Unicron

Role in the film
Unicron is the god of all darkness and chaos in Pooh's Adventures of Transformers The Movie. This monster planet plotted to eat Cybertron and rule the galaxy in his image. Unicron used Galvatron to help bolster up his image in the Decepticon ranks. Ultimately, he was destroyed when Rodimus Prime used the matrix to blow the transfomer god into pieces. The dark god's spirit, however, survived and shall return in Winnie the Pooh and The End of the Universe as Chernabog's major partner in crime.
