Kakamu (OU)

Biography
Kakamu was once a Ta-Matoran living on Metru Nui in the Matoran Civil War. One day, while fighting in Ga-Metru, the protodermis banks flooded and he was swept out to sea. The part of the liquid protodermis sea he was floating unconscious in somehow became energized, and he was transformed into a Toa. There were no witnesses present, so maybe we'll never know how it happened.

As part of his transformation, his battle spear was transformed into the Guardian Fire Spear and his mask was transformed into a Daran. He was washed up on Daxia, found by a local Turaga and was recruited into the Order of Mata Nui. This Turaga became his closest friend and mentor, and taught him everything he needed to know about his powers and the Matoran Universe. He went on several missions for the Order, and made some good friends, including Yntral. On one of these missions he had to go to Le-Metru to deactivate a bomb placed on a chute by the Dark Hunters. Unknown to him, the bomb was actually a Genetic Manipulator placed there by User KoN, who wanted to create a clone of Kakamu in case he was killed or mutated. After the device took a DNA sample from several layers of Kakamu's body, it "deactivated" so Kakamu gave it to the Vahki. The Vahki put it in a storage closet, but the device was secretly still running, and over time Toa Trantoshen grew from it and was born. Kakamu's clone, or son, lived his life out on Metru Nui among the friends his father would never see again.

Elsewhere, one day Kakamu's Turaga mentor went missing, and he was filled with grief, which was one of the reasons why he decided to quit the Order. He knew that if he decided to quit, the Order would send agents after him to apprehend him, so he ran. He ran far across many islands but they eventually found him. He was cornered in an empty lab that contained a pool of Boiling Energized Protodermis and Makuta essence. In that moment he made a decision to jump into the pool and transform himself into a Makuta. Emerging from the pool anew, Kakamu found himself killing the agents and fleeing from the scene to start a new life.

He joined the Brotherhood of Makuta and became their top scientist, as he impressed Makuta Blackout. He gained a Matoran assistant named Mocax from Karda Nui and took control of Nynrah after defeating its king, Koranis. After setting up his lab with the assistance of the Nynrah Ghosts, he designed the Kordaz Sabersword (which was later destroyed by Airwatcher), and two Nirak Laser-Drills (one of which was stolen by Xeno). Once, in a battle with Voporak for the Vahi, his Guardian Fire Spear was disintegrated. Later, Kakamu fought in the Brotherhood's war against Zev Raregroove and Malygos. He owned an Axalara T9 given to him by fellow Makuta Ynot, but it was destroyed in combat. Kakamu used teleportation Kanoka to visit all sorts of weird places in the BZPB Multiverse and took a Meltrox from underneath Earth's crust and kept it as a pet. He even created new types of Rahi such as the Zahgargak and the Nui-Kiru, animals which were later contracted by the Great Beings for use in their armies, which was one of the greatest honours Kakamu had ever received.

When Blackout used the Vahi Cube to reverse time, he felt its effects and made him realise that maybe he didn't like being a Makuta, and missed the part of his life when he was a noble Toa hero. Deciding to change his life again, he infected himself with Formula 223 which was supposed to turn him back into a Toa but went wrong, turning him into a Toa-Makuta, a hybrid of both. He went rogue and rebelled against the Brotherhood, confronting Blackout when he unleashed legions of Rahkshi and wraiths on the universe. Blackout used his creation, the Vahi Cube, to transport Kakamu outside the Mata Nui robot and into interdimensional space. Kakamu absorbed a massive robot there, but it exploded, destroying Kakamu's armour. Kakamu's antidermis found a way back into normal time, and he encountered a group of Sentinels. He inhabited one for a while, but later evacuated it as he found it too clunky and restrictive.

Later, Kakamu (still in his antidermis form) found an Agori named Tratus on Bara Magna, a nearby planet. Using his telepathic abilities, he attempted to make contact with the Agori, but ended up terrifying him. Suddenly, Sunstorm arrived, turned into a gas, and attacked Kakamu. After realizing that he only had an hour until his energy dissipated, he flew towards Vulcanus. There he was forced to kill a Glatorian, Tarnok, and possess his body. In this body, he began rounding up the inhabitants of Vulcanus in order to create an army to protect themselves from invading threats such as Sunstorm.

