Description . This set includes Tahu Nuva , the upgraded version of 8534 Tahu . Tahu carries two silver swords , which channel his power of Fire , and may be the most powerful BIONICLE weapons . Tahu can attach the swords to his feet to create a lavaboard , which he uses to ride molten magma . Of all the Toa Nuva , Tahu Nuva most welcomes his new power . Now he feels even more confident that he can protect Ta - Koro from any danger ! When trouble threatens , his magma swords can be joined together to form a lava board that carries him swiftly over the magma flows . He wears the Hau Nuva , which he uses to protect his people against any harm . Background . With the Bohrok defeated , the Toa Nuva returned home and began to repair the damage done by the Bohrok . Each Toa had received a symbol at their respective Suva upon becoming Toa Nuva . Shortly after Tahu Nuva received his , Turaga Vakama gave Tahu the Vahi , Legendary Mask of Time . At their first meeting as Toa Nuva , the Toa all got into a fight while showing off their new powers . An argument began , once again resulting in the Toa going their separate ways . Tahu returned to Ta - Koro and encountered a strange new Bohrok , the Tahnok - Kal . When the Tahnok - Kal was escaping with Tahu Nuva ' s symbol , the Toa Nuva of Fire confronted him at the gates to Ta - Koro . When he tried to access his fire powers to stop the Bohrok - Kal , he was momentarily stunned by their absence . Tahnok - Kal took advantage of the delay to collapse the gateway above him , burying Tahu in a pile of rubble . By the time Tahu extricated himself , Tahnok - Kal had left . Tahu , Takua and Jaller pursued the Tahnok - Kal , following its trail to Le - Wahi . When in Le - Wahi , Lewa Nuva literally fell in on the group . He explained that his powers had disappeared as well , and joined the three in their pursuit of the Bohrok - Kal . The search led them next to Po - Wahi , where the two Bohrok - Kal they were observing met with another . This revelation led to the discovery of Pohatu , also powerless , encased in magnetized Mahi . The two Toa Nuva freed their ally , and he joined with them in the search . Their path led them all over Mata Nui , where the rest of the Toa Nuva , their powers also stolen , joined with them . Eventually , they ran into six Bohrok - like creatures who could talk and had different powers . They called themselves Bohrok - Kal and claimed to be searching for the Bahrag . The Toa Nuva attempted to fight them , but were essentially helpless without their elemental powers . They were all rendered unconscious by a combination attack of Vacuum , Sonics , and Electricity . When they awoke , the Toa Nuva discovered that the Bohrok - Kal had krana - kal as the Bohrok had krana . They split up to get the krana - kal from the Bohrok - Kal , sure that when they are removed , the Bohrok - Kal would be rendered helpless . Tahu tried to get Pahrak - Kal ' s Krana - Kal , but he was failing horribly . So enraged was he that it appeared he would rather sacrifice himself than give in . Jaller showed up and told him that he had no right to do so , and subsequently wrenched the Krana - Kal from Pahrak - Kal ' s body . Unfortunately , a Gahlok Va quickly replaced it with a new one . Later , Tahu met up with Lewa in Le - Wahi while searching for Kanohi Nuva . Lewa decided to be his guide through the jungle , and Tahu agreed . The Toa came to a swamp where Nuhvok - Kal had been earlier , as Tahu had figured out by studying impossibly heavy trees blocking the path . Lewa formed a plan to get several Le - Matoran to jump out from all directions and surprise Nuhvok - Kal . They got the Le - Matoran ready , and Tahu lured Nuhvok - Kal over by taunting him and then swinging on vines back to the swamp . The plan worked , but Nuhvok - Kal escaped . Gali later summoned Kopaka and Tahu to meet up with her to get their last three Kanohi Nuva in the Place of Shadow . Tahu and Kopaka were arguing the whole trip despite Gali ' s attempts to calm them . After getting through several challenges , they reached the masks , out in the open . They took the masks , only for the ground to crumble underneath them , leading to a chamber far below where the other Toa Nuva and Turaga Vakama were . They encountered a huge beast known as the Rahi Nui . With Vakama ' s help , they were able to beat the beast and then combined the powers of the Miru Nuva and Kakama Nuva to fly out of the chamber . The Toa split up and began again the fight against the Bohrok - Kal . Eventually , Tahu met up with Pohatu and Onua in Le - Wahi , who had a disturbing discovery that they refused to tell until they met up with the others . Soon enough , Kopaka , Gali and Lewa arrived and told of how they had formed a Toa Kaita Nuva , Wairuha Nuva , to try to defeat Kohrak - Kal , Lehvak - Kal , and Gahlok - Kal , but they formed their own Kaita and beat Wairuha Nuva easily . Pohatu and Onua told of their discovery : they had defeated Tahnok - Kal and removed its Krana - kal , but the Krana - kal said they were too late , that the Bahrag had already been found . The Toa Nuva descended into the Bohrok nest and had Lewa levitate down first . He saw the Bohrok - Kal fighting the Exo - Toa , the Bahrag in their prison and a large floating cube with spaces to put in the Toa ' s symbols . The Toa went down into the Bahrag ' s chamber , hoping the Kanohi Nuva masks they had found would be enough . Once down there , Tahu revealed to the others how Vakama had given him the Vahi . Unfortunately , the Vahi didn ' t affect the Kal who were protected by a force field as they drew so close to the end of their mission . Then Gali had an idea — to channel their power through their symbols and into the Bohrok - Kal . The Bohrok - Kal became arrogant with their newfound power , beginning to think they would not need to awaken the Bahrag . But the power kept coming , and eventually an overload of power destroyed each Bohrok - Kal . The Toa Nuva , their elemental powers returned to them , returned to their villages and hid their symbols in more secure locations , for a period of peace and prosperity . Tahu and the other Toa Nuva were told that they were not the first Toa team . Turaga Vakama told them of Metru Nui , the Toa Metru , the Visorak , and how they rescued the Matoran . Then , as soon as they heard that Mata Nui was dying , they immediately headed for Voya Nui . But he rushed ahead and got poisoned , resulting in his team ' s capture . They were rescued by the Voya Nui Resistance Team and were told of the Toa Inika . Later , he , Takanuva , Nektann , and a Rahkshi wound up on Bara Magna , and came into contact with the Kanohi Ignika , transforming him back into a Toa Mata .
