From the Kingdom Hearts wiki
Final Form, as its name suggests, is the last Form that Sora can obtain in the game. It is obtained randomly after Sora fights Roxas in The World That Never Was; while the first occurrence of the form is random, it can be accessed at any time afterwards. It also requires 5 bars of the Drive Gauge to activate. Sora again wields two Keyblades, both through telekinesis as they float crossed behind his back. It is equally strong in both strength and magic, and is considered the most powerful among all the Drive Forms. Its special ability is Glide, which allows Sora to "ride the wind" and fly briefly. Sora wears silver clothes with white wisps adorned. In Halloween Town, it's represented by a gold-colored stylized crown. It is based on Roxas's fighting style (Final Mix) and Sora's combat when he temporarily steals Roxas' Keyblades during their fight, and uses both characters.
Since in the wiki picture, Sora has the Oathkeeper and Oblivion, I gave Sage 2 original keyblades known as "Remembered Yin" and "Forgotten Yang" referring to the Yin Yang symbol