Some time later, Blackout arrived on the planet and placed a quantity of unstable hadrium in Bara Magna's core, causing it to explode. Kakamu was vaporised in the blast, but not before he managed to make an ally of Tratus, give him a Kanoka of Teleportation and some of his antidermis in a jar, and sent him on his way.

Revived
When Tratus transported himself to the Realm of Shadows per Kakamu's orders, he combined the antidermis with the Shadow energy lingering in the dimension, duplicating Kakamu's consciousness and creating a whole new cloud of antidermis for it to travel in. The Zivon told Kakamu that he had had an unknown son millennia ago, and that he should find him if he wanted to live. With that, it opened a portal to the main dimension and threw Kakamu out. After a long period of searching and possessing a multitude of bodies, Kakamu found Trantoshen and took over his body, squeezing his consciousness on top of his son's. The only side effect of doing this was that spending so long in his son's mind caused his consciousness to split in two and a duplicate be buried within his son's subconsciousness. In Trantoshen's body, he fought off some Parasitic Fluff and Genetoes, and accidentally teleported into a room filled with liquid concrete that solidified and trapped him for several years. When the room was destroyed, he escaped alive.

Turaga-Makuta
Some time after this he left Trantoshen's body in favour of a Makuta's. He invaded the Makuta's mind and crushed it before obtaining another vial of Formula 223 to gain a Toa-Makuta body similar to his old one. One day, his old enemy/inconvenience Koranis teleported him into the midst of a swarm of parasitic fluff and Kakamu was forced to give up his powers in the form of a Nova Blast to destroy the swarm. This turned him into a Turaga-Makuta. He later reunited with Trantoshen, who was the better man and forgave him for stealing his body earlier in his life. Ynot and his crew found them to request their assistance to fight Blackout, in order to stop him from conquering Atlantis. Ynot recognized Trantoshen as someone who had attacked him before just for being a Makuta, but after seeing him with Kakamu he decided to trust him.

The Turaga Kakamu explored the galaxy for a while afterwards, but realised that his mechanical parts were slowly failing. He researched a fix and found that only Borg nanoprobes could help repair the damage to his biomechanical system, so he and Trantoshen launched a high-risk mission to infiltrate a Borg Cube and capture a drone. Unfortunately, this ended with Kakamu being assimilated and Trantoshen having to flee.

Trantoshen later freed his father from Borg control by blasting all of the Borg technology off his face. They escaped in a hurry, quickly teleporting to random co-ordinates. Kakamu was separated from his son and ended up on a deserted planet filled with parasitic fluff. He could tell that his time alive was nearly up. Before all hope was lost, he was rescued by Ynot and given shelter for a while on the Ironclad. During his time here, Blackout was again up to no good in a giant robot body fashioned from the remains of Darkmount. Determined to destroy Blackout and achieve his destiny before he died, Kakamu took an energy amplifier from the ship and teleported in front of Blackout in his giant robot body. In his final moments, Kakamu shouted "I'M GOING NOVAAA!!!" and poured all of his remaining energy into the amplifier, which amplified it and shot it at Blackout's head. Blackout's head was destroyed by the energy blast, and Blackout was forced to inhabit his original body again. Dying and floating in space, Trantoshen appeared at his father's side and listened to him speak his final words: "I have completed my destiny...". With that his second body died, and his original consciousness.

Kakamu's sacrifice was not as he intended, because Makuta Blackout remains alive to this day. But he still stopped him from conquering the entire universe. For the time being.

Resurrected... again
Remember how Kakamu's consciousness was duplicated while inside Trantoshen's mind? Well, this later enabled him to be brought back into the rest of the multiverse once his consciousness had been separated from Trantoshen's by the crew of the Prophecy. They intended to resurrect him to use him against their enemies as he was known for being a great warrior. As such, they created a new body for him made of rare Biometal, and molecularly bonded his consciousness to it via an extremely painful procedure. Upon awaking from this, he found he had brief amnesia and blasted a hole in the ship, escaping by jumping out and crashing into the planet below. Because of his shock-absorbent new form, no physical damage was done and he ran around, confused. Going after him, Trantoshen found his father and helped restore some of his memories, particularly the ones before he went down evil paths.

