In an upcoming first chapter of the Retraction series: The Merging Trio, Dr. Neo Cortex meets up with Makuta Teridax for a meeting about keeping the matoran, humans and mutants alike under Teridax's rule and preventing the new toa heroes from coming. Stick around for more of the upcoming Retraction series (which is currently in a huge re-write).

Dr. Neo Cortex goes to (sort of..) Activision.
Makuta Teridax goes to Lego.
