1) No, Ignika's personality is subordinate to Mata Nui's, so there is no fight
2) No, not directly
3) Yes, I can. There are no Matoran in 2009. Matoran exist only in the Matoran universe.
Ignika is awesome like that. He was pure ownage throughout the whole book. =P
Too bad to see him get rid of his body, hopefully Greg decides to kick Mata Nui out of Ignika and make Ignika a new body.
Well, there's two characters in the 09 universe. Mata Nui and Ignika. But since Greg counts Ignika as an object...
BTW, I really hope for another Toa Ignika set next year.
But then again, Greg revealed that because too many people were bitching that if the Toa Nuva would die, BIONICLE WOULD BE RUINED.
Also, Greg never revealed nothing about MN=MU, the leaked vid in Amazon pretty much started that theory.