Uterio War and the Post-War period
At the start of the Uterio War, Kakamu was requested by Klak to join the Rebel Alliance. Seeing this as an opportunity to redeem himself, he joined and fought in several of the wars on the side of good. Following the Battle of Corrantia, he was framed for treason by the ZFT, and TPK exiled him to Tatooine. There he met Boris Johnson, and learned of an entity called the Dead Mind, which terrorized the denizens of Tatooine. Kakamu was kidnapped by the Dead Mind, and discovered that it was actually Ewen, under the control of a creature called Trixalis. He defeated Ewen/Trixalis, and then was found by Trantoshen and Starscream. Starscream used Vorahk-Kah's staff to claim Kakamu's Kraata powers, and disappeared, leaving Kakamu alone with his son. They made it off the planet, and eventually got to Malchior IV. They briefly participated in the Battle of Omega Supreme, then vanished.

Family exile
Following the catastrophic scale of events of the multiverse-wide war, Kakamu decided to take his son, Trantoshen, and two assistants Muta and Mocax, to a planet far far away... within a hundred light years away from the Dark Zones at the edge of reality, even. Upon landing from orbit, Kakamu drilled a hole into the ground of the assumed-deserted planet and built a new lab a couple of miles underneath the surface.

Powers
In the different forms he's had during his life and rebirth, Kakamu has always had a different selection of powers.

Matoran
When he was created by the Kestora as a Ta-Matoran, he was only slightly resistant to fire.

Toa
When he was a Toa of Fire, he could create, control and absorb the element, as well as use the powers of any Kanohi mask he was wearing.

Makuta
After he turned himself into a Makuta he found himself able to access all 42 Kraata powers. He kept the Kanohi Daran, the mask of confusion, to wear.

Toa-Makuta
When he took Formula 223 to try and turn himself back into a Toa, it went wrong and while he gained his fire powers and his Toa form back, his antidermis was still inside his body, which still had access to the Kraata powers when freed.

Turaga-Makuta
When he gave up most of his life force to destroy a swarm of Parasitic Fluff, he turned into a Turaga-Makuta. While in this form he still had the same powers as before, but they were severely weakened. For example, he could click his fingers and create a flicker of fire similar to lighting a match, he couldn't generate much more than that. He also retained the ability to produce nova blasts, but using one killed him.

Biometal
His biometal form is ultra-shock absorbent and he can change it into any shape he wants, though because it is made of a limited amount of biometal, size is a restriction. In this form he is normally about seven feet tall and can absorb any elemental or energy-based attack used against him for future use. His body can be compared to a battery, able to store massive amounts of power to be released at a time of his choosing. However, because he can't always remember what powers he has assimilated, he can't use all of them.

Alternate Dimensions

 * In the Shattered Mirror Universe, Kakamu was created as a Makuta instead of a Matoran. He was the leader of that universe's Brotherhood of Makuta, with Ynot being his deputy, and had homicidal tendencies. He arrived in the BZPB Multiverse via the original Shattered Mirror and fought some people.
 * In the Dark Universe, Kakamu appears to have been a Toa-Makuta who absorbed several other beings to gain power. This version of Kakamu is even more bloodthirsty than his SMU counterpart, and twice as strong. He entered the multiverse via a rip in the Void created by scientists at Side 8, and went on a rampage, destroying it and killing Vorahk-Kah as he continued his bloody exploration. He ended up on a black, rocky planet, and allied with SMK to cause further chaos.
 * In the Eternal Universe, Kakamu is quite the opposite of the aforementioned versions of himself, being a noble guardian of reality and the quality of life of its inhabitants. However, in the far future he will become corrupt, and break his own rules. He is also called "Kakuma".

Quotes
Kakamu talking to Malygos just before he was warped in-between dimensions. What Kakamu said before his final natural body died.
 * "I'm not allied with Blackout anymore. In fact, I could use a little help against him."
 * "I have completed my destiny..."

Trivia

 * Kakamu has been swept out to sea, had his armour destroyed, was caught in the explosion of a planet, teleported into the middle of a Parasitic Fluff swarm, has been super-punched in the back of the head, used up all of his life energy in a Nova Blast, and still refuses to die.
