Rahkshi Overlord

"Dark Shadow? Your name, merely a title. You are nothing in my eyes, nothing more than a speck of dust."

- The Rahkshi Overlord threatening Dark Shadow.

The Rahkshi Overlord was the leader of an organization of rogue Rahkshi.

Early Life
The Rahkshi Overlord was created by the Makuta, to be an experimental Rahkshi: he was able to talk, and he was intelligent. One night, he was experimenting with serums to make him bigger, when he found a serum that he thought would make him bigger. He flipped open his Kraata holder, and he injected a small dosage of it. Almost immediately, his Kraata swelled so big it cracked the shell. Then the Kraata warped, growing legs, arms, spikes, and a head that looked surprisingly like a Rahkshi head... Amazed at what had happened, he injected all of the rest of the serum into himself. He grew to such a sixe his head bashed the ceiling of the cavern. But, he could tell from the unbearable pain in his back, he was too large, and his body would collapse in on itself. So, crouching down, he quickly rustled up a device which controlled his density. Quickly, he fastened it to his back and set it to "light". Just then, a Makuta ran in. By complete accident, he shot an eyebeam out, disintegrating the Makuta, and vaporising it's Antidermis form. Once again, he was amazed at these powers. Then Makuta Chirox came in, stating that the Overlord was "far too dangerous to be kept alive". Then the Overlord fought Chirox, and, finding he could fly, flew away, leaving Chirox unconsious. He then set up an organization of obedient Rahkshi, after finding that he had all the Makuta Powers, including creating Kraata. He made sure that all of his Rahkshi were almost as intelligent as him, but disturbingly loyal to him.

Zardra Nui
He sent an intelligent Lerahk to an Order of Mata Nui base to persuade Zarerodes to give up all of the Order's secrets. After using telepathy didn't work, the Lerahk killed Zarerodes and stole the information from his dying mind.

The Base around Zardra Nui
Sometime after that, the Toa Heroes managed to get into the base. After watching them kill R-Turahk using his Overlord Staff, he became enraged and sent several Rahkshi to attack them. When the Rahkshi failed, he turned to his second-in-command, R-Lerahk, whilst muttering about how his Rahkshi were not powerful enough. He then told R-Lerahk to fetch R-Gurahk and "prepare". When the Toa Heroes arrived in his control room he smashed into three of them, instantly winding them, and sending them crashing into the wall. Then the Order of Mata Nui members that were assigned to Zardra Nui teleported in. Then the Order of Mata Nui members and the Toa Heroes destroyed R-Lerahk, but R-Gurahk teleported away. Angered, he told them that they were too late, and that he was going to become the most powerful being in the universe. When he pulled the Kanohi Ignika out of a chest, Heldar gasped, saying that that in it's timeline, the Ignika was never taken from the bottom of the Karda Nui swamp, and that he was altering history. After Heldar revealed she was a Toa of Time, Dark Shadow teleported in as well. Quickly, the Overlord put all the Order of Mata Nui members (and the Toa Heroes)into a permanent stasis bubble. Then, after saying to Dark Shadow he was much stronger than he was, he engaged Dark Shadow in combat. After utterly destroying Dark Shadow, he popped the stasis bubble, and put the Ignika on his back. It strengthened his abilities, making him glow orange, and made him able to levitate. After reducing The High Turaga to rubble, as he was about to kill Heldar, Saveour jumped on his back, and pulled the Ignika off, pulling off parts of the Overlord in the process. Screaming in pain, the Overlord threw Saveor off. Saveor hit the wall and slid down, dazed. Just as the Overlord was about to obliterate Saveor, he noticed his density controller had been pulled off too. He reached down to clamp it back on, but too late. His body groaned and fell apat under his own weight, smashing his Overlord Staff in the process. Later, as the Toa Heroes and Order of Mata Nui members left (including The High Turaga, who had been resurrected), his eyes glowed. This could have been the last reserves of energy dwindling away, or it could have been a sign that he was still alive.
