Gigas Shadow

The Gigant Shadow (ギガントシャドウ) is a giant version of the Shadow, encountered at Wonderland in Kingdom Hearts Final Mix. It only appears after defeating many waves of Shadows in the Bizarre Room. They may look big but they're actually normal size compared to the normal-sized Sora.

If a Giant Shadow manages to strike Sora, it will escape the fight, reducing the odds of winning a rare Synthesis material.

Kingdom Hearts Final Mix

 * Wonderland

Kingdom Hearts 358/2 Days

 * Beast's Castle

Strategy
Gigant Shadows attack the same way normal shadows do with the exception that they do not become flat and move along floors. Being large and having much more HP than other heartless in the area. they can quickly surround and swipe at Sora. This can be avoided by moving into a corner on an elevated surface where the only a few Giant Shadows can attack at once.
