Lhii

Lhii was a fictional Ta-Matoran that Vakama told stories of, as a Turaga while in Mata Nui. In these stories he used Lhii as a way of indirectly keeping memories of his mentor Lhikan alive. In the stories he was a legendary lava surfer said to be in the clan of Jaller, and died while surfing.

Not just through his adventures Lhii's character, was very similar to Lhikan in many ways. For one thing, their names are very similar. Plus, they were both good at lava surfing, which hints at Lhikan's expert ablity to not just surf on lava, but on other surfaces as well. Finally, Lhii is said to be in the "clan of Jaller", which hints of Lhikan's original mask being passed on to Jaller.
