Emet

Emet, also known as the Iron Giant, is a legendary robot that attacked Mary Geoise 200 years ago. It was originally created 900 years ago, around the time of the Void Century where it was a friend of Joy Boy, for a yet unknown purpose. It was inactive due to running out of energy and is kept on Egghead. After hearing the Drums of Liberation from Monkey D. Luffy, Emet powered back up, during which it guarded Vegapunk's prerecorded video being broadcasted from within itself.
It is an ally of the Straw Hat Pirates during the Egghead Arc.
==Appearance==
Emet is a robot around as tall as the Ancient Giants. It wears a horned helmet, and its face and lower body are covered by grills with vertical bars. The left horn on its helmet broke off over two hundred years ago, and remains missing.
==Personality==
Despite being a machine, Emet does appear to be fully sentient and capable of emotion. He was very friendly and loyal to Joy Boy, liking his company and intending to make him king of something. After waking up from its slumber, it apologized to Joy Boy for failing his original mission and then started looking for him out of nostalgia.
==Relationships==
===Joy Boy===
While the full relationship between Emet and Joy Boy is yet to be revealed, it seems that Emet was someone very dear to Joy Boy to the point that he would always want to protect it even after he is long gone. Joy Boy even gave Emet a knot that contained his most powerful Haki, so the robot could use it to protect itself or someone dear to it from mortal danger.
Emet in turn reciprocated this feeling, as when it awoke during the Egghead Incident, it apologized to Joy Boy for failing to make him king. In fact, when the robot heard the Drums of Liberation for the first time after many centuries, it went to look for Joy Boy because it recognized the rhythm as the sound that Joy Boy would make. Even after finding out that the rhythm no longer belonged to Joy Boy but someone else, Emet still sided with the person and fought alongside them. During its last moments before powering down, Emet was seen happily reminiscing the time that Joy Boy gave him the knot.
==Abilities and Powers==
The full extent of its abilities is currently unknown as it ran out of energy before causing damage. However, it was able to climb the Red Line and was considered to be far beyond the scientific knowledge of the time. It later served as inspiration for Vegapunk's Vegaforce-01, however, he was unable to replicate the mysterious power source of the Iron Giant. 
The "Drums of Liberation" are somehow able to power it up, although it is still unknown how exactly this happens. Its armor is extremely tough, providing it protection from explosions and high temperatures, as it was witnessed wandering through a massive fire and relentless bombardment from a Buster Call while seemingly unbothered. Despite being easily knocked away into the sea by Topman Warcury, once Emet fully recognized Luffy as Joy Boy, the robot recovered instantly and jumped out of the ocean despite its weight and size, and punched Warcury with enough force to break off one of his tusks and cause the Elder to bleed, effectively dealing damage to his tremendous hide that not even Luffy while in his Gear 5 form was able to achieve.
Luffy determined that it is supposed to move autonomously, as he could not find a place for people to pilot it from the inside. This deduction was shown to be true as Emet could move and think for itself independently. Emet has its own voice, but so far has only been shown to be understood by those who can hear the Voice of All Things.
===Weapons===
It is shown to be wielding a polearm of some sort during its attack on Mary Geoise. It apparently once had some form of weapons mounted on its arms, although the years it spent in ruins made them inoperable.
====Haki Knot====
The man known as Joy Boy once sealed a portion of his Supreme King Haki within Emet, which could be released by untying a knot somewhere on its body. Due to possessing Joy Boy's Haki, Emet was capable of releasing it in a large burst all at once. The Haki was potent enough to travel for a long distance outside of Egghead and cancel the Devil Fruit transformation powers of the Five Elders, but was considered a one-time use weapon to be utilized in dire circumstances, with Emet deciding to unleash it at the end of the Egghead Arc.
==History==
===Past===
====Before Void Century====
Emet was originally created around 900 years ago. At some point, it became acquainted with Joy Boy and became his comrade. Eventually, Joy Boy told Emet about a certain eventuality where he wouldn't be there to protect him, hence he sealed his Conqueror's Haki inside Emet's chassis as a means to protect him and the ones who Emet wants to protect should the need ever arise. This made Emet happy, knowing that a part of Joy Boy would live on inside him long after he was gone. 
====Attack on Mary Geoise====
200 years ago, Emet suddenly appeared out of nowhere and attacked Mary Geoise, but ran out of energy before causing damage. The World Government subsequently ordered a group of scientists to destroy it, but Jaygarcia Saturn secretly commanded the scientists to hide and study it instead. It eventually fell into the hands of Vegapunk.
===Final Saga===
====Egghead Arc====
Emet was accidentally discovered by Luffy, Chopper, Jinbe, and Bonney during their stay on Egghead. Luffy attempted to climb inside the robot but was unable to, determining that it was the type that moved by itself. They were then interrupted by Vegapunk, who had gotten himself stuck while warping through the giant's outer armor. The scientist then explained its history.
During Luffy's battle against Kizaru, he activated Gear 5, which led to the Drums of Liberation reaching the Iron Giant, causing its eyes to light up. When Luffy later activated his Gear 5 form again, the Drums of Liberation triggered the Iron Giant to start moving. Fully awake, Emet walked through the flames from the Buster Call and mentally apologized to Joy Boy. As the Iron Giant continued to make its way across Egghead, Marines surrounding the island attempted to bombard it. Despite the heavy bombing, the giant was undeterred, and continued on its route with little issue. York later determined that Emet was protecting the Den Den Mushi that Vegapunk was using to broadcast his world-wide message.
After hearing York's theory, the Five Elders (save for Ethanbaron V. Nusjuro), dropped all of their previous tasks and moved in on the Iron Giant. After successfully locating and surrounding it, the Elders recognized it as the very same machine that had attacked Mary Geoise 200 years prior. After hearing Vegapunk begin to make his announcement on the meaning of the letter "D.", Topman Warcury moved in and attacked the Iron Giant, resulting in the broadcast cutting out, and the machine collapsing. The giant ended up falling into the sea and sinking down to the ocean floor while wondering about Joy Boy's whereabouts. It later reacted to the Drums of Liberation caused by another of Luffy's transformations, finally identifying his position. Remembering something Joy Boy said to it earlier, Emet suddenly emerged from the sea and punched Warcury, breaking one of his tusks and stopping the Elder from smashing into the Giant Warrior Pirates' ship.
After managing to fully reemerge from the sea, Emet was finally able to speak with Luffy, whom it called Joy Boy. Luffy heard its voice through the Voice of all things and its intentions to assist, although Luffy did not understand why or that it was an ally. Emet then prepared to use one of its weapons, although this failed, due to age making them inoperable. Due to the failure, one of Emet's arms was bitten off by Shepherd Ju Peter, although it was able to remain standing, and stood in the way of the Elders.
Emet was soon struck again by Warcury and received significant damage. Apologizing to Luffy for mistaking him for Joy Boy, Emet asked the young pirate for his name. Upon hearing that Luffy was a carrier of the Will of D., Emet thanked him for letting it hear the Drums of Liberation one last time, and released a massive burst of Supreme King Haki that was sealed inside its chassis by Joy Boy ages ago. As the burst of Haki forced the Five Elders back to Mary Geoise, Emet thought of a time it spoke to Joy Boy before powering down.
