Let’s play a fun game.
The year is 2008. Mata Nui has just been kicked out of his body, which is now healed, conscious, and ready for Makuta Teridax’s spirit to “slip in and take his place”.
Except it doesn’t. You (being the malevolent hypothetical concept that you are) have been tasked with choosing someone else to take his place - someone else to control the Great Spirit Robot.
You can choose any canon character from the Bionicle universe - MU or SM, alive or dead, named or unnamed, G1 or G2, so long as they appeared in the official story at some point. The only off-limit choices are Mata Nui and Teridax - anyone else at all is fair game.
My question is this:
Who is the absolute worst choice to put in control of the Great Spirit Robot?
I’ll leave the definition of “worst” up to you.
The more detailed/outside-the-box/disastrous your response, the better.
(If you’d like, you can also explore non-Bionicle characters… but please include at least one individual from the Bionicle canon in your answer, too.)
