Dimension Link

The Dimension Link is a new feature that will be available in the upcoming Kingdom Hearts Birth by Sleep. Its name connects to its purpose as a link to summon characters from other worlds.

To use the D-Link system, you must add the it as an attack into your customized deck of attacks and can only use it when your D-Link (or Dimension Link) gauge is full. The D-Link gauge is blue and next to the HP meter. The gauge is also used in Mode Changes. You fill up your D-Link gauge by obtaining dropped blue prizes from enemies like obtaining Drive Orbs to fill your Drive Gauge in Kingdom Hearts II.

Once you have summoned a character, it changes the Command Menu gauge that is also used for Mode Changes to show how long your companion stays on the field and the face of the companion you’ve linked to will show up on the bottom right of the screen. By linking to them you will get more powerful, and be able to use unique Finish moves which have two different power up levels which they perform after gaining certain symbols next to their character image on the right of the screen.

So far, it has been said that the TGS trailer has shown Ventus with Experiment 626, Terra and Ven with Cinderella, and Aqua with Mickey in his uniform from The Sorcerer's Apprentice.

Experiment 626

 * 1 Symbol: Laser Gun
 * 2 Symbols: Spaceship

When you have 0 -1 Symbols, you can activate “Reflect Beam”. If you press the button that appears on the screen at the right time, a beam that can reflect objects will appear. When you have 2 Symbols you can activate “Ohana Beam”. Buttons will go from right to left, and if you’ve hit them all a sound wave will come from the a ukulele and attack your enemies. It seems you can use both at the same time. The Commands you can use are mostly Thunder-types. “Thunder Blitz”, “Stun Blade”, and “Esuna” are the first ones you get. Also, there are effects when you are in D-LINK, with 1 Symbol giving you an “Attack Up”, and 2 Symbols giving you “CP x 2”.

Cinderella

 * 1 Symbol: Tiara
 * 2 Symbols: Glass Slippers

When you have 0-1 Symbols you can activate “Dream Sparkle”. Raise enemies up into the sky by a magic light. At 2 Symbols you can activate “Dream Waltz”, where you will spin making a magic vortex. With either one, when you’re suppose to start the Finish move, the Carriage will appear. Pressing the button at the right time is important.
