From the Kingdom Hearts wiki
Limit Form is obtained when Sora seals the Keyhole in Twilight Town. This is the only form that Sora can trigger alone, and requires 4 bars of the Drive Gauge to activate. It is a form based on Sora's old clothes, and is exclusive to Kingdom Hearts II Final Mix. It uses abilities from Kingdom Hearts and Kingdom Hearts Final Mix that didn't appear in Kingdom Hearts II, particularly his powerful Limit commands. Its special ability is Dodge Roll, a small leap forward that defends Sora from all attacks. The color scheme of Sora's clothes in this form changes to that of his original clothes from Kingdom Hearts to reflect this. In Halloween Town, it's represented by the series' stylized heart with a red and black checkered pattern. When triggered, both partners stay by Sora's side and do not disappear, making it especially useful during tough battles and the only Form that can be used when Sora is alone.
