As soon as the conversation between Young Xehanort and Young Eraqus ends, we see Sora climb over a ledge to continue forward. With a quick eye, you can see some sparkles right before Sora reaches the ledge. We can assume that this means Sora can't regularly jump over it, so he has to use a certain ability to get over it.
After encountering the new water-type Heartless in this world, we see Sora casting multiple Fire spells on the enemies and casting a large Fire spell after doing an air-combo. The Fire was most likely used as a Finisher.
With the battle between the flying Heartless enemies, Fire was used off-screen, so we can assume that it was Donald who used it.
When Sora and the group encounter the new Gladiator-type Heartless, it appears that Sora, Donald, and Goofy are using a Trinity version of the Goofy Charge, and they use it against the Heartless.
In the next scene, we see Sora running up a wall and heading toward the Rock Titan with rocks falling toward him. Sora is using the new ability called "free run".
Once Sora reaches the top of the cliff, Sora moves from the feet of the Rock Titan to the head area.
After an attack on the foot of the Titan, Sora summons the Big Magic Mountain attraction that we saw in the
After Sora and the gang reach the Tangled world, with Sora donning his new clothes, they're faced against dandelion-like Heartless, and Sora uses an Aero spell as an offensive attack.
Soon after that, Sora uses a Keyblade Transformation and transforms his new Keyblade, which looks like the Keyblade many people saw at the Kingdom Hearts HD 2.5 ReMIX launch party, into the Two Shot Blaster, and then into a large cannon.
The next scene shows Sora once again using Aero spells, but moving at the same time.
Next, we see Sora summoning the Pirate Ship and defeating the Heartless in the world.
In Twilight Town, Sora uses Blizzard and slides on the trail it left, into a Blizzard jump-pad, and Sora comes down using the Two Shot Blaster and, we're assuming, Blizzard.
In the same scene, Sora bounces off the wall, where the covered up hole is, and attacks the Big Body similarly to how Sora attacks in Dream Drop Distance with Flowmotion.
Still in Twilight Town, Sora summons three giant Teacups, similar to the Mad Tea Party ride in the Magic Kingdom theme park, and Sora, Donald, and Goofy are inside of them spinning until they come together to use a Finish.
Lastly, Sora transforms his Keyblade, that seems to be obtained from the Hercules world, from a giant sword, to a shield, to chariot with Pegasus leading it while lightning strikes the enemies.
