So... does this mean there might be two Jallers? One in the MU and one in the Red Star?
The Red Star really makes Bionicle canon... interesting. I so wish Farshtey would have gotten the chance to finish the serials. A Hydraxon on Hydraxon fight is super interesting. Lots of cool implications and discussions to be had on the nature of individuality.
Though that sort of breaks apart for me with Jaller since he's a pretty straight laced character and wouldn't fight with a copy of himself if he can help it... unless they're a zombie. It really would help discussions like these to have gotten some conclusions. I don't fully remember how the Red Star handles resurrection, as in if it only needs the body or if the character can be revived just with their spirit (which is so, so nebulous).
Also,I don't know exactly how closely we should follow the movies as a source of canon since at the end of MoL it's sort of implied that Mata-Nui is awakened (I think, it has been a long time). I'm guessing this is cause Bionicle was meant to end in 2003?
Still, it would be pretty dope to see Jaller playing with his old corpse like a puppet. Could start a funny comedy routine, his ex-corpse serving as a dummy. Pull some funny pranks on Hahli. Oh, the possibilities.
