Limit Form

Limit Form is a Drive Form that 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  and Kingdom Hearts: Chain of Memories, with the addition of a red crown on his knees. This is the only Drive Form in which 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 guarding motion, rather than the standard Kingdom Hearts II motion.

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 Kingdom Hearts can be accessed for a set MP cost. Since magic is disabled, Sora cannot use Cure to heal; 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. Leveling 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, Draw, and Lucky Lucky abilities.

Strategy
As Limit Form can be used without either of Sora's party members, it is especially useful in solo fights such as the Battle of the 1000 Heartless as well as the Roxas boss fight. Its Limits can deal considerable damage while also healing Sora.

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. The Battle of the 1000 Heartless can also be a very effective place to level up the form. An alternative means of leveling the form form is to go to the Altar of Naught after Sora has defeated Xemnas's first form. Exiting the Altar of Naught will lead to Ruin and Creation's Passage, and by using Limit Form when the Nobodies appear, Limits can be used until all Nobodies in the top area leading to the Altar of Naught are defeated, or Sora's MP gauge runs out. Re-entering the Altar of Naught will immediately fill up the Drive Gauge if Sora is still in Limit Form, and as such, this tactic can be repeated for a simple way to level up Limit Form. Note that this strategy doesn't work as well on Critical Mode as Sora takes more damage and IS NOT invincible during these Limit attacks. The best way to level Limit Form on Critical Mode is to return to the Treasure Room in Agrabah, where Mushroom XIII No. 5 is found. Begin the duel and return to the stairs, but don't leave the area, and start using Sonic Rave. You can get two uses of this with one MP bar, but after one use, use an Ether to fully restore the MP Gauge. At Form Level 1, 3 limit attacks is all it takes to level up to 2. This is a consistent strategy for leveling.

Another huge strategy for leveling Limit Form is waiting until the Battle of the 1000 Heartless. By relying on Limit Form in that fight, you can easily jump to form level 5 or 6 and obtain the Lucky Lucky and Dodge Roll LV2 ability.

In "Kingdom Hearts II Final Mix", there is a useful glitch. If you set an Ether to your shortcut, and then use a Limit attack (i.e, Sonic Rave) immediately after, the attack will carry out before the Ether is used, and the Ether will restore the lost MP. This is a useful strategy that quickly gets 3 limits out of one MP gauge.
