Groundshaker

Groundshaker is a boss from Kingdom Hearts II.

Groundshaker is a mega doppelganger-like Living Bone who roams the Pride Lands after Simba triumphs over Scar's Ghosts. The ghosts all merge to form the gigantic Heartless that is easily one of the biggest Heartless Sora ever fights, comparable only to the World of Chaos. The top of the beast is very much like a lush Savannah. He is the boss of the Pride Lands on the return visit.

Atop the beast is an unnamed witch doctor Heartless who resembles a Shaman. Similar to the Shaman and the Living Bone, the witch doctor forms a symbiotic relationship with Groundshaker. When the witch doctor's double-mask rotates, Groundshaker's head would also rotate. One side uses volcanic fire attacks, while the other side uses eerie electric magic.

It is unknown whether the beast or the witch doctor is the Heartless named Groundshaker. Timon hints that the witch controls the beast. It is entirely possible that they are one in the same, as the witch doctor sometimes merges with the beast. However when it dies the Shaman is the only one seen to vanish and a heart pop out. It is easy to tell what earlier Heartless inspired Groundshaker--he has uncanny resemblance in attack style to Behemoth from Kingdom Hearts.

Strategy
The main thing to remember is that you only have to attack its eyes, as well as the shaman-like Heartless on its back. At the start of the battle a series of reaction commands will be avaliable, jumping from the AoE ground stomps from its feet. The computer is controlling your movement, not you so don;t get confused xP. Then you will eventually jump up and parray one of its stomps by pressing Triangle rapidly, when you do this it will fall and become stunned. Nows your chance to unload the most damage you can to its main head's eyes. Magic, meele, simbas limit *if you use limits*.

When he recovers you can jump on its back from the reaction command "jump" 2wice. Theres a bitching monkey here that is the hardest part of the fight. At high health you can attack any of the 2 heads to take off hp and it casts mild magic that if your within meele range you don't have to worry about. A tip for taking this down, while attacking in the air, press Square to do some cool spinney airal thingey attack and it will knock its 2 heads off and on the ground for a short duration, Happy Nuking. If it runs away then repeat to get on its back.

When it is upright again on the Groundshaker's back the Shaman can go invisible and use Fire-like attacks (or Thunder-like attacks). During this time i advise you run clockwise around the bosses back untill its visible again, then try and stun it with the air combo i just mentioned. The duration of invisibility and the intensity of magic attacks becomes more frequent as its hp drops lower. As with all boss battles heal well, for this boss never let your hp go down to less than about half of the first circle around soras portrait, it can 1 shot you on any amount of health under that. (well that was me on proud mode so maybe a little lower for newbs)

NOTE: When you fall off the back jump up the leg or the head to get back on. DON@T STAY ON THE GROUND WHEN THE MONKEYS ON ITS BACK. You will get bombarded by magic attacks and make it almost impossible to survive, let alone get back up. Repeat untill Pwnt in the face, takes a few tries though to get the monkey part right =)*Sub*

Journal Entry

The main body on the back of the creature controlled his bones, creating chaos in the savannah.

Trivia

 * It is believed that Groundshaker is the largest Heartless that Sora ever fought (excluding World of Chaos).
 * Based on the beta screen shots, many fans believed that Behemoth would appear in Kingdom Hearts II. It did, only in the Battle of 1000 Heartless, but it could not be fought. Instead, Groundshaker took Behemoth's place as a boss battle.
 * The Groundshaker seems to have been inspired by some of the costumes in the Broadway version of the Lion King.
