Earthwake

Earthwake is a giant robot who is a boss in Mario & Luigi: Dream Team. He serves to guard the Nightmare Chunk holding Bedsmith and is the second boss fought in Dreamy Wakeport. His boss battle is the third giant Dreamy Luigi battle in the game.

Appearance
Earthwake appears as a humanoid robot figure made of Wakeport's various buildings, with his head being a tower with glowing windows for eyes.

History
While exploring Dreamy Wakeport to save Bedsmith, Mario and Luigi come across his Nightmare Chunk trapped inside what appears to be a tower like building. However, the Pi'illo collector Pi'illo-per appears and warns them of a 'terrible guardian' who will attack anyone who tries to remove the Nightmare Chunks nearby from their prison, and who has destroyed many past explorers who have attempted to do the same. When Mario and Luigi hit the ! blocks nearby, the building next to them is revealed to be Earthwake's head, an alarm siren goes off and the boss battle with him commences.

After the battle, Earthwake is destroyed and Bedsmith is freed. He doesn't appear for the rest of the main adventure.

Battle
In battle, Earthwake fights in a way fairly similar to the Tower of Yikk boss from Mario & Luigi: Bowser's Inside Story, in that he tries to knock Luigi into the ocean with his attacks (and in that Luigi has to do the same to defeat him). His actual attacks do work differently however.

His primary attack is to make the various parts of his body rotate around his head as a shield. Luigi has to swat the pieces away with his hammer to leave the head open to attack, otherwise the remaining parts will ram into him and cause damage.

Another attack he uses has him create a ball made out of Wakeport's buildings and roll it towards Luigi. Luigi has to counter by jumping on top of said ball and using it to ram into Earthwake via tilting the 3DS system. He'll also send out floating pieces of debris, that will then try and either ram into Luigi or heal the boss. He can also generate metal armour that stops him being knocked back. This can be destroyed with the Drill Stomp.

Finally, Earthwake can turn into a giant hammer and swing towards Luigi in either an upwards or downwards arc, which has to be either ducked under or blocked with a hammer strike. This attack isn't used until the last third of the boss battle, at least outside of Hard mode.

Earthwake X also appears in the Battle Ring, as the third opponent faced in the Giant Luigi arena. There are no major changes to his appearance or battle here.

Hard Mode Differences
In hard mode, Earthwake has a few changes in terms of attacks, like the other giant bosses in the game. He attacks Luigi in hammer form more often, sometimes as his second attack and attacks up to ten times per turn in said form instead of about five.
