cast spells or use any kind of MP-consuming ability, contrasting Wisdom Form. It is useful for quickly dealing a lot of damage or hits from attacking, but is the weakest Form in terms of defense, owing to Sora's inability to Guard or use Magic. Its special ability is the High Jump, which heightens Sora's normal jump, and can also be obtained for normal Sora at higher levels. Sora wears red clothes with a red fleur-de-lis symbol.
Also fun fact, since the picture in the wiki has Sora with the Kingdom Key and the Oathkeeper, I decide to have Sage use her base keyblade/the green one known as "Natures voice" and the Oblivion/the black one
