Shake King

The Shake King is a pirate first appearing in the game Wario Land: Shake It!. The Shake King and his pirate gang, comprised of many Bandineros, attempted to take over the Shake Dimension. In order to do so, they attacked the Shake Dimension and imprisoned its ruler, Queen Merelda, and her loyal subjects (the Merfles), on their ship. The greedy pirates stole the Shake Dimension's treasure as well (known as the Bottomless Coin Sack, which could spit out an endless amount of coins every time it was shaken). However, one Merfle managed to escape from the pirate ship and got into Wario's world, to seek help in liberating the Shake Dimension from the Shake King's rule (which Wario agrees toward, but mainly for the Bottomless Coin Sack itself). If Wario collected all of the Boss icons, Wario could locate the Shake King's ship where the final confrontation awaits against the Shake King himself.

In normal levels, if the timer for reaching the exit with the saved Merfle reaches zero, the Shake King will take Wario to Shake King's Residence, then grab Wario, take all of his collected items away, and throw him back to the checkpoint or farther away from it.

Wario's Battle with the Shake King
When Wario manages to obtain five boss emblems and gains access to the Shake King's ship, the final battle is split into three parts, as follows:

Wario must jump on the Shake King when he uses his charge attack (very similar to Wario's) to make him crash into a wall. Next, he must use a charge attack on his bottom repeatedly until he falls out of the wall, stunned. After he does that, Wario should throw him into any wall, doing a large amount of damage. However, the player may choose to shake the boss before throwing him to cause damage, as this produces large amounts of coins. When the Shake King is charging any attack (other than the charge), Wario can use an Earthshake Punch to cancel the attack. If Wario does an Earthshake Punch when the Shake King does, his own punch has the possibility of countering it and granting a chance to attack.
 * Stage One

Wario should repeat the same process as stage one, except now when the Shake King uses the charge, Wario will need to jump on him two times. However, the Shake King uses a new attack where he leaps into the air and hovers side to side until directly above Wario, and then uses a powerful Ground Pound. This also cause shock waves horizontally, so Wario must dodge these as well as the initial impact. Another difference in this stage of the battle is that while the Shake King previously threw a giant Bandinero as a form of attack, he now throws a giant Bumbleprod, which must be completely avoided is it cannot be touched.
 * Stage Two

This stage takes place in Shake King's Residence in which the Shake King shook Wario in the regular stages if the player didn't make it back to the beginning before time ran out.
 * Stage Three

In order to counter the Shake King's charge, Wario will need to jump on him three times. The Shake King uses powerful magic which he did not use in the previous stages of the battle, involving many electrical attacks. In order to dodge the the thunderbolts he creates, Wario must stand in between them and move slightly to dodge the second wave which has a slightly different alignment. For the balls of electrical energy that he fires, Wario can just dodge them like a flying enemy. As for the large lightning bolts after the charge attack, he should dash under the Shake King while the lightning is temporarily stopped to charge up for a large blast. For the third blast, Wario should stand in close to avoid being shot by an energy ball.

Trivia

 * His name is an obvious pun on the word "shaking". This is fitting to what he does; shake Wario.
 * The Shake King bears a slight resemblance to Booster.
 * He resembles a Viking. It's possible that his name is a pun on that word.
 * It is interesting to note that he has the same tint of blue around the outside of his eyes like Wario. By the same token, his artwork shows him with orange eyes, but in-game, his eyes are yellow.
 * The Shake King seems to have a romantic interest in Queen Merelda, but Merelda is not interested in the Shake King. This is similar to the scenarios involving Bowser and Peach in the main Mario series installments.
 * The Shake King can use his own variation of each of Wario's standard moves. His versions are all slightly slower and have more power.
 * In the second part of the fight, the background shows a, what seems to be, incomplete replica of the Shake King and three Bandineros. This has lead some people to believe that the Shake King and the Bandinero group are robots. This is further supported by the explosion that occurred after the Shake King's defeat.
 * His shoes and general body structure resemble Wario's; However, his legs are longer.
