Limit Form

Limit Form is a Drive Form which appears in Kingdom Hearts II Final Mix. It uses neither of your team members, and consumes four of Sora's Drive Bars. It represents Sora's past, and is obtained along with Oathkeeper at the end of the second visit to Twilight Town, after Sora learns about Kairi's abduction. Its emblem is a silver crown.

Appearance
Limit Form changes Sora's clothes into the same colors and style of the clothes he wore in Kingdom Hearts and Kingdom Hearts: Chain of Memories. However, a red crown appears on his knees, whereas in the previous games there were none. This is the only Drive Form where Sora has no auras of light surrounding him, although whenever he enters a new area, his torso glows red for a short time and a few specks of light fall off of him. Limit Form's version of Guard uses the Kingdom Hearts animation instead of the Kingdom Hearts II one.

Mechanics
Limit Form is a unique form that mimics Sora's abilities from the original Kingdom Hearts game. In this form, Sora's Magic commands are replaced with new Limit commands, whereby special abilities from  can be accessed for a set MP cost. Since magic is disabled, Sora cannot use Cure to heal and to compensate, each hit from a Limit recovers some HP. With the exception of Sonic Blade, the Limit attacks do not have invincibility frames that can be exploited by delaying the followup attacks, as they did in Kingdom Hearts. In general, Limit Form is a more simplistic Drive Form, as Sora retains much of his normal movement and basic combo attacks, albeit with new finishers and counter-attacks. However, Limit Form has the advantage of being able to block, jump slightly higher than usual, and roll across the ground using the form's Growth Ability.

Limit Form gains a single point of experience each time a Limit is used successfully. Levelling up upgrades the form's Growth Ability, Dodge Roll for both itself and Sora's standard form. Also, level-ups reward Sora's standard form with the Auto Limit, Draw, and Lucky Lucky abilities.

Strategy
To effectively level up Limit Form, equip as many Form Boosts as possible before engaging in battle, including Oathkeeper, and repeatedly use the Sonic Blade limit, which costs the least amount of MP to use, until MP runs out. Return to a Save Point to recover MP before returning to battle. Repeat the process until the Form gauge is about to run out, then leave the world and return to refill the Drive Gauge to maximum. Continue in this way until Limit Form reaches the desired level.

As this form is exclusive to Kingdom Hearts II Final Mix, it is recommended to make use of all the additions that are exclusive to the Final Mix version to level up Limit Form, such as the Cavern of Remembrance, where there is an abundance of Heartless, and in the Treasure Room in Agrabah, where Mushroom No. 5 can be found. The latter is recommended as it has the benefit of a nearby Save Point, and can always use it to return to the World Map if Sora's Drive Gauge is low.

Because Limit Form doesn't require any party members, the Battle of the 1000 Heartless can be very effective to level up.

Another good way to level up this form is to go to the Altar of Naught if Sora has defeated Xemnas's first form. Exiting the Altar of Naught will lead to Ruin and Creation's Passage. By using Limit Form when the Nobodies, many of whom are Berserkers, appear, Limits can be used until all Nobodies in the top area leading to the Altar of Naught are defeated, or the MP gauge runs out. Entering the Altar of Naught will immediately fill up the Drive Gauge, and this can be repeated for a simple way to level up Limit Form.
