Primus the Planet

It's time for the annual Christmas parody, as I prepare to take an extended break to celebrate the holidays. This year, I have a not-especially Christmasy tale set to a not-truly-Christmasy song, that nevertheless still always seems to be sung only for Christmas. Previous holiday parodies may be found here and here. Merry Christmas to all, and I'll be back after the New Year!

(to the tune of "Frosty the Snowman")

Primus the Planet
Is an old eternal soul
He's the god of light, and he's sleeping tight
So the universe stays whole

Primus the Planet
Fought with Unicron all day
Who could not be slain in the astral plane
So he tried another way

There must have been some problem
With those asteroids he found
For when he moved his spirit in
He and Unicron were bound

Oh! Primus the Planet
Caused the Transformers to be
And his children say he will find a way
To bring them to unity
