For some reason this song reminds me of Teridax adressing the Matoran, Toa and Turaga in the Coliseum when they were celebrating their “victory”:
I just imagine Teridax singing about how he created the Rahi that made the Matoran’s lives so much more comfortable, how he crushed the Barraki, ended the Metru Nui Civil War, and got rid of the Great Spirit Mata Nui who hadn’t even cared for the inhabitants of his Universe anymore.
So the Matoran really finally should thank Teridax for all his deeds… and let themselves being ruthlessly used for Teridax’s purposes.
