8940 Karzahni 8940 Karzahni is a BIONICLE set which includes three figures , the main one being Karzahni himself , as well as two Matoran , Sarda and Idris , and a trap . This was a Special Edition set . Background . Karzahni and his brother Artakha were among the first creations of the Great Beings , and each was given a domain to rule over . Originally , Matoran were sent to Karzahni in order to be repaired and returned to their homelands – but Karzahni never really knew how to do his job . Instead of rebuilding them to restore their efficiency , Karzahni ' s attempts severely shortened their stature and strength . Ashamed to let others see his work , he sent a number of " repaired " Matoran with weapons to compensate for their physical shortcomings , to Mount Valmai , far away from everyone . After several more failures , Karzahni became convinced he was not to blame , but the Matoran themselves . He thought they should be punished instead of being fixed , so he imprisoned the Matoran . When nobody ever returned from Karzahni , Matoran eventually stopped being sent to him . Over time , his and Artakha ' s realms passed into legend , with the myths saying that bad or lazy Matoran were sent to him not for repair , but for punishment . When Matoran enter Karzahni ' s domain , he has them abandon their old masks as a way of making them abandon their old identities , and he uses his Kanohi Olisi to show them terrible " what - ifs " , making them lose all hope . For instance , Jaller saw the devastation which would have come to pass if Takua had never become Toa Takanuva . As a result of this , Karzahni gained possession of the Kanohi Hau Jaller wore , which had once belonged to Toa Lhikan , the hero of Metru Nui . It was only later that the Toa Nuva were able to recover it , after Karzahni had left his realm . Until recently , Karzahni did not even know of Makuta , Mata Nui , the Toa or anything else of the world outside his kingdom . His first knowledge of them came from a group of Matoran from Metru Nui . At first , he didn ' t believe the tales they told , but then through his own mask power he saw that the universe would cease to be if Mata Nui died . Now that he knows what exists outside his kingdom , he aims to take control before Mata Nui wakes up ; molding his Matoran slaves into an army for just such a purpose . He has quietly followed the Metru Nui Matoran after they escaped his realm , watching as they became the Toa Inika . Along the way , he began assembling new military forces , including Zyglak and Manutri birds . However , he lost track of the Toa after entering the undersea world of the Pit , distracted as its black water mutated him . He then came across Toa Lesovikk and attacked him in order to sharpen his combat skills . Lesovikk escaped , but the hero has vowed to destroy Karzahni rather than let him threaten any Matoran again , be they those of the undersea city of Mahri Nui or the ones living in his own realm . He was joined in this quest by Sarda and Idris , two Matoran friends of his who had long ago been sent to Karzahni ' s realm before eventually ending up in Mahri Nui . Soon afterward , Karzahni overheard some a group - including two Toa and a robot - discussing the Staff of Artakha . Hating anything to do with his brother , he immediately attacked and defeated the Toa . However , the robot was being possessed by the evil Makuta , and the two titans began to fight . Although Makuta won at first and turned Karzahni ' s army of Manas against each other , Karzahni made Makuta scream in terror by giving him a vision of Mata Nui awakening and delivering his wrath . Makuta retaliated by using his telepathic powers to completely obliterate Karzahni ' s mind , possibly making him more of a threat . Sure enough , when Lesovikk and his Matoran companions Sarda and Idris arrived at Karzahni ' s hiding place at a nearby sea cave , Karzahni used his mask power to show Lesovikk a vision of a timeline that was his greatest dream : one where his fellow Toa had not died , and one that he would never want to leave . Fortunately , Karzahni ' s illusion was flawed , and Lesovikk was able to break free . Meanwhile , Sarda and Idris lured Karzahni into a trap , and the now - captured conqueror was taken into Order of Mata Nui custody by Botar . At some point , he migrated to Spherus Magna along with the other former inhabitance of the Matoran Universe . He was later found dead in the Iron Canyon . Toa Lesovikk ' s air blade was found next to his body making him a suspect towards Karzahni ' s murder . Before being mutated Karzahni had an ancient appearance , with ebon - and gold - colored bladed armor and a Kanohi Mask that was seemingly made of three or four older masks patched together . This mask is an Olisi Mask of Alternate Futures , able to make himself and others experience alternate or possible futures ; usually bad ones . As part of his mutation in the Pit , his mask has fused to his body , but he can still use its powers . He also carries a burning chain and his gauntlets crackle with energy . Shortly after he arrived in the Pit , he found one of the Barraki squid launchers and began carrying it as his own weapon .
